This park has three parking areas. The loop is the same from all. From any trailhead, begin a clockwise loop in the park. On the south-east sides of the park, this loop maintains fairly constant elevation as it winds around the base of Green mountain. On the north west side of the mountain, a jeep road will take you to the top. On top, follow the jeep road past the radio towers, and back onto singletrack on the south east leg of the loop. Descend this singletrack, and finish the loop back to your car.

Q: How long

    This is my Daily Grind. I can ride to it from my house. Been riding it over 25 years now. Wonderful training loop. An intermediate rider will complete in about an hour with 45 minutes in training zone.

    It's a Dirt/Rock trail. It would be an easy trail if it weren't for the loose rollers all over the trail. That makes for some technical staring to stay on the hard. Clockways has a LONG HARD 15% climb. Counter-Clockways has that same thing as a decent, so, I like Counter from the Alameda Pkw lot. There is a steep climb out of that lot and a gradual one. I like the gradual one that heads off slightly left 100 feet from the trailhead.

    Max pitch on the way up (counterclockwise) is 15% for about 100M. Watch out for the 12% 200M grade around turn 3. Again, it wouldn't be that hard, if it weren't for the fact that there is lot's of loose rollers. Get caught in those while cranking and you're going to either hammer it out or jump off.

    Our backyard trail. Access from Alameda across from the dog park at Solterra. Travel West toward 470 and North to climb. It's open, wide and deceivingly long climb to the top is rewarded with tight, occasionally steep descents and forever Denver views. Nothing technical, lots of friendly people; hikers, dog walkers, runners and mtb'ers all living in harmony on this well covered, local favorite.

    No trees, ride early or late. Very hot at noon. Nice trail otherwise.

    Still pretty nooby, so this was a nice warm up trail super close to where I live (SE Golden). Biked here from my house, pretty good way to get used to the altitude. Decent amount of weekday joggers and riders, but not too bad.

    Being a flat-lander I found this trail-system to be a good change from what I was used to, long steady climbs, circle the peak, then a long fast descent. The views of Denver and the surrounding area make the ride to the top more than worth it. I'll definitely be back in the future and connect some of the adjacent trails as well.

    A nice change of pace in town to get a quick fix. But fairly boring (for me).

    System of easy to moderate trails within the Denver metro area. Great place to get your climbing legs for the rest of the state.

    Fun trail with a little bit of technical stuff here and there to develop skills for those of us who are still learning. The "Jeep Road" on the NW side, kicks up to 24% grade at one point and is a butt kicker if you are not in good shape. I was not the only one getting off my bike going up. In fact, all but one person I saw did. Biggest issue is that if you ride it on weekends it's really crowded with hikers etc.

    I think this trail could be great riding with shade, but it's completely exposed to the sun. Hit it in the fall. It has a lot of uphill, but the downhills are some nice cruising. Be sure to ride to the summit for views.

    This is always busy! even when I was midweek on a windy day, the parking lot was full. I would recommend going up the big hill right from the parking lot and get on top as soon as you can. This way is the funnest because you get a longer downhill. The downhill was a fun cruiser where you could really get some speed up. Nothing technical. A great afterwork ride or a family/wife ride.

    Initial dirt road climb felt long to this out of shape dude. After the first climb it has some fun switch backs and more rolling sections.

    Parked on the west side and went clockwise for 1.5miles nothing but uphill. Ouch

    Nice trail network that is easy to get to. The southwest side offers some rolling double track that is great for the novice with some short rocky sections. More advanced riders can work their way to higher elevation, choosing from a number of climbs, from smooth jeep road to rockier single/double track. No shade to speak of though.

    Got on the trail at 6:00 and rode the loop to the top and was done by 8:30. For an inexperienced rider such as myself, these rolling hills provided a fun ride that did not tire me out.

    Green Mountain is a decent trail configuration. On the West and Northwest side of the mountain is the best singletrack. But its a small little mountain worth exploring if you live in the Front Range. There Are alot of fun smooth single track all over. Although they are not very long but worth day of exploring the whole place.

    Granted there are better trails along the front range, but if you are looking to test your legs climbing, this is a great trail for that. The climb up the jeep road is a grind. There are plenty of off shoots that you can take that will give you some variety. Overall a good trail with good views at the top.

    I don't even know why this trail is listed in here. If you don't live in one of the surrounding neighborhoods and can ride from your house, don't bother coming here. There are much better rides around. That being said, I'm glad I have this trail next to my house. It is a great training ride with lots of different loops to keep it interesting. You can do a quick 45 minute ride or hook up Dakota Ridge and Mathew Winters for long rides. Fun on a single speed.

    All I can say, it's a good training ride. I would prefer fast and flowwy trails, but there are not many of those on the front range. It's clear most of the winter, so when other trails are closed, it's usually available. A lot of climbing for a little bit of downhill. Again, great for training, but so far it's my least favorite trail in the Denver area.

    Great training ride. Not much variation in the type of terrain. Hard pack mostly, rocky in parts with some rock gardens. Depending on the trail there are some good flowing sections or just straight up (seems to be a trend on the front range). I started at the Rooney parking lot and rode essentially clockwise, taking the Rooney Valley trail (keeping left at forks). This is ALL up from this direction, gain is about 1200 ft. Then I took the main road along the top, down Hayden, and around Green Mtn. trail. Mostly single track other than the road. I had fun.

    The perfect place to hone your climbing skills without having to deal with technical challenges! If this not your idea of a fun ride, just go to Dakota Ridge or Apex nearby. You can turn this into a 20 mile, half day ride if you do all of the trails. Not the place to be if you prefer to avoid the crowds. There are definitely parks in the area with better scenery, which in turn are more desirable places to be during the hot months.
