Hike contains poison oak on the trail and there was no water in the stream when we went there in the winter. Campground was closed as well. Wouldn't be back.

Fun little hike. Weather was great and lots of water. Only thing to bear in mind is a nasty patch of poison oak at about ~1 mile so avoid wearing shorts.

This trail to the campsite is 2.7 miles one way from the redbox parking lot and it's mainly downhill, not a bad way to start if you're packing heavy, it starts off open but once you hit the Gabrielino trail it's pretty shaded, only bad thing about the trail are the damn mosquitoes and gnats! You're walking on the trail and you have your own entourage of 50 buzzing around your face, lol. Once you get to what I like to call 'the wtf' section, you have 3 options, left/middle/right. The far left access road takes you to the campsite as well but it's a little bit longer in distance, completely exposed with a few areas of shade but it's a gradual incline, good to take on the way back if you don't want to come back on the trail which will be all uphill. The middle is the Gabrielino Trail and that takes you to camp as well, you'll see a burned down cabin cabin and an abandoned campsite. The right takes you back to the top, it comes out at the smelly restrooms on the parking lot. It looks like the main trail hasn't been maintained in a while, there's overgrown poison oak over the trail so wear long sleeves and pants. There's little to no water in the creek, there's a section on the trail where there's a small amount of running water on the creek bed where you might be able to filter water from if needed, other than that there's a few puddles of stagnant water which are the cause for the annoying bugs. The campsite itself is very nice and big, there's 4 sites to camp in, each with their own tables and fire ring ( don't forget your fire permit ). The pit toilets haven't been maintained either and, when we were there, there was no toilet paper and a few toilets were very soiled. All in all it was a decent experience, the bugs really killed it for me though.


There's no trash cans there, the previous people that were there left a hefty bag full of trash in the restrooms, that's ridiculous! Don't be that ignorant and disrespectful to Mother Nature, the animals don't need to be eating your trash.

Campground is pretty open and seems well used. There are bathrooms stocked with toilet paper and black widows.

There was very little water to be found. A few stagnate pools breeding a fair number of mosquitoes and the like. With a small fire they weren't too bothersome.

The campground does have fire rings though fire permits are of course required.

Explore the area because there are a lot of old roads and structures nearby. Tall picnic tables all over the campgrounds and small trails leading to more secluded spots from the main ones.
