Moonstone Beach is Eureka/Arcata's easiest access climbing area. The good quality sandstone and greenstone boulders and cliffs, combined with soft sand landings under most of the boulders, make this a favorite for both the "The-sun's-out-class-can-wait" and the after work crowd. From the parking area there are four main areas with clusters of problems and routes. The rock dries quickly after storms and is climbable all year 'round but it can be foggy in the summer and days of rain in the winter. A rope bag or tarp is recommended when pulling your rope to keep it out of the sand. Moonstone is also THE place to meet partners for other local adventures.

Moonstone Trivia:
#1 Many of the moderate topropes were pioneered in the 60's or earlier by Andy Montgomery, a minister from Arcata who trained on a wall he built inside the bell tower of his church.

#2 The Moonstone outdoor clothing company was started by the beach caretaker in a tin-can trailer on this beach.

Getting There 

Take Highway 101 north from Arcata, exit at Westhaven Drive(just north of Clam Beach), take a left under 101 and left back south and take the first right to the beach.

A guidebook is available at outdoor shops in Arcata and Eureka.


Camping can be found just south at Clam Beach or 15 minutes north at Patrick's Point State Park.

The route starts on the face between Urchin and Assembly Line. Climb straight up to the roof. It would be wise to rest under the roof because the crux is directly above and requires a lot of strength and endurance. Grab the horn sticking out to the left, and the sideways jug above that before working your way left to a 3 finger pocket and a crimp. Smear your way up and dino to a good jug up and to the left. From there, work your way back to the right across the face and up over the ledge to top ...[more]   Browse More Classics in California

The Holladay-Hatfield is still there, although the hangerless bolts have been looking pretty bad for 15 years. The trees and shrubs seem to have overtaken the route.

I'm trying to figure out where this climb is exactly. The guidebook has "Holladay Traverse" as 5.10 and "2 old hangerless bolts, shrub belay, 35 feet" but the guide shows that one on the south side of North Rock... Any clarification?

what is the policy on bolting at moonstone? I've heard that it's prohibited on karen rock. can anyone confirm that? some of those lines would be rad leads.. What about bolting any other lines at north rocks or anywhere near that?

Many of the lines on Karen Rock would make for some nice leads but due to the wide variety of beach users and complaints of desecration by local tribes, climbers have only replaced existing bolts for safety. The management plan for the beach suggested several scenarios at Moonstone that included removing all bolts or not replacing the old ones. A decision was not issued as the tribes did not pursue the removal of the bolts BUT the issue could be revisited at any time, so climbers have not pushed the issue of new bolts. We are fortunate that climbing is allowed at all at Moonstone, especially with the tribal issues. Also, pretty much all of the routes have been free soloed or led with (sometimes iffy) gear, so "leads" have been established and can be led in the style of the original lead ascents....

The biggest impact on the beach is all the annoying dogs and their shite!
