Phong Nha-Ke Bang / Dark Cave

Dark Cave & Chay River Adventure

An activity park on the Chay River: zip-line about 400 m across the river to the mouth of the Dark Cave, explore it by headlamp and wallow in a natural mineral mud pool deep inside, then kayak, swim and try the water slide and obstacle bridge. Cheaper packages skip the cave. Bring swimwear, a towel and a change of clothes; waterproof phone pouches are sold on site.
