Chiang Dao Cave (ถ้ำเชียงดาว ''Tham Chiang Dao'), (5 km off the main highway). The best-known attraction here, offering 12 km of stalactite-laden caves, although only five of the caverns are accessible to the public. Chambers are large, but lack spectacular decorations. Bringing your own flashlight is recommended. Electricity fee is 40 baht. You can tour the lighted part of the cave alone, or hire a guide with a lantern to view the unlit caverns. It will cost you 100 baht per group (goes to the temple), plus the guide will expect the tip of about 100 baht/person.
