Canoeing and kayaking are two sports under the umbrella term of paddling. Not for the faint of heart, these beloved water sports are as invigorating and as challenging as you make them. Some of the world's most beautiful scenery can be viewed the bow of a boat, be it floating down a river or on the open sea.  But don't limit your watery adventures to the conventional cruise ship.  Canoeing and kayaking allow you to immerse yourself in your surroundings more than you can from an observation deck, and they provide many people with a great sense of gratification.  If you are looking to explore the outdoors--a tranquil meander down a river, a thrilling race through rapids, or somewhere in between, then your best bet is to gear up for a canoeing or kayaking trip.  Domestic and abroad, there are many destinations that are bound to take your breath away.  Here are some of the world's best places to paddle, regardless of whether you are a novice or an expert. 

Zambezi River, Southern Africa

If you are looking for a canoe expedition that doubles as that African safari you've always been meaning to do, then the Zambezi River in Southern Africa is the destination for you.  While we do not recommend you do it alone--for hippos are not as friendly as they appear--there are many options for guided trips along both the Upper and Lower Zambezi.  The Upper Zambezi provides the adventurous with the opportunity to try their hand at mild rapids, and offers the occasional glimpse at the white rhino, an endangered species.  The Lower Zambezi Valley is home to Mana Pools National Park, one of the best places in Africa for viewing game such as elephants and black rhinos.  If you are up for a challenge, why not do both sections?

Dordogne River, France

For those who are looking for history, scenery, and relaxation, look no further than the Dordogne River in France.  Flowing through the southwestern region of the country, this river is wide and slow moving, making it the perfect way to enjoy the countryside and save the adrenaline for another day.  There are several affordable places to rent canoes and kayaks close to the river, as well as many campsites along the shore.  Your float down the majestic river will take you past medieval castles and Gallo Roman ruins, straight through the heart of the countryside.  Don't expect to have the river to yourself, as this is a popular tourist attraction.  For more privacy, consider taking a trip in the spring or the autumn.  Chances are that the weather will still be beautiful.

Coastal Thailand

A great way to experience Thailand is from the water.  Float around Phang Nga Bay exploring the "hongs", or limestone caves, from the comfort of a kayak or a sea canoe.  The hongs are a system of collapsed caves that have become home to a diverse array of wildlife including monkeys and birds.  Phang Nga Bay is a popular tourist destination, and kayaking tours are among the most popular activities in the region.  To avoid the crowds, you may want to consider going to Ang Thong National Marine Park, an archipelago of over 40 islands around which you can paddle, fish, and snorkel to your heart's content.  The kayak is the perfect vehicle for delving into the heart of the reserve.  

Broken Group Islands, Vancouver, British Columbia

If a tropical trip does not tickle your fancy, perhaps the Broken Group Islands of Vancouver, British Columbia will.  Not only are these islets and coves ideal for spotting the best of North American wildlife--think bald eagles, grizzly bears, and orca whales-- they are also remarkably peaceful and undeveloped.  Camp along the sandy shorelines, explore caves, and put your mind at ease.  The islands are favorable for canoeing and kayaking because they are largely protected from the elements of the open ocean.  Many choose to explore the islands with a guide, but it is also navigable alone.  Expect to share the experience with a few scuba divers, some sailboats, and a handful of sea otters and porpoises. 

Ha'apai Islands, Tonga

If you truly want to leave the world behind, then head to the South Pacific.  You will find that sea kayaking around the Ha'apai Islands of Tonga will be the perfect getaway.  Referred to as the "sea kayaker's dream," these islands are truly off the beaten path.  Explore the coral reefs and secluded beaches while paddling through schools of colorful fish.  If your timing is right, you may even cross paths with a humpback whale, which migrate here annually for mating and calving season.  You will probably meet some Ha'apai islanders, who are known as the friendliest people in all of Tonga.  Float past towering volcanoes and through secret lagoons to capture the island vibe.

A place is hard to define. Places change. People change.  And in many "must-see" locations, they inevitably become entrenched on the tourist trail, losing the charm which put it there in the first place. But the Himalayas is one for the books.

This is happening - right this very instant - on the Annapurna Circuit.

If you haven't hiked this incredible 17 day trekking route through Nepal's Himalayas, don not delay. What once was an awe-inspiring walk through isolated villages is increasingly becoming a magnet for anti-hikers; jeeps roar up the western slope, carrying tourists too lazy to put one foot in front of another. As you can imagine, these slopes become congested in the afternoon, as Jeeps kick up dirt and gravel on hikers.

But fear not... for now.

The eastern side remains relatively unscathed from the tourist boom. The paths remain open to hikers, the people as charming as ever, and not a Jeep in sight.  The same goes for higher elevations  on the western side; for now, Jeeps only run up to Jomsom, which gives hikers three full days of (almost) traffic-free trekking.

Hiking the Annapurna Circuit- What to See, What to Skip

The Annapurna Circuit is connected by two river valleys: the eastern Marsyangdi, then down the Kali Gandaki in the western slope. A recently completed road allows jeeps and tour buses to drive up the Marsyangdi to the base of the pass.

