Sam Roi Yot National Park from Hua Hin

Thailand lucked out on the nature front – not only are there the powdery beaches washed by crystal clear waters but it's also home to lush mountainous landscapes. On this tour to Sam Roi Yot National Park, you'll discover limestone hills, vast caves and a very different side to Thailand.

Kick the day off with a boat trip over to a beach at the foot of the mountain. Then get ready to start the trek – it's thirsty work but the reward at the end is worth it. After hiking for a while, you'll reach the Phraya Nakhon Cave with its three huge chambers – light streams in through large openings in the roof. The sight is like something out of an Indiana Jones movie.

The cave is famed for the light-bathed golden pavilion commissioned by King Rama V but you'll also find interesting plant species. Your guide will point out a tree called the ‘screaming elephant' - so named for its brutal sting, which can be felt even by elephants. After strolling back down you'll enjoy lunch at the beach.
