Located just off Boho Island (the Philippines' largest), Planglao is home to pristine beaches and luxurious hotels. The island's Alona and Dumaluan beaches in particular serve up the white sands and turquoise waters that have become a trademark of the Visayas region.

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.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship. On shore, the lush jungle shelters stone temples and mischievous monkeys. The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

Thailand’s largest island is an international magnet for beach lovers and serious divers, who enthusiastically submerge themselves in the Andaman Sea. Blue lagoons and salmon sunsets make for a dream-like atmosphere, and indeed, a vacation here can feel a bit surreal. Watersports are the most popular activities, though once you’ve had enough sun there’s still plenty to explore at the island’s aquariums, gardens, and Buddhist temples.
