Boat tours around Koh Samui, Koh Samui
Concierge.com's insider take:
Private Thai-style boats known as longtails are an ideal way to explore Koh Samui and its surrounding islands. The Five Islands Experience (Five Islands Beach, Taling Ngam; 66-77-415-359; www.thefiveislands.com) leaves from Five Islands Restaurant on Taling Ngam beach, taking in Koh Samui's soaring limestone pinnacles and rare bird-nest harvesting spots. The nests are sold for use in the Chinese delicacy bird's nest soup. You'll stop for snorkeling before returning to Taling Ngam for fresh seafood with coconut and lemongrass.
