If you have never visited Cambodia before and are limited on time, the highlights not to miss are the ancient, UNESCO World Heritage-listed temples of Angkor, including Angkor Wat, and the Mekong riverside capital of Phnom Penh, once regarded as the Venice of old French Indochina.

The Mekong Explorer is a sample bike, boat and kayak adventure following the mighty Mekong River from southern Laos into northern Cambodia, including the ancient World heritage site of Wat Phu, the 4,000 Islands, where the Mekong is at it widest, and the Ramsar flooded forests in Cambodia's Stoeung Treng (Stung Treng) Province.

The mountainous provinces of the Cordillera, Northern Philippines, are perfect for trekking. This is the territory of former headhunting tribes who were also the master hydro engineers who constructed the world's first and most impressive rice terraces over 2000 years ago - considered by some to be the eighth Wonder of the World.

The Philippines is an overlooked treasure of Southeast Asia, but that's due to its remoteness, not for lack of natural gems that range from coral-fringed islands, palm lined white-sand beaches to hot springs and majestic volcanoes.
