COSF Highlights CONEJO OPEN SPACE FOUNDATION • Little Sandstone Trail passes through what could be some of the most beautiful sandstone rock formations in the county • The "Mini Tripeaks" on Little Sandstone Trail is a great place to explore the rock formations, and to stop for a snack or lunch • Hidden Meadow Trail is really fun on a mountain bike • Hidden Meadow Trail has a great wildflower display in the spring • The Hidden Meadow Trail is a segment of the 2026 Conejo Open Space Challenge (https://cosf.org/challenge; colored pink on the map below). Description The route is only 3.8 miles long in total, but has a lot of climbing for its length because Little Sandstone Trail is so steep in sections. That said, it's well worth the hike because it passes through some amazingly beautiful sandstone structures, and the higher you go, the better it gets, and the views too! Because it's steep and very rugged, it's not appropriate for mountain biking. Hidden Meadow trail is much more mellow in comparison. It's a little steep at the beginning, perhaps for the first 50', but after that the slopes are gentle. With all the twists and turns, it's tons of fun on a mountain bike. Looking north, you see the rocky hills that Little Sandstone Trail climbs though.
