Khao Khanab Nam are two striking limestone mountains that stand as iconic landmarks of Krabi, Thailand, flanking the Krabi River. Visitors can explore caves within the mountains, featuring impressive stalactites and stalagmites, and learn about local legends associated with the area. Accessibility can be limited due to the boat access required to reach the mountains. Solo travelers can easily join boat tours, while guided tours offer more in-depth information about the caves and the surrounding ecosystem. The best time to visit is during the dry season (November to April) for calmer waters and clearer skies. A boat trip to Khao Khanab Nam typically costs a few hundred Thai Baht per person, and a visit usually lasts around 2-3 hours. Keep in mind that the caves may involve some walking and climbing, so comfortable shoes are recommended.
