Philippines

The crystalline waters of Bacuit Bay are a fantasy-scape of jagged limestone islands, mesmerising from any vantage point, whether under the water, in the air or lying on a beach. Easily the rival of southern Thailand or Halong Bay in Vietnam, the islands hide so many white-sand beaches, lagoons and coves, not to mention hundreds of species of fish and coral, that you’ll be overwhelmed.

The tiny island of Pamilacan, adrift in the Bohol Sea about 23km east of Balicasag, is cetacean central, its rich waters supporting marine megafauna including whales and dolphins, manta rays and sharks. Islanders have always lived off the sea, hunting whales until the ban in 1992, then targeting sharks and rays. In 1993 Sulliman University recorded 30 whale sharks landing in Pamilacan in just 44 days. If you visited the island in the mid-1990s, lanes would be full of shark and manta meat drying in the sun. Finally, in 1998, whale shark and manta hunting were officially banned.

For most Filipinos, Siquijor is a mysterious other-world of witchcraft and the unknown. True, this tiny island province is famous for its mountain-dwelling mangkukulam (healers) who brew traditional ointments for modern ailments. But these days Siquijor's most popular healing practice involves a cocktail and a deck chair at any number of its laid-back and wonderfully affordable beach resorts. Attractions include great diving, waterfalls, caves and forest walks in the hilly interior. Just about everywhere on Siquijor is great for snorkelling – find the nearest beach and dive in. Like many beaches in the Visayas, swimming is only possible during high tide, and wearing thongs (flip-flops) is recommended as protection against sea urchins.

Home to dazzling white-sand beaches and astonishing coral walls, the world's smallest mammal and its biggest fish, eastern Visayas are the aqua heart of an island nation. This region's natural appeal is utterly compelling – the Chocolate Hills of Bohol and shimmering millions of sardines of Moalboal, waves and caves of Samar and waterfalls and rice terraces of Biliran.

This was Typhoon Yolanda's “ground zero”. Tacloban took a direct hit on 8 November 2013, when the mother-of-all tropical storms destroyed the city. Yet as you walk through Tacloban's streets today, it's impossible to imagine the apocalyptic scenes on that fateful morning. The center has been fixed up, hotels have been repaired and there's even a degree of cafe culture evident. Tacloban's bars are again filled with local drinkers instead of relief workers. Yes, the city has resumed its role as the commercial heart of both Leyte and Samar.

Bisected by a virtually impassable mountain range – aptly named the High Rolling Mountains – rugged Mindoro is part tropical paradise, part remote getaway. Forming a dramatic backdrop almost everywhere, the mountains separate the island’s two provinces: rough and rugged Mindoro Occidental to the west, and more prosperous Mindoro Oriental to the east.

Manila has outstanding sightseeing it's true, but visitors who put in the effort will discover its creative soul – from edgy galleries to a lively indie music scene. Combine this with a penchant for speakeasy bars, artisan markets and single-origin coffees, and it's clear to see that Manila is not only one of Asia's most underrated cities, but one of its coolest.

Those looking for the perfect beach destination will love Bantayan Island. Its blinding white-sand beaches are some of Cebu's very best and the island's mellow, easygoing vibe is highly seductive. With little traffic, it's a wonderful place to explore by scooter – circumnavigating the coastline makes a fine day out. Offshore there's a blissful tropical islet, deservedly popular as a day-trip destination. However, Bantayan does not have any rewarding dive sites and the snorkelling is pretty limited too.

This group of islands in the far north of Palawan, also known simply as the Calamianes, is a bona fide adventurer's paradise, with wreck diving, kayaking, island-hopping and motorbiking leading the way. It's a bountiful region filled with white-sand beaches, coral reefs, dense rainforests, mangrove swamps and the crystal-clear lakes of Coron Island.

For students and historians of the Pacific and WWII, the word 'Leyte' conjures up images of bloody naval battles and the site of MacArthur's famous return. For Filipinos it's equally associated with the rags-to-riches rise of Imelda Marcos and the nostalgic, romanticised portrait she painted of her birthplace after she made good in the capital. For travellers, Southern Leyte, wrapped around the deep-water Sogod Bay, is one of the Philippines' many diving hotspots. The Cebuano-speaking Leyteños live in the south, and their Waray-speaking neighbours live in the cattle-ranching country of northern Leyte.
