Two rock climbers were rescued in Eldorado Canyon State Park south of Boulder on Saturday evening after becoming stuck.

Boulder County rescue crews were called just before 8 p.m. by two climbers who were stuck on the top pitch of the T-2 climb located on Tower Two of the Redgarden Wall.

The 22-year-old and 20-year-old male climbers, both from Boulder, began climbing at 2 p.m., but moved slower than expected, Boulder County sheriff’s deputies said.

“By the time they recognized the need to bail from the route, it was becoming dark,” deputies said in a news release. “The climbers did not feel it would be safe for them to rappel down, especially given they did not have headlamps. As a result, they made the wise decision to call for rescue.”

Rescuers were able to find the stranded climbers using spotlights and a team was sent to help them get back to the trailhead. Deputies said a team from Rocky Mountain Rescue Group climbed up the East Slabs to the top of Tower Two.

Rescuers then rappelled down to the stuck climbers and assisted them up to the top of the climb. The climbers were then assisted down the East Slabs using several rappels. Both climbers were able to walk out to the trailhead, with the second climber arriving back at the parking lot at 6:45 a.m., Sunday. Deputies said neither climber required medical attention.

The rescue took approximately 11 hours, deputies said.
