Park at the Miller Activity Center parking lot (or start on sidewalk just off the Plum Creek Parkway entrance) and join the trail at the base of the "mini incline" stairs (200 steps to the top of the hill).
The trail continues past the steps and the singletrack starts. Stay to the right as the first left will take you to the top of the mini incline. Follow the singletrack as it twists and winds around the hills of this 220 acre Town Park.
Don't forget to stop and look around as the views from the tops of the hills are impressive and provide a great overlook to Castle Rock and the surroundings area.
The trail has very few straight sections, so use caution on the blind corners when going up or down the switchbacks. The trail has some short but steep climbs but nothing that a fit, regular mountain biker can't power up. The reward is worth it for the views and the fun and quick downhills.
There are few trail intersections, so getting lost on this trail will be tough. In the future, a shortcut will be added at the north end of the park to cross over Wolfensberger to access Ridgeline Open Space trails.
Great trail system for in town. The trail is all singletrack and is cut in such that the moderate climbs are never difficult and the pay off is an abundance of flowy riding. Joined up with Ridgeline Open Space, this is a real gem. Great job Castle Rock. I'll be back, but only on weekday mornings. If you have two steeds, leave your big, long travel bike at home.
| ThankEasy a pretty bike path. A little busy
| ThankThis is Ridgeline's rebel sibling. A great addition to Ridgeline and when combined, makes for a fine outing. Having the trail system up the road from where I live makes for many outings. The design of the MAC is an adrenaline shot Ridgeline lacks. You're going up or down with quick and exciting descents to boot. Not as busy as Ridgeline with the Hikers, Bikers, etc. The North side (nearest the Ridgeline connector bridge) is the quietest and most fun. All climbs and descents are quick though. Erosion is minimal but the trail needs to be respected during the Winter months.
| ThankFor a neighborhood trail, it is awesome. Some really fun sections, but nothing major, no massive climbs, no massive downhills.
| ThankSome of the best trails in Castle Rock. Short, but you can link to Ridgline for a longer ride.
| ThankSmooth rolling single track, short climbs, good trail for the beginner or someone looking for a quick easy ride
| ThankPretty average in every way (except tech, rather less than average in that regard), but better than other typical suburban open space parks in the area. I do like that some of the trail is narrower than other local offerings. The stretches in the ponderosas at the north end are particularly nice.
| ThankVery cool winding trails in and around the hills. Very little technical
| ThankThis trail system is a nice place to get some miles in after work. Nothing here is technical, but it is fun.
| ThankThis trail is a great single track. It has some steep climbs and very flowy down hill sections. There are some blind corners, so be careful when coming up on them. The trail consists of several loops that are well marked. If you need a longer ride you can always connect this with ridgeline open space. This trail is fairly easy and not very techneical. A beginner could easily do this as long as they are careful, but it is a narrow trail.
| ThankLove this trail! When you loop all 4 together it's about 7 miles. You can start at either end as all the trails connect. Punchy climbs, super fast single track, lots of switch backs as well as some technical rocky sections. I ride this trail several times per week before work.
| ThankThe new trail loops at the PSM Park are a very different ride from Ridgeline, just across the road. More switchbacks, whoop-de-doos (drainage berms) and punchier climbs. It's also shorter so a great way to get a quick 6 mile loop in after work.
| ThankI have only been riding for 3 summers, but I had a lot of fun with my $300 hardtail. I would not say this is advanced but absolutely not beginner. Had about 2 places that were just to steep for me. Overall the trail had good flow and I kept going just fine. Had to peddle but when you get your momentum up I didn't have to slow down much. A few rocks but avoidable. You are in the sun most of the time which gets a little hot but after our two weeks of rain it dried completely within 2 days. This is the kinda single track that I look forward to riding. Fun enough I'll go again for sure and hard enough to leave with a Great workout. I started from the parking lot of the Phillips Miller park. I kept right and ended up all the way around the top thru the zip line tour, then up to the top of the tallest zip line where the stairs are, about 7 miles when I was done. Watch the corners, some are pretty tight. There was no one there when I went about 6 in the afternoon but if there were people you would have to watch out racing around corners.
| ThankPump and Flow:
| ThankThis trail has had some heavy design money invested in it. Feels like an east coast clay track and Is built for max speed with minimum effort. XC riders will need to adjust to less pedaling and better descending feel the max speed here.
It's a great loop and once they add the connector to Ridgeline it will be even better. It's a pretty tight singletrack in most places but visibility is good, so that helps.
| Thank
