Kelly Flats has long been the premier hard-core trail in northern Colorado. The trail climbs steeply out of the Cache La Poudre River Valley and winds for a considerable distance across a high ridge with beautiful views of the Mummy Range on a clear day. Noted obstacles include The Chutes and Heart Attack Hill. A wet spring often delays May 15 opening of the trail, so call ahead to verify. ATVs and UTVs may find this trail too difficult. Located in Roosevelt National Forest. For current conditions call Canyon Lakes Ranger District (970) 295-6700. First part of trail is extremely steep and rocky. Middle is easy as it passes through a residential area. Last part has some large mud holes. Body damage is a frequent occurrence on The Chutes. Not for stock SUVs.

Took two ATVs at the end of June. Heart Attack Hill lived up to its name. Check out our YouTube video going through the chutes. We took the trail start to finish. Amazing variety of butterflies and a good mix of terrain. Saw a lot of mountain lion scat on the trail at the top.

Loved this trail, definitely requires locking 4x4 in some spots. Made it the whole way in a stock 1991 Land Rover Defender, took the bypass and was still a challenge. If you pick your lines, it can be done. Everyone we met on the trail was awesome, as it can get quite narrow and with blind corners. Keep you eyes peeled!

This was a great ride on my ATV. Went in October saw a mountain lion crossing the trail at the top of Heart Attack Hill was pretty cool.
