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.

Beautiful country, but conditions are pretty miserable right now between the mud and snow.

Started out on Green Mountain Trail. Very steep climb during the first mile. Merged left onto Summit Loop. North side of Summit Loop was muddy and a hit rocky for running. Then merged onto Rooney Trail. This was the best part of the trail for running. Only a few muddy spots to deal with, that you could jump across.

Trial is about 90% dry now!

first time at this trail head and randomly got myself on box o rocks. nice elevation gain but the trails are narrow one way so watch out for bikers. no shade, but that was fine as I wanted to enjoy the sun. lots of highway noise at the beginning but it does down as you go further. in all, it's convenient trail if you don't want to fight traffic and just want to get out.

Trek as long or short as you want. Looks easy, but it's not!

Lots of trails to choose from and lots of sun. Had meant to do the Zorro trail on my off day for an easy run but stumbled upon these trails. Pleasant surprise. Will definitely be going back to venture some of the tracks I didn't cover. Lots of bikes but this me some time to rest on some of the steeper inclines. Great space

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.
