The Sisters Bouldering area is located northeast of Sisters, Oregon on Wilt Road. The area offers excellent beginner to expert routes on volcanic rock, which range from simple boulder problems to difficult 5.10+ top-rope climbs. The East Fortress is a line of boulders that extends to the north and to the right of the Front Gates. This is a great place to stop if you're on your way to Smith Rock and are curious of other explorations. Be respectful to nearby property owners, and keep in mind that there are fire restrictions during the summer and fall months.
