The Land & Sea

The Land & Sea — Thailand's Natural World

Thailand occupies 513,120 square kilometres of mainland Southeast Asia — a kingdom of staggering natural diversity where misty mountain forests give way to flat rice plains, limestone karsts pierce turquoise seas, and coral reefs harbour some of the richest marine biodiversity on earth. From the summit of Doi Inthanon at 2,565 metres to the crystal depths of the Similan Islands, Thailand's landscapes form a natural theatre of extraordinary range and beauty.

This domain of the Thailand InfoBuffoon is dedicated entirely to the natural world — the geology that shaped the land, the climate that governs its rhythms, the forests and mangroves that cloak its hills and coasts, the animals that inhabit them, the national parks that protect them, and the marine environments that make Thailand one of the world's great diving and snorkelling destinations.
