Climbing guidebook

Several possibilities exist inside the cave as the rock is solid and good. Climbing routes start with 6b. Be careful of the 2 hidden blocks in the water – they’ll make a nasty landing. The first underwater block is near the cave entry on the left – the other one on the right inside the cave. Test the depth with your paddle before climbing. The wall on the left offers very easy short climbing routes. The steep wall with very long stalactites offer interesting and hard potential.
