Officially this is called Los Robles Trail West. But this popular section is known to mountain bikers as space mountain. Great flowing downhill with lots of twisty turns, most of them with generous berms. The sandy soil drains nicely making this is one of the few good area trails after a rain.

       This is a fun down hill portion of the Los Robles trail system. Watch out for riders and hikers coming up. I've never ridden up, I always go up Rosewood and then take Lynn back to my car (parked near Stagecoach Inn). I don't know why people pedal up Space Mountain. If you park at the bottom of Space, you can take Lynn up to Rosewood for an easier climb and an all around nice loop ride.

       Fun ride if you just want to stay in town. It can get busy on the weekends, lots of riders and some hikers so you need to watch your speed going around blind turns. The last few times I went there I encountered groups of older riders who are not friendly and all they can talk about (loud enough for everyone to hear) is how many people there are on the trail today. Fun jumps at the bottom.

       I don't know why people ride up Space Mountain. I get it, there's a parking lot at the bottom. But you can ride up Lynn and go up Rosewood or just park in the park's parking lot across the street from Rosewood trailhead and ride up Rosewood from there and then take Lynn back to your car after you come down Space Mtn. It's getting pretty ridiculous how crowded it is. And I see way too many people riding up with headphones in! I always wear a bell going dh, which everyone should do, but when idiots ride up with headphones in close calls are inevitable.
      Ride safe, have fun. Yhee!

       I like going up space mountain because its a fun technical climb. But yeah, totally agree about the headphones, don't wear headphones while riding on a busy trail!

       Space Mountain is a easier climb than Rosewood (at least after the bottom steeper sections), that's why people go up it instead. Plus it makes for a great ride to go up space/down rosewood and then back up rosewood/down space or vice versa. I do agree with the headphones. Use a bell, and if you are gonna ride with music, only ride with one earbud in.

       That was my first and only impression of Space Mtn, that it'd be a lot better experience if it was a one directional flow trail. The uphill traffic ruins the experience. You know, in places like Bend Or, they build bypass trail sections that uphill traffic can use to avoid these kind of issues. Like in the curvy or fast DH sections, a bypass exists. They work very well. With an increased amount of users on the trails, some rethinking of how we do things is needed. The bypass trails with single directional flow is the best solution especially on the faster downhill flow trails. What do you think?

       Ebikes are allowed on all trails in Los Robles Open Space. Even the rangers use ebikes and I’ve personally spoken to two rangers and they said it’s fine. Trailforks needs to update this information as tons of trails are open to ebikes in Ventura and Los Angeles counties where Trailforks currently says otherwise.

       Started at Los Robles West and went up. Los Robles has a couple sections where you will need to hike the bike up. Once we connected to space mountain, it was a fun decent. I took a new guy with me and he had a lot of fun. The trail was manageable For his skill level

       This is a great trail in either direction. I like to ride up it because I can. It’s recently been rerouted where it crosses Ventu Park road. The new section is nicely cut in, but the surface is still a bit soft. It now bypasses the very steep, chunky, rutted, loose section that was just south of Ventu Park Rd. I was rarely able to clear the very top, but it was a fun challenge. The reroute is moderately steep to climb, but nowhere near as technical.
