Fun, intermediate mountain bike ride about 20 minutes west of Denver, near Lakewood, Colorado. This trail is fairly easy with a good climb and intermediate descents. Also popular with hikers. Please share the trails respectfully. Not all of the trails and junctions are well marked, so be careful not to get lost and bring the map with you if you can.

From the 470 side it's a good short vertical gain of about 700 feet in 1.1 miles great for repeats especially time is limited.

Very boring hike. There are some great views here and there, but the rest if very boring. Zero shade - I mean zero. Not even at the trail heads. No picnic tables, no water sources and poorly marked trails. A lot of mountain bikers seem to be enjoying the terrain - not too steep and some great single track. I would not recommend this for a hike. I needed to get a 20 miler in with my son for his Hiking Merit Badge and the 20.8 mile loop looked great online - but you have to watch the route closely on the app to make sure you don't miss the turns due to the poor marking.

Pee before you hike or at least don't guzzle water. There's no place to drop trou without a biker zipping up on you or in plain view of pretty much anyone on your side of the mountain. ;) It's pretty but hot! Absolutely no shade. Lots of routes to choose from.

No shade, which was not the most pleasant in the summer, but beautiful scenic views and wildflowers. I'm pretty clumsy, so my foot slipped on the loose rubble coming down, so be sure to wear shoes with good traction.

I live down the street Avd it's great exercise. I wish the trails were marked better as far as distance traveled. It seems only Green Mountain Trail starting on the west side is marked.
