Adventure takes many forms : a new relationship or job, sushi for the first time, or even a walk through an L. A. slum at 2 am on a Saturday night – all qualify.  Webster’s dictionary defines adventure as “an exciting or remarkable experience. ” It’s when we break out of our daily routine and dare to take on a new challenge, boldly going into territory that is unfamiliar to us.  But most people, when they think of adventure, think of travel. And though pretty much the whole world has been explored before by other people (with Marco Polo setting the benchmark several hundred years ago), what matters is that it is your discovery. Adventure travel is a highly personal thing and what it teaches you about the vast world that surrounds you and its relationship to you is what makes it both worthwhile and essential. This is probably why adventure travel keeps growing in popularity. In a world gone wrong, cluttered with technology, self-interested politicians, bureaucracy, greed and numerous other complications, it is crucial to get back to the basics of life and to set personal challenges that bring out the noble savage in us. So remove yourself to another place, with strange people and customs, follow your nose, trust your instincts, and find a part of yourself you’d almost forgotten. Thailand is an ideal location to live out these dreams – or alternate realities. With more than 25,000 square kilometers of national park land, islands, mountains, and a welcoming people, new and enlivening experiences are waiting for you to live them out. Though there are endless adventures available here, two of the more popular possibilities involve going as high and as low as you can. Scuba Diving : The Amphibian WithinThere’s no getting around it. It’s programmed into our DNA that we are creatures of the sea, with a deep-seated desire to return to it. Meander aimlessly on thoughtful walk some lazy Sunday and your feet, of their own accord, will inevitably take you to the water – a lake, a pond, an ocean or a very large puddle – whatever is closest. We look out and yearn to return to our roots. Thanks to Jacques Cousteau, it is now possible, for a short time anyway, to return to the sea completely – for as long as the air in the tank lasts. Thailand, with its countless beaches, coral reefs and modern dive schools is a popular spot to learn to scuba dive. Thousands of proud new divers earn their PADI international dive certificates every year. It can be a bit scary at first – our instincts also tell us that we can’t breathe under water – but once you master the basic technicalities, there’s no experience like it. You have freedoms undreamed of by land dwellers. You are weightless, and can go left, right, forward backwards, up and down – and you are surrounded by colourful fish and plants. It’s another world down there. But like anything worthwhile, it does take a bit of work and discipline to make your first dive. Over the course of a week or so, you take a step by step open water course to ensure maximum safety. You’ll start out in a classroom, studying buoyancy and pressure – you even have homework and exams to do (What? Homework at the beach?!!) This is combined with practice, starting in shallow water, learning to use the equipment getting comfortable with the idea – and soon you’re heading off to the open water by boat, working your way up to dives as deep as 18 meters. In less than a week, you are granted your certificate and can dive anywhere in the world unaccompanied – the beginning of a beautiful new friendship with the other two-thirds of the planet.  Where to Go UnderWith more than 3,000 km of coastline and countless islands, Thailand has enough dive sites to keep any enthusiast busy for a lifetime. Most divers head out from island and mainland areas on day trips, but it is also possible to explore more remote and less inhabited areas on liveaboard boats, heading out for several days at a time. All of the places listed have several certified dive schools. On the Gulf of Thailand side, or east coast of Thailand’s southern peninsula, the main diving area is in and around the Samui Archipelago, which includes the main islands of Koh Pa Ngan, the well-touristed Koh Samui, and Koh Tao, which is the country’s most popular diving island, featuring several coral reefs a short boat ride away. On the Andaman Sea side, or west coast, are the islands of Phuket (the most popular holiday island in the country), Koh Phi Phi, the Krabi mainland, and the up-and-coming Koh Lanta. Central Thailand’s south coast also has a few spots. Some divers base themselves in the wild nightlife town of Pattaya, but it’s a bit of a boat ride to the best dive sites. Heading east, almost to the Cambodian border is the Koh Chang National Marine Park, a group of more than 40 protected islands, surrounded by coral reefs. Trekking : Because it’s there. Thailand’s north is a gorgeous place where lushly vegetated mountains rise majestically from the earth – the tropical tail end of the Himalayan chain. For some mysterious reason mountains were made to be climbed. There seems to be an innate desire to struggle to peaks and look down on creation as if we were God almighty. When you are at a great height, taking in vast areas of creation in a single glance, the world, for a fleeting moment, belongs to you alone. In Thailand’s north, you can do just that, with the added bonus that along the way, you can rest overnight with Thailand’s hilltribe people. There are several different hilltribes, including the Akha, Meo, Lisu and Lahu – all with their own unique traditional lifestyle. These people migrated from Southern China into what until relatively recently was uninhabited territory less than two centuries ago, and set up shop as subsistence farmers. Treks can run from two days to a week or more, as you hike through the jungle pathways on foot, by elephant (a daunting prospect at first), and by bamboo river raft, breathing fresh air, watching abundant wildlife and tiring your limbs, until you come upon the welcoming hilltribe village that you will call home for the night. An evening with a Thai hilltribe is an unforgettable experience. After your hike, the food tastes fantastic, and along with the villagers you settle sit around the fire, singing songs and watching traditional dances – be prepared to do a number or two yourself from your home country. After a few hours with these charming people, you may find yourself tempted to give up your career in accountancy, or whatever it is you do back home, shed yourself of all your possessions and live the simple life of honest hard work and a bowl of rice at the end of the day. Tempted, yes, but after a little reflection on the labours you have to put in for that rice bowl, you’ll probably opt to take home a few of the colourful handicrafts, and treasure your memories from the land of comfort from whence you came. Really, it’s better this way. Trekking : Where to StartChiang Mai, in Thailand’s mountainous north was the original home of hilltribe trekking, but in recent years a few other places have gotten into the act. Chiang Mai itself is a relaxed city of about one million people, and the springboard to some great trekking locations, including Doi Inthanon National Park, which is the host to Thailand’s tallest peak at 2700 meters. The second city of trekking is the more somnambulant Chiang Rai, a bit further north. Both cities have very good airports and regular flights from Bangkok and elsewhere. One young upstart in Thailand’s trekking world is Nan, northeast of Chiang Mai, and the coldest spot in Thailand (which is nonetheless pretty darn warm if it snows in your hometown). New luxury hotels have been popping up here recently, yet many of the hilltribes in this area are new to visitors – so it’s possible to enjoy the best of both worlds. Also becoming popular is the charming little town of Pai, which has developed into a Bohemian arts center for disillusioned hippie folk from both Thailand and abroad. The town is in the valley, surrounded by evergreen and rugged mountains with several trekking trails and hidden waterfalls. Thailand has beautiful place very much if you come to tour in thailand , assure that ,you do will not be defeated certainly.
