the approach from the trail can be hard to find especially in spring if things are growing. Plan on a two hour approach at least, not very fun. The arrowhead point route itself is not good enough to warrant the trudge up there, but if you do the arowhead arete as well, I think it is well worth it. The arrowhead arete may only be 5.8 , not 5.9 . The arrowhead point is only 5.6 .
It's possible to top out and get to the yosemite falls trail The way is pretty obvious with some 4th class and lots of bushwhacking, at least not worse than the aproach and the descent described in the supertaco guidebook plus you have a nice view and a kind of a summit.
This is an area page, somebody please add some climbs under this! I've done Arrowhead Arete but don't remember enough to add a useful description. We first climbed Arrowhead Pinnacle, and I'd recommend starting this way.
