Cool off and enjoy nature at the Mooc Spring Eco Trail (Suối Nước Moọc), a beautiful recreational area where an underground river emerges into a stunning turquoise spring. Walk along bamboo bridges and pathways through the forest, crossing the crystal-clear stream.

Activities include swimming in the cool, refreshing waters, kayaking, relaxing in waterside huts, or trying the suspension bridge rope swing or 'polar plunge'. The Mooc Spring offers a fun and scenic way to enjoy the natural beauty of the Phong Nha-Ke Bang region.
