One of the best 5.10 routes in the whole Front Range! Outer Space is truly an understatement. Even the bravest of climbers hesitate as they step out into the void on the crux pitch of this route. 300 feet of air appear suddenly beneath your feet as you turn a corner high above the ground! The climbing is engaging, pumpy, and incredibly exposed. If you’re climbing the 5.10 grade, this route shouldn’t be missed.

A very quick approach leads to the base of the Bastille formation where other classics such as The Bastille Crack can be found. The first two pitches of this Eldorado Classic Climb are the same as The Bastille Crack. Pitches three and four are radically different and become very steep requiring a combination of stemming, laybacking, jamming, and pure balance.

The views of Redgarden Wall are outstanding and it’s easy to see many other climbing parties on the Wind Tower. The views from the top are worth the difficult climbing!
