Access Issue: (1) Weather Wall, Yellow Wall, & all the crags north of Twin Sisters are CLOSED. (2) No trash cans. (3) Highlining temporary ban in place for CIRO and CRSP Details

(1) The area, crags, and routes just north of the Twin Sisters are on private land and the landowner recently posted no trespassing notices at the gated road/trail to the area. Any access of these areas and routes is trespassing. The area was closed by the landowner due to trespassing, illegal camping, fires & trash, and disregard of owner's privacy.
Please be respectful of the land owner's wishes and do not climb or hike here until further notice. This includes White Lightning, Skinner Roof, Weather Wall, Yellow Wall, Larry's Annihilation, Needle Rock, Mississippi Fred's, and Secret Tom's. Park officials and CRAG are working to regain access to this valuable climbing resource. Be patient and check back for updates.

Access Issue: The Twin Sisters formations are off-limits to climbing. Details

The Twin Sisters formations are off-limits to climbing: The Idaho Historical Society has deemed that climbing interferes with the "Historical Viewshed" of the California Trail Corridor and has lobbied successfully with the Idaho State Parks to make climbing illegal on the Twin Sisters. The Access Fund has unsuccessfully negotiated restoration of climbing on the Sisters.

Bolts have been removed as a result of this decision (including descent anchors). Those that remain, if any, are undoubtedly outdated and dangerous.

Description

Note: This description is for the historical record only. All information contained within is likely outdated and inaccurate. Many, if not all, bolts have been removed from the Twin Sisters formations and climbing on them is illegal. Do not attempt to climb these routes for your own safety and compliance with the law!

North Twin Sister is the taller of the two siblings and is also host to far more climbing - including many long, lost City classics. Easy scrambling routes breach its slabby southern aspect; harder, single pitch climbs depart from a ramp along the east by southeastern flank; and longer, more adventurous routes weave up through interesting features and ominous roof systems on the eastern and northeastern side.

Sadly this formation has been closed to climbing for some time now.

I suspect that some anchors have been chopped, others have become dangerously outdated, and that descent from the top is problematic.

Getting There

Park near the Sisters campsites and find a vague trail that has fallen into disuse that leads up towards the southeastern toe of the formation. From here scramble along the base of the wall in the direction of your chosen climb.
