The sights of Koh Samui

Koh Samui is an island town separated from the mainland by a 2 hour ferry route. Its fairly underdeveloped in comparision to other towns such as Pattaya, Phuket or even Chiang Mai, though there's a significant amount of culture and geography to be explored. I recommend the following things to do/ places to visit in Koh Samui:

Place/ Activity	Picture	Description
Elephant Trekking		2000 of Thailand's 5000 elephants work in tourist outfits. One of the ways you could support their sustenance and prevent them from going extinct is by supporting eco-tourism in the country. Pick an outfit that you understand to be environment and animal friendly and join them on a trek on elephant back. If lucky you could even get the chance to be the mahout for an elephant - albeit for a short while
The Grandfather and Grandmother rocks		These strange rock formations shaped in the form of male and female genitals draw endless giggles from visiting tourists. I'm sure you can discern the grandfather from the grandmother. There's an interesting story of two lovers that drowned themselves since their families were opposed to their marriage -- and that just makes the place even funnier.
The mummified monk - Wat Kunaram		This temple contains the undercomposed remains of the ex-abbot of the shrine. Surprisingly the body shows little decomposition even 35 years after his death.
A 4x4 safari along the hilltops of Samui		I recommend Mr Ung's Magical Safari Tour which also covers the above three activities and introduces you to Samui's amazingly diverse geography.
The Golden Buddha		Koh Samui's most celebrated Buddhist monument.

Laem Sor Pagoda	Wat Silangu	Wat Samret

There are also some lesser known Wat's (temples) at Koh Samui which I recommend visiting. The photographs above are indicative of my top three.
