Attention dog owners: there are TONS of prairie dogs along this trail. Definitely super cool but my dog just wanted to chase after them! Great trail but I would only bring your dog if you know she won’t run after small mammals!

Love this trail. Perfect moderate run, I've hit it from all angles and just really enjoy it. Simple! Full sun, muddy, there can be snakes, otherwise dusty, and great view of the birds and notorious Nipple towards Longmont.

Nice easy trail run. Not too much mud today!

There are two main trailheads to access the Sage Loop - the easternmost lot has more room for parking (the best choice for RVers) and only trash cans; the westernmost lot is smaller, but has both trash cans and a pit toilet open for the mud season. The trail is fairly flat, with almost no shade, and is very easy to follow. Expect: pedestrians, runners, cyclists, dogs (off and on leash), and equestrians (who, for better or worse, are known for going at a full gallop around blind spots on this trail, endangering pedestrians. Keep your ears open for the grunting of a running horse approaching, and step off the trail to yield). Expect also high winds blowing in from the foothills, and the dust that they may carry.

I ran this in the summer initially north-to-south, connecting to additional trails on the south end. Like many other trails, there is almost no shade. was kind of muddy as I recall and has a marshy part in the middle. There are tons of prairie dog holes especially on the north end. There are lots of warnings for rattlesnakes once you exit the trail on the south end. I probably won't be back here anytime soon.

Didn’t actually do left hand as it was closed due to mud. So did sage instead, which was also incredibly muddy.

super easy with nice views!

Single file trail through open pasture some with cow herds which was fun and takes you to the reservoir which is beautiful. Nice run through wide open foothills

This is great loop for running, even better, you can string it together by starting at Wonderland lake and taking the Foothills Trail over to Eagle, then take Eagle out to 55th(the Boulder Reservoir road) head south to Jay rd. and then west through the NoBo Neighborhoods back to Wonderland Lake. I think it's like 12 - 13 ish miles.

Decent walking trail. Portion of trail takes you through cow pasture. Lots of dog, horse and cow poop on trail. EASY walk if you just want to stretch your legs.
