Like Bonita Canyon Falls in the San Gabriels, the Vanalden Caves on the south edge of the San Fernando Valley is an example of how something that seems too good to be true is just that. In this case, the destination is a large sandstone cave, with several holes in the top that allow looking in from above, only a short drive from the Valley. The catch: graffiti, trash, and lots of it. Still, the trail makes a nice excursion and allows San Fernando Valley hikers to see some interesting geology, even if it’s not exactly as nature intended it. The Vanalden Trail also serves as an access point to longer hikes on Dirt Mulholland and the northern end of Topanga State Park.
From the end of Vanalden, head south on the single-track trail. At 0.2 miles, head left at the fork (the right trail heads up to the dirt road.) Follow the trail around the side of the ridge, and descend into a wooded area. The trail drops to a creek bed and continues east, but you will turn right and head south into a small canyon. A short walk along the left side of the creek bed brings you to the cave.
The cave is large, and you can see the sky through some holes in its ceiling. If you are feeling brave, you can climb a narrow trail along the right side of the cave, to its roof. The trail is short and easy to follow, but it also leads along the very edge of a 20-foot drop, so be careful.
On top of the cave, you can see through the holes–again being careful–providing an interesting perspective. A few informal trails lead up to Dirt Mulholland if you want to extend your hike. Despite the graffiti and trash, the uniqueness of the geology and the convenient location make this a good hike to know about.
