Very good trail for beginners who want to learn to ride some rocks and roots but nothing "scary" by any means. Some loose sand or light gravel in some spots. Only a couple of spots they had to walk but an advanced rider won't have an issue.
Minimal elevation gain so great with dogs. There is a creek on the right side of the rock (see map pic. Blue dot is where the creek is for dogs).
Great family ride but still need good bikes. Don't bring your 30 year old cruiser. Tons of trails all over. All levels. It got the teen boy interested in riding with me!
For my two years as a graduate student at U. of Wyoming, Happy Jack has been my go-to for emergency nature visits. At just 15 mins or so from Laramie, this trail is so easily accessible when I need to run my dogs or find some quiet. Surprisingly, even being so nearby I have more often than not found the place entirely to myself, though I've seen lots of cross-country ski tracks, trail runners, and the like year round. The only disadvantages to this place are the fact that snow comes heavy and often makes the trailhead inaccessible by vehicle, and also that the nearby highway can snap your dream state at certain points in the trail. High summer months also bring intolerable waves of biting flies and mosquitoes. I have seen moose in these parts more than any other land animal, as they especially like the mountain pools. I have had some really joyful experiences with this very convenient trail, especially with my dog who loves it even more than me. I'll be sad not to have this in my backyard anymore.
It was an easy hike, mellow and nice scenery. There were lots of families of all ages around. So for those who are newbie hikers or have little ones it's a great little hike. Lots of places to picnic at so pack a lunch, a camera and some binoculars because there are moose around the area as well. We saw three a couple summers ago.
