Casual wear is acceptable in most places, but modest clothing is encouraged, especially when visiting rural communities or churches. For island hopping or beach trips, bring swimwear and a cover-up.
Subterranean River
As a measure for environmental conservation, authorities control how many tourists can visit Puerto Princesa Underground River each day. This helps protect the wildlife and keeps this national park beautiful for future generations. Anyone wanting to take the Puerto Princesa Subterranean River Tour must get a permit, which takes about three (3) days to process and may lake longer during peak season. Advance booking through a local travel agency may help secure a slot.
