Space Invaders

5.12a, Trad, TR, 40 ft,  Avg: 4 from 3 votes
FA: Chris Falkenstein
California > Yosemite NP > Yosemite Valley > Royal Arches Area > Royal Arches Boulder…
Access Issue: Yosemite National Park climbing closures and conditions Details


Steep and intimidating even on toprope, the Space Invader starts at 4" and only gets wider. Tie in and get ready to struggle, whether you choose to jam it or layback.


Just west of the Ahwahnee parking lot (just before the road splits into the lot), approximately 50' north, directly into the boulders. You can see the top of the crack (6" crack) from the road.


The anchor is one good bolt and one not-so-good bolt. A couple directionals in the 4-5" range are highly recommended, as the route overhangs 45 degrees. Be careful setting up the TR, it is exposed and slippery.

If leading, you might need/want 2 each 4-5". One 6" piece will do.

[Hide Comment] It's Space Invaders, with an 's' on the end, like the video game. Not Space Invader. Nov 18, 2010

[Hide Comment] We replaced the questionable bolt in the anchor with a nice shiny stainless bolt this past spring (May 2017). All bomber and ready for you to hang all over it on TR! Oct 10, 2017
