Lyme disease rock is a pleasant little crag worth checking out . There are moderate bolted lead routes as well as fun top ropes . There are also stiffer 5.11 and 5.12 leads . When Indian Rock or Castle Rock is jammed with people , Lyme disease rock will often be empty .
Proceed to the Indian Rock parking area . Make a quick right on the skyline trail and follow it for approx. 10 minutes . You will see the top of Lyme disease rock on the left hand side . Skirt to the right and down to get to the base of the crag . There is easy TR access .
