Koh Tao Climbing Guidebook
Your best resource for rock climbing Koh Tao
Koh Tao is a granite heaven located in the middle of the beautifully clear tropical seas of Thailand’s Gulf. The island itself is made of volcanic rock, with large boulders dotting the landscape and shaping its topography and coastline.
The climbing options on Koh Tao are extensive. From mountain top complexes of walls and routes with amazing panoramic views, to seaside cliffs with erosion patterns etched into the rocks where you can climb and watch fish swim amongst the corals below. You’ll also find lowland boulder fields amongst coconut plantations and huge isolated rocks deep in the jungle, just waiting to be climbed.
Goodtime Adventures has been developing rock climbing on Koh Tao since 2007 and has led the way in top rope, sport leading, and traditional climbing routes. Prior to the birth of Goodtime Adventures, only some boulder areas had been mapped by James March (Zen Gecko), who was the first to see Koh Tao for its amazing climbing potential. Since then, we have put in over 70 routes in 3 main areas – along with some new and exciting bouldering areas.
We offer two guidebooks for information on the best climbs on Koh Tao. First is a free guide co-created by our team and James, and the only one with information on bouldering in the area. The other book has the most up-to-date information, with over 180 routes across our small tropical island from the climbing guidebook company Rakkup.
