Dragon Crest Mountain (Khao Ngon Nak) offers a challenging yet rewarding hike near Ao Nang, Krabi, known for its breathtaking panoramic views of the Andaman Sea and limestone karsts. The trail is well-marked, making solo visits feasible for experienced hikers, though guided tours can provide convenient transport and insights; expect a 5-8 hour round trip depending on fitness. While generally free to enter, transportation to the trailhead will be the main cost. The best time to visit is during the dry season (November to April), as the trail can become very slippery and dangerous during the monsoon season (May to October), when it may even be temporarily closed. Essential tips include bringing plenty of water, sturdy hiking shoes, sunscreen, insect repellent, and starting early to avoid the midday heat and crowds at the summit's famous 'hanging rock' viewpoint.
