Dierkes Lake This versatile climbing area is located about 2 hours from Boise on the outskirts of Twin Falls. It offers steep sport climbs, traditional crack climbs and a plentitude of bouldering. The rock is basalt and it is typically steep and well featured. One Dierkes climber told me that a particularly steep sport route at Dierkes has "the biggest holds on Earth". The best time to climb at Dierkes is spring or fall but it is possible to climb year round if you don't mind scorching summer heat and frigid winter cold. To reach Dierkes Lake from Boise, take I-84 east to the Twin Falls exit. Take the exit, which will put you on Blue Lakes Blvd, and drive into Twin Falls. Proceed on Blue Lakes Blvd to its intersection with Falls Ave and then turn left. Proceed on Falls Ave for about 3 miles and then turn left on Champlin Rd. Proceed on Champlin Rd to the Shoshone Falls/ Dierkes Lake Park Complex where you will be charged a small entrance fee. For more information about Dierkes Lake and other Twin Falls area crags, refer to Mark Weber's guidebook, "Basalt Climbs of South-Central Idaho" and "Rock and Ice Magazine", issue #56.
