Arriving at Koh Samui Airport, meet your English-speaking guide for your private transfer to your hotel. The remainder of the day is at your leisure for relaxation or exploring.

Today enjoy a shared tour as you'll spend a day in the remarkable Angthong National Marine Park. Between the limestone cliffs, the stunningly beautiful landscape, and the diverse marine wildlife, Angthong National Park is the very picture of paradise with 42 islands spread across the azure Gulf of Thailand. The protected marine reserve is filled with lush forests, gigantic limestone formations, hidden lagoons (one of which inspired the novel "The Beach" by Alex Garland) and uninhabited beaches. You'll have a few options including snorkeling, trekking for incredible views of the seascape, or just relaxing on white sand beaches.

Today is a free day at leisure to relax and explore on your own, or take an optional tour.

The Private Koh Samui Island Tour will cover a visit to the Buddhist site Wat Phra Yai. This 40 foot tall golden sitting Buddha statue is so imposing, it can actually be seen from a plane. Ladd Koh Lookout; Postcard-like beautiful panorama of the turquoise sea and Chaweng's 4 mile long white sandy beach. At the Wat Kunaram, you'll see the biggest monument in Thailand. Standing at 16 meters high, it celebrates the life of a legendary warrior called Guan Yu. You'll also witness the mummified body of the hallowed Buddhist monk Loung Por Daeng, posing in meditation since his death two decades ago.

Afterwards take a refreshing stop at the majestic Na Muang Waterfall, one of the must-see sights in Koh Samui.

After breakfast, meet your guide in the hotel lobby for your private transfer to the airport for your return home, or onward to your next Avanti Destination!
