Butterfly Valley (Lien Minh)




The best crag of Cat Ba Island.


Routes listed L to R.

Access issues

Visit Langur's Adventures in Cat Ba Town for an access pass. It's free and ensures a good relationship with the land owners. The valley floods in the rainy season so some of the climbs are inaccessible, an alternate walk in around the upper mantle is available.


The crag is located 10 km from Cat Ba Town, ask at Langur's Adventures for a detailed approach description.

Where to stay

At the basic camp called "The Hive" under the crag or in Cat Ba Town.

UPDATE 16.0.2019: Around 12 months ago this tree was struck by lightning, we have had to remove it, therefore changing the climb dramatically. now renamed Reggae Rocks at 5c Consider back-cleaning the first few bolts to avoid rope drag. A really fun climb up nice holds and tree roots! Can be extended another 6m and 3 bolts to a higher anchor.

FA: Erik Ferjentsik, 2007

Consider stick-clipping the first bolt. Following the bolt line is the direct route, though many take an alternate start a bit to the left and closer to You Enjoy Myself. Stay on the arete and avoid coming out right onto the face for the true line!

FA: Erik Ferjentsik, 2007

Traverse the face on pockets to a slopey ledge. The direct line goes straight up the roof, though some feel this is contrived and opt to traverse left up the ledge and direct to the anchors.

Small holds requiring enduring power.

FA: Steve Bradshaw, 2011

Lots of pockets and cracks to some ledges which can be tricky!

Shared start with Argentina's Delight and Mother Butterfly. Easy climbing at 6b/6c leads to the cruxy 2-3m before the anchors. Hope you like slopey pinches! Some argue these last moves are 7c.

A 6b roof on pockets leads to a nice rest before a blank face. Attempt the minuscule crimps to the anchors.
