Twin Caves is a classic, very popular crag, thanks in part to an ample variety in routes, grades, and climbing styles, and a short approach. This also means it can get quite busy. There are indeed two caves—though, clearly, they are not twins: the large cave on the left, with its impressive stalactites, is the star; the smaller cave on the right is just an accessory.
On the left, easier slabby climbing on pockets, crimps, and grades mainly from 5c+ to 6b. Some steeper technical climbs to the corner of the cave are harder, around 6b–6c. The main cave offers world-class, very steep athletic climbing on impressive tufa formations, tufa curtains, and holes. If you climb 7b and up,
you will be ecstatic. The drawback is that there are very few routes from 6c–7b. Nearly all routes were equipped through the AOS Project in 2013.
A single 70m rope + 17 QDs.
Ideal for winter, or on cloudy spring and fall days The cave is good on rainy days or late on hot days.
__Shade (Exposure: S)__
Almost never. In warmer months, though, there is some shade inside the caves after about 15:00.
So-so. A short but steep path and limited good areas.