Most trekkers prefer riding in jeeps than walking behind them, which as a results cuts the trekking time from 17 days down to 11. And with a road planned to run up the eastern slope, what was once the world's greatest trek will become a short, four-day hike.

It hurts to say this, but: trekkers may be better off with Jeeps.

My wife and I completed the 17 day trek, and (no pun intended) the trip goes significantly downhill from Jomsom. While mountain vistas remain spectacular, the constant back-and-forth of jeeps and tour buses feel more like walking a busy rural road than trekking. Which, of course, is why most people flock here.

Therefore, my suggestion is as follows: start in Khudi, and begin your hike counter-clockwise. Stop in Manang for a mandatory acclimisation day, then go over the Thorong La Pass, and down into Jomsom. From there, hop on a jeep and head either to Tatopani (where you begin the hike up to Poon Hill) or to the end of trail, where buses regularly leave for Kathmandu and Pokhara.

Sunrise views from Poon Hill are renowned for their beauty; however, its easy access make for a crowded visit. And if you've hiked for two weeks already, you can't help but wonder what all the fuss is about.

Tourism Dollars vs. Local Interest- Compatible?

I've heard older travelers lament the loss of idyllic destinations (Thailand, Bahamas, Goa, etc.) and perhaps I've even seen places change over time as word spread. But never - in all my travels - have I seen a location in such transition. You can almost see "progress" increase day by day.

Of course, this is only one viewpoint. How do local residents feel about such aggressive growth?

The answers I heard appeared directly related to financial interests. Obviously, hotel operators, tour guides, and porters are thrilled with increased exposure and business.

Well, actually... they aren't.

In fact, tour operators are against it, because they know the road will kill their business (or at least reduce the need for guides).

But what about locals with no vested interest? What do they think?

The truth is, nearly everyone - besides tour operators - are excited about the road. It opens up their world, even if it does close the book on a world-class trekking experience.

As an ardent traveler, I understand locals should have the first and last word about their infrastructure.  And it most cases, it's the right thing to do...

...but in cases where beautiful, cultural places are picked clean by the tourist trail, is it really the right answer?

Travelers, take heed: the Annapurna Circuit remains one of the best treks in the world. But for how long?

While not for the faint of heart, whitewater rafting is a great activity for those who are adventurous enough to give it a try. Whether you're a first-timer or a seasoned pro, it's hard to beat the thrill of cruising down a winding river, water splashing all around you anxiously anticipating the next set of rapids.  However, with so many rivers to choose from, it can often be a tough decision where to unleash your wild side. Are you a beginner looking for Class I and Class II rapids or are you a whitewater expert who is looking for their next big challenge?

From Pennsylvania and Oregon in the U.S. and Chile and Ecuador in South America, there are opportunities for whitewater rafting all over the world and if you know what you're looking for, the sky's the limit. Do you want a guided tour or do you and a group of experienced friends want to brave the waters yourself?  Here we look at some of the best whitewater rafting in the world- for beginners and experienced rafters alike.

Alsek and Tatshenshini Rivers, Alaska/Canada

Glaciers and icebergs are among the main attractions on these two rivers flowing through a breathtaking wilderness of mountains and tundra on the borders of Alaska and Canada. A trip through the upper Alsek is an incredible journey through one of the largest protected parks in the world. Beginning in Kluane National Park in Canada's Yukon, catch sight of spawning salmon or a grizzly bear as you wind through the Tatshenshini-Alsek Wilderness Provincial Park in British Columbia and ends in Alaska's renowned Glacier Bay National Park. A perfect excursion for the photography lover, wildlife is abundant with wolves, moose, deer and occasionally a wolverine. Float through the largest non-polar ice cap in the world through a spectacular 30+ miles of the lower Alsek River to Dry Bay with opportunities for a glacier walk along the banks. There are numerous tour companies that take trips along the Alsek and Tatshenshini, so you're sure to be able to find the perfect pace and level for you.

Middle Fork, Salmon River, Idaho

As one of the world's most popular whitewater rivers, the Middle Fork Salmon River has something for everyone. There are rapids up to Class IV and glorious alpine and forest scenery that flows through America's largest road-less wilderness area outside Alaska. Wildlife is abundant and can include the occasional mother bear and her cub swimming or the ever-popular moose and deer sighting. Middle Fork flows through the Frank Church River of No Return Wilderness, the largest forest in the lower 48 states and is the historical origin of white water rafting trips. Boasting 100 frequent rapids for over 100 miles, hot springs and reserved forest campsites, a trip down the Middle Fork Salmon typically starts at Boundary Creek boat launch, just below Dagger Falls. The first 22 miles to Pistol Creek Rapid are very fast as the rapids follow one another in quick succession. The alpine section offers class IV rapids that are continuous through Velvet Falls and Pistol. Velvet Falls, 5.5 miles from the put-in, is a short, steep drop into a river-wide reversal. The difficulty of the rapids may not be for beginners, but veteran rafters love the challenge and adrenaline-inducing speeds that the river has to offer.

