Bat caves are a great day trip. There are enough routes there to make a few trips worth it. Anywhere from .7 - .12, trad, sport & mixed. Bring enough pads and even the bouldering is good. Check out the caves too.
Baker Rocks, on the Mt. Baker Hwy are good, but need use. Not enough traffic to keep mossy sport climbs clean. There are a few in the .11 - .12 range that are dry almost all of the time and are right by the road. Worth visiting & it's quick. Can get good spring/summer riding in near the ski area, and clip bolts on the way home. Have fun!!
