There’s only one problem with traveling to Thailand: deciding what to do there. And not because there is a lack of options. On the contrary, with such an abundance of options, you’ll need to make some hard choices before arriving.

Many adventure seekers are called to Thailand to explore the seas, spend days underwater, and learn about the region’s unique marine life. Whether you’re a veteran diver or just a beginner, there are as many adventures in Thailand as there are fish in the Andaman Sea. Many adventure travel programs in Thailand offer scuba lessons or certifications, but you can also opt for snorkeling or sea kayaking if diving doesn’t float your boat.

For the landlubbers, opportunities for hiking are plentiful. Explore the otherworldly stone karsts in Khao Sok National Forest while spotting gibbons, hornbills, and wild elephants. National Parks are located all over the country and guided tours are usually your best bet for wildlife viewing. To really get your adrenaline going, tie in and try your hand (and feet!) at some rock climbing. For those willing to forego a shower for a couple days, a trekking program in northern Thailand is a fantastic way to learn about local indigenous culture.