Rio Upano, Ecuador

The Rio Upano or "River of the Sacred Waterfalls" offers a true sensory experience with nature, as rainforests engulf you with Toucans and iridescent butterflies. Starting in the remote town of Macas on the far western fringes of the Amazon Basin, you can embark on a journey where the pace varies from gentle rapids to tumultuous rides through narrow canyons. The Rio Upano treats you to Class II-IV whitewater rapids, mammoth waterfalls and glimpses of native Ecuadorian tribes. The highlight of the trip is the Namangosa Gorge, with Class IV rapids and a number of waterfalls plunging down the gorge's sides. This is a great river for beginners and experts alike, as it has challenging but manageable whitewater, in addition to good hiking trails and beautiful riverside camps when you want to take a break and enjoy the surroundings. Add in the area's amazing cultural history and contact with the Shuar Indians along the rivers banks and you've got a rafting adventure that's physically challenging and mentally and spiritually invigorating.

North Johnstone River, Australia

The North Johnstone is a steep, natural flow river that carves its way through a spectacular volcanic gorge. This stunning river in the tropical far north of Queensland offers Class IV and V whitewater rapids amidst the volcanic gorges and the ancient rain forests of Palmerston National Park. At night, rafters can view luminous fungi glowing on the rocks and fireflies dancing through the forest canopy. Best of all, you don't have to worry about what time of year to visit because the park and rapids are always in pristine condition. There is a limited frequency of departures, restricted group sizes and stringent National Park permits that ensure that the North Johnstone River and surrounding ancient rainforests are preserved, enabling rafters a rare glimpse of a very precious and untouched part of North Queensland's World Heritage Rainforests. Whether you're looking to challenge yourself with Class V rapids or simply want to float along and enjoy the breathtaking scenery, the North Johnstone River is one not to be missed for rafting enthusiasts.

Zambezi River, Zimbabwe/Zambia

Commercial rafting first began on the Zambezi River in 1981 and since then has grown in popularity to the point where a rafting trip on the Zambezi is now a regular feature in most tourists' itineraries. More than 50,000 people a year enjoy whitewater rafting on the river claimed as the best rafting trip in the world. Classified as a high volume, pool-drop river, there is little exposed rock either in the rapids or in the pools below, making it extremely challenging. The distance between rapids varies from 328 feet to 1.2 miles and the Batoka Gorge, where the Zambezi churns its way over 23 rapids, is approximately 400 feet deep at the put-in point and 750 feet at the take out point. The British Canoe Union has classified the river Grade 5, which means "extremely difficult, and has long and violent rapids, steep gradients, big drops and pressure areas." In fact, nearly half of the rapids you'll come across are Class V, which is the toughest you are allowed to raft. Due to the steepness of the gorge, wildlife is not abundant, but adventurous rafters should have enough adrenaline to make up for the lack of nature.

While competitive and serious runners compete in large scale regional marathons, those looking to partake in running for sport, fitness or fun may enjoy one of the many smaller 5 K races around the nation. Running has become quite trendy as a hobby, evolving into it's own subculture and with the increased interest from young urbanites,  more and more quirky 5 K races and 10 K runs have popped up for a variety of charities, causes or just for kicks. Take a look at some of these weird races, don your best running shoes and wackiest costume and get your kicks at these 5 Ks- the best races in America. 

 Muddy Buddy

Traverse a 6-7 mile off-road course neck deep in mud, while competing in five obstacles in teams of two at Columbia's Muddy Buddy. With one person running and one on the bike, after the first obstacle, the rider will drop the bike, complete the challenge, and begin running. The runner will arrive, complete the obstacle also and switch to the bike. Teams will continue leapfrogging each other through the entire course. Locations and dates vary across the country so if you're in the mood to get physical- roll your pants up and get ready to get dirty. The mud pit at the end is the celebratory prize for crossing the finish line. 

Bay to Breakers

Touted as America's biggest streaking event, this San Francisco fun run dares you to bare it all to promote the acceptance of the public nude figure. Held every year in May, "the running group with a wardrobe malfunction"completes 7 1/2 miles for pride, a celebration of organized chaos and gives everyone a chance to cross freewheeling off their bucket list. Initially called the Cross City Race, the original 147 runners in 1912 subsequently reached an estimated 110,000 participants in 1986.  In 2010, an estimated 60,000 people participated with a reported 33,000 registrants. The event comes highly recommended because everybody should run through the streets [naked] at least once in their life.

Men's Health Urbanathalon

A full-fledged downtown obstacle course taking place in the fall, racers compete in waves based on their qualifying times in separate male and female heats. Enter as an individual to run all 9 miles by yourself or compete on a three person relay team for group bonding fun. A combined 40,000 runners between the three host cities, Chicago, New York and San Francisco come out to participate in the Road Rules style physical challenges. Are you up to the challenge of running through tires, swinging the monkey bars and other tests of brute strength? 

Keep Austin Weird Fest and 5 K
