4 days
Suitable for travelers in average physical condition who can manage short hikes, boat transfers, and basic snorkeling.
Spend four days exploring Puerto Princesa’s karst coastlines and underground river with transfers, hotel nights, island-hopping, and a city tour included. This practical package packs UNESCO-listed caves, snorkeling in Honda Bay, and local history into a compact, guided trip.
The day begins before dawn, when the city’s narrow streets are cool and the van's air-conditioning hisses against the island humidity. Passengers nod and check last-minute bags while the driver steers toward the harbor; beyond the mangroves, limestone karsts rise like folded pages of an old map. By mid-morning you're in a banca, skimming sea glass toward coral-studded islets—this is Honda Bay—and later you'll stand at the mouth of a river that eats the mountain: the Puerto Princesa Subterranean River, dark and slow, an underground world carved from limestone.

You must provide full names, ages, nationalities and arrival flight details before travel—suppliers need these for government cave permits.
Honda Bay and the Underground River sides rely on reef protection—use reef-safe sunscreen to reduce coral damage.
Rocky shorelines and slippery cave entry points make water shoes useful for traction and foot protection.
Island vendors and tipping at remote stops often require Philippine pesos—ATMs are limited on some islets.
Puerto Princesa carries WWII-era ruins and an Immaculate Conception cathedral where the first local mass was held; the Underground River has been central to conservation since its UNESCO listing.
Access to the Underground River is regulated to limit visitor numbers and protect cave formations; use reef-safe products and avoid touching corals to reduce impact.
Protects skin and fragile coral ecosystems during snorkeling and beach time.
