Puerto Princesa, Palawan

Underground River

In an effort to conserve the Puerto Princesa Subterranean River, officials have set a daily limit on the number of visitors. This measure helps protect the area’s ecosystem and ensures it remains accessible for future generations. A permit is required for the Puerto Princesa Underground River Tour, and the approval process takes about three days. Travel agencies can arrange it beforehand to secure a spot on the chosen tour date.
