Deep water soloing

Try your hand at free soloing over Lan Ha Bay’s emerald waters in this unique discipline of rock climbing! Enjoy a short cruise into the bay’s island labyrinth, where a small boat will transfer you to our DWS crags. Then, chalk up and get personal with the limestone. Your guide will show you developed routes and safely spot you. Climb from the boat onto the rock face, grab hold of big pockets, work up tufa systems and traverse finely featured limestone. Push your limits to climb higher before jumping from the cliff into the water. It’s a thrilling, adrenaline-pumping experience! 

Refuel with a Vietnamese lunch cooked fresh by our crew on our traditional junk boat. Relax on the top deck while we cruise to a new location for the afternoon, then hit the crags again for some harder climbing before heading home while the sun sets. 

Typical route grades range from F5b to 7c/ YDS 5.8 to 5.12c. Since our DWS crags are undercut by natural erosion, route difficulty depends partially on tides. A boulder start is required to begin climbing during low tides.

*All deep water solo routes have been developed by experienced rock climbers in areas safe for climbing. Asia Outdoors is the only tour operator in Cat Ba licensed to deep water solo.

No. Most basket boat drivers do not understand  practices required to safely deep water solo. Additionally, they do not know which walls have water deep enough (and clear of hazards) for a safe landing, and do not know when tides are right. Because Lan Ha Bay is part of Cat Ba National Park, licenses are required to deep water solo. Asia Outdoors is the ONLY company licensed to run DWS trips in the region. Hiring an independent basket boat to take you deeping is both dangerous and illegal!
