From I-25, take 6th Ave. west. Drive approximately 6 miles to Kipling. Take Kipling south for 2 miles before taking a right on Alameda. Stay on Alameda for 3 miles until you see a parking area on the right. This is the "Florida" trailhead because it is across the street from where Florida Drive exits onto Alameda Pkwy. About 1000 ft farther down the road is the "Utah" trailhead. Directions for this hike begin at the south end of the Florida trailhead. ... If you're coming from another part of town, google the directions for Green Mountain Open Space. From Denver take the 70 for about 9 miles to C470-East exit (exit 260). Go about 2 miles on C470 East and take the Alameda Parkway exit. Turn right onto Alameda Parkway, then take your first right onto Rooney Road. Go about 1.5 miles and the trail head parking lot will be on your right.

Great park where you can pick and choose trails, difficulty, and length. No shade coverage anywhere so very hot and exposed.

Great leg workout mostly uphill. A lot of bikers but courteous on the path. Beware no shade, bring lots of water. No resting spots for breaks. Maps are poorly marked but we enjoyed the run!

Started the trail around 930am on a Wednesday. Very little traffic, maybe 10-15 people passed by on foot or bikes.

Perfect! Trails can get super busy as the day goes by. Most using the trails are courteous but there are plenty of mountain bikers who whiz past you so be alert.

I live on this mountain and enjoy hiking here. It is busy during the warmer months, and as others point out, many bikers don’t share the path or watch their speed which is annoying but hey, driving 6th Avenue has the same issue so you get used to it. Watch for rattle snakes!

Easy, enjoyable hike. Great for a newbie to the area getting used to a little elevation (like me!) and still wanting some nice views without traveling too far. Saw some cool birds and a coyote.

This trail was a lot of fun to run. The only suggestion I have is to be familiar with the trails before you head up the mountain. The kiosk at the trailhead has a trail map, but it isn't very specific and doesn't show distances per trail. Being a first-time on the mountain, I ended up talking to several friendly trail runners who gladly helped me out. Super nice weather!

shows signs of a lot of people. too much bike activity with riders thinking mud is fun with no respect for the trail damage.

This is a very nice trail extremely close to downtown Denver. My girlfriend and I hiked the largest loop possible starting from the lot west of C470. We started off going up the step incline to the left by the large rock outcropping... this may have been out first mistake. This path is nice and wide but a straight incline for well over a mile. We really liked all the different trail options and for being just an open space with no trees it was actually very pretty. Our only complaints about the trail is the different trail options aren't defined very well, gender the reason we took the largest loop, evening ending up on Alameda at ones point. The other HUGE complaint is this trail is an excellent mountain biking trail. We must have yielded to no less than 150 bikes in our 2:45 of hiking, and in some sections they are flying well over 20/30 mph.

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 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.

One of my favorite hiking areas close to Denver. Decent opportunity for elevation gain (especially if you take the fire road from the West side - that seems pretty steep). You can connect numerous trails into the distance you want . . . and loop and loop and loop.

Popular with mountain bikers, but 9/10 of them are extremely polite. 1/10 bikers should be reminded that they are supposed to yield to hikers, equestrians, deer, porcupines, voles . . . you get the idea.

Note -- the 3,000' plus elevation gain is if you do every single trail (thus descend and climb). From trailhead to highest point is about 930' or so.

Super easy trail. Was the first trail I did so I didn't realize how many other super cool trails were out there. Lots of dogs and kids and open space. Nice little morning outing

I particularly like hiking here in spring, when it is less crowded.
