Sabang 3-in-1 Adventure: Underground River, Zipline & Mangrove Tour from Puerto Princesa
Select participants and date
You push off from a crowded jetty and the water takes you past wooden banca bows and fishermen mending nets. The town of Sabang slides astern, a fringe of palms and low concrete houses, while the limestone ridges of the Puerto Princesa Subterranean River National Park rise like folded sheets of stone ahead. In a single day you move from sea-spray to cave hush to high, wind-thinned air: a zipline 800 meters long, a guided boat through a cathedral of stalactites, and a slow, close-in tour through a living mangrove forest.

Check medical restrictions
The zipline and cave ride are not recommended for pregnant travelers or those with back or serious heart conditions.
Carry small change
Vendors at Sabang and guide tips are often cash-only; bring Philippine pesos in small bills.
