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.

Why settle for a beachfront hotel when you can stay right over the ocean in a cottage on stilts? And why settle for any old dive site when you can snorkel in an orchid-walled lagoon? El Nido is known as the Philippines' last frontier, and if you're looking for magnificent beaches in an unspoiled setting, it's a perfect place for you to vacation.

Tagaytay secures its place on most Philippines itineraries with its location above Taal Volcano's active crater. Views of the crater lake and a refreshingly cool climate make the town an enticing destination—not to mention the famously unfinished People's Park in the Sky.

White-sand beaches set the scene for a romantic tete à tete in Jimbaran, a quaint fishing village in Bali, Indonesia. Luxury hotels mingle with simple seafood shacks on the waterfront. Feed your paramour succulent chunks of freshly-prepared fish, then amble along the beach under the Indonesian moonlight before retiring to your five-star accommodations for the night... and the next morning.
