Local aquanauts agree that the best scuba diving in the region is off nearby Ko Nang Yuan (just off the northwest tip of Ko Tao), which benefits from deep water just offshore and great visibility. Ko Nang Yuan consists of three small islands joined by a spectacular sandbar. Because it's famed for its wonderful snorkeling, numerous companies offer day trips here. Look into unique dive-and-stay packages at Nang Yuan Resort (www.nangyuan.com; tel. 07745-6088-93), uniquely set over the three islands, with rooms starting as low as 2,500B to plush family suites around 14,000B.
