"I climbed and did my first caving and ascender use (Jumar) with Chiang Mai Rock Climbing Adventures (CMRCA). The experience was stunning and memorable. We waded through above-knee water while moving from one room to another in the cave. Crystalline deposits, spiders, worms, crickets, and bats enhanced the visit." - Dr. Alan Morris, Vertical Caving

Rock climb in Northern Thailand’s scenic beauty, unwind in hot springs, visit holy caves, enjoy local cuisine and spend unforgettable times with us.

As we trek through the jungles of Northern Thailand or climb the vertical at Crazy Horse we remain constantly aware of our impact on the natural settings around us. Here at CMRCA we are not only outdoor adventurers, but environmental enthusiasts that support sustainable tourism, development and protection of natural habitats.
We were excited to learn about the work of the Wildlife 1 Foundation. The organization is based in Thailand, but is working to protect ecosystems and endangered species throughout South East Asia. Read more about their work.
