Swim Fin is a popular rock due to its accessibility and the high concentration of moderate climbs in this immediate area. Shade can usually be found on one side of the rock, depending on time of day and season. Certainly a full day can be had in this area, though some of it may be spent waiting in line.

The most recommendable route on Swim Fin is Ego Donor(5.9), a clip-up on the back side, facing Blazing Fin. It is sustained and honest-to-goodness 5.9!

Getting There

Driving up the Catalina Highway, park at Windy Point (mp 14.3). From the uphill end of the parking lot, opposite the overlook, cross the highway to the guardrail. An obvious trail leads off from the upper end of the guard rail.

Hike this trail out the ridge away from the highway. As you near the end of the ridge (couple hundred yards), find a trail that drops sharply down the right side along a small cliff. It may take some looking to find the right spot, but once you do, it will be obvious. It is well travelled.

Continuing down this trail, you will approach Nancy's Thumb, a large pinnacle with an obvious crack on the north side. Follow a trail off to the right from Nancy's Thumb. It will lead through some dense brush and out onto a large, open slab. Swim Fin is the rock to your left. There are climbs on both the front and back sides. Allow seven minutes for the approach.

there's a really good 5.8 gear route that starts just left of ego donor on swim fin and follows a crack system up and left and into a chimney. finish on the same anchors as ego donor but don't give in to the temptation of clipping any bolts, no matter how good they may look. there's bomber pro all the way up the route aside from a little runout on easy ground right after the fist crack, even back in the chimney near the end of the route.

this is a perfect climb to develop trad sense, especially where route finding is concerned (the pro does take some finding higher on the route). for me it was great practice and great fun.

On the back side of Swim Fin, you can find Blazing Fin. Blazing fin is an easily accessible crag with a variety of nice moderate routes on both the east and west faces. There are both bolted routes and gear routes, so there is a little something for everyone. There are several routes such as Makin Muffins (5.7) and Ego Donor (5.9) where you can lead one route and then top rope another from the same chains. You can find a shaded route here most of the time. Rather than filling up the area list with small areas, I am going to post routes on both "fins" here. Sep 27, 2004
