Ko Sichang is a bicyclist's heaven. Car and truck traffic is nearly non-existent, the air is fresh, and the views are great.

For the rider who wants to take it easy, there's plenty to see on the nearly flat roads along the populated eastern coast of the island. If you want a serious challenge, try the road across the hill from Wat Tham Yai Prik to Haad Tham Phang, or the rocky and eroded dirt roads to Samroong Leuai or the upper reaches of the quarry. Bikes are available for rent at rates of no more than B120 per day from a couple of places along the main landward road, Thanon Asdang, but if you've got a good one, bring it.
