Do you want to climb somewhere like Duncan's but without the crowds or any fixed anchors? Well, then Marina Ridge is for you.

Marina Ridge was initially explored and developed by John Gill and others in the 1970s, primarily as a bouldering destination, with the Sunshine Boulder being the most popular. Bob Horan has documented some of this in his guidebooks; however, there is little to no information on the toproping/trad climbing available on the actual ridge line. I attempted to use historical names when they were available, but many of the routes have no historical names associated with them. Because of this, they are labeled with names and grades that my climbing partners and I have come to reference them by. If anyone has information regarding the history, I will be happy to update the routes accordingly.

Marina Ridge, for now, has no fixed anchors of any kind. All of the toproping must be done using trad anchors, or by slinging trees on the top of the ridge. Luckily, there are many to choose from.

Getting There 

Park at the pulloff just to the south of Dixon Dam, and follow an access trail south along the top of the ridge for 10 minutes. The trail will pass a house on the left before reaching the top of the Main Wall. Rappel off the top, or take a trail down to the base. The descent trail contours around the north side of the formation. This is not the quickest way to reach the Sunshine Boulder (which is several hundred yards further south of the main wall), but it is the only way that avoids cutting through private land.

Mountain Lion Alert 

Note, mountain lions have been seen in the area. Pay attention to small children and pets while out and about.

Went to scope the area out on 9/10/17 and saw a mountain lion about 50 feet south of the main wall.
