Mountain Biking Rhyolite Bike Park

***   Add a review
#348 of 1,362 mountain bike trails in Colorado

This is a 1 mile bike park/pump track. The climb is straight and very gradual and the downhill has banked corners with a few berms thrown in. There is nothing technical about the singletrack at all, but it is fun for a few laps.

The trail is a one-way loop and the direction of travel is clockwise.

There are no hikers allowed so you can go nuts on the downhill without fear of running over anyone coming up.

    Excellent BMX or downhill spot. The trails are all clearly marked and easy to find. There are green, blue and double black trails. There is a pump track which also features green, blue and black lines. The downhill section is fairly short but still fun. It gets super narrow at the end of the trail.

    Rhyolite bike park keeps getting better! There is a team of volunteers as well as great community support from Castle Rock Bike & Ski and the 6202 cycling club. As a result the community makes steady and incremental progress so each year the downhill lines get smoother, burms get dialed in and more people enjoy this place. They even have a youth downhill race in the fall ages (5-17). This year the new sessions park arrived with 3 very decent lines that will improve as they settle in. This is a great place for kids to develop solid skills and for the skillful to have a blast. Every skill level has something to enjoy here and if you don't want to jump, then take a few laps around the top of quarry mesa. I'm excited to have it in my back yard and I invite you to try it out soon.

    For a place like Castle Rock, CO to have it's own downhill park...well that's pretty progressive of them. Although this is not the most amazing park it does have a lot of potential as long as people are willing to raise it to that bar. there is a map at the bottom of the hill that explains how the trail system works and the signs at the top are simple to understand so you don't end up on the wrong trail. The initial uphill to the tracks is pretty easy so beginners should not be worried. Once at the top just follow the signs to the difficulty of the trail you want to ride. The beginner trail is very straight forward with some ok downhill and a few pump sections with turns. The intermediate area has slightly more aggressive downhill sections with a few jumps mixed in (beginners have no fear they are simple jumps) with some nice banking turns. Here's where this track falls a bit short of it's goal. The bridge between intermediate and difficult is very big. You go from very simple jumps on the intermediate system to much larger jumps on the difficult area (granted they mark this area with double black). All in all if you want to try something different this is a fun place to get a few runs in. As this area is expanded I think it could be something special for the area.

    There's a mild climb up to a couple non-technical downhill runs. Nothing to get excited about as of now, but it looks like there's big plans for numerous skills development areas. May be more wirth the trip when complete.
