Puerto Princesa’s claim to fame goes way beyond its swanky beach resorts and dolphin-watching cruises. The UNESCO-listed Underground River wows visitors with its low-hanging stalagmites and stalactites, and a cave that—due to its sheer size and rock formations resembling religious figures—is likened to a cathedral.

Palawan is a slice of heaven, a sliver of an island that teems with exotic wildlife, quaint fishing villages, and UNESCO World Heritage Sites. Wave hello to endangered animals at the Calauit Game Preserve and Wildlife Sanctuary or explore the Japanese shipwrecks of Coron Island, regarded as one of the best dive sites in the world. A guided boat tour of the Puerto Princesa Underground River will take your breath away.

The biggest island in the Philippines, Luzon is also one of the most diverse—it’s where mountain peaks and volcanoes meet miles of coastline, and indigenous culture melds with Spanish colonial history. You can relax at the beach in Pagudpud, hike with locals up the Batad Rice Terraces, ride in a horse-drawn carriage in Vigan, and snack on street food and dance the night away in Manila. You’ll need a few days and a bus pass, but you’ll be glad you stayed.
