- Koh Hong (near Krabi): Few can remain unmoved when they enter this seemingly unassailable limestone rock midocean. At its center is a vivid green pool completely surrounded by what seems like a limestone donut. Majestic sea eagles hover above while tropical fish flounder about in the clear waters below.
- Sea Kayaking: John Grey is a much lauded, Phuket-based eco-warrior who has long fought to protect the marine life in the Andaman Sea (especially from the tremendous pollution emitted by trash-strewing tour groups and diesel-oozing speedboats). This highly respected guide offers day or night kayak trips, promising to reveal some rarely seen ocean sights (such as phosphorescence) as well as its unforgettable wildlife.
- Khao Yai National Park (Northeast): Thailand's oldest and most visited World Heritage Site supports an abundance of wildlife, from elephants and tigers to more than 300 species of birds. Hike along nature trails or camp out and hold a vigil in high watchtowers at night, (the best time to see the nocturnal creatures in action).
- Cycle Rides: It's hard to imagine, but just a few miles from Bangkok's inner city, you'll find lush greenery that can be visited by organized bike tours. A number of websites offer cycling treks nationwide; some explore cool jungle tracks, while others visit vineyards. See www.bangkok.com/cycling-tours/index.html.
