The Button Rock trailhead is a family friendly hiking trail with beautiful views along the North St. Vrain Creek. The trail has a loop option that takes hikers to Button Rock Dam and the Ralph Price Reservoir. This trail is on a dirt road, so hiking remains very simple, strollers can be used, and you’ll find many anglers fishing along the way. There is also an additional option along the Sleepy Lion trail which adds a little more distance and difficulty.

Hikers can choose to do the entire loop, turn around at any point.

Trails

 

Button Rock Dam To Ralph Price Reservoir Loop – 4.41 Miles Round Trip – 833 Feet Elevation Gain

This is our recommended family friendly loop hike. Hikers start out along the Longmont Dam road at the Button Rock Trailhead and simply follow the road all the way until Button Rock Dam. The entire route to the dam has gorgeous views of the North St. Vrain, passes by rock climbing areas, and great fishing holes.

1.5 miles in, hikers reach the junction of the loop (a bathroom is located here). To the left is towards the dam, and to the right heads up towards Ralph Price Reservoir. If doing the loop, we recommend you head towards the dam first, as it is better to hike up the steeper section at the dam than down it. Hikers will reach the dam, and bear right up the right hand side of the dam. The trail switchbacks to gain elevation to reach the top of the dam.

Hikers bear right to complete the loop and head back towards the trailhead.

 

Sleepy Lion Trail Trail & Ralph Price Reservoir Loop – 5.32 Miles – 1,207 Feet Elevation Gain

If your hiking group is feeling up for a slightly more difficult route, we recommend bearing left off the road to the dam to hike along the Sleepy Lion Trail. This trail has more elevation gain, but gives hikers a stunning view of Button Rock Dam and the Ralph Price Reservoir down below. The sleepy lion trail is .86 miles from the trailhead.

Hikers can also choose to take this trail but then simply descend down to Button Rock dam and exit out via the road. This will cut out some mileage if interested.

 

Other Trail Options

Hikers can choose to walk as far as they please and turn around on the main road. Also, the dirt road is well maintained all the way to Button Rock Dam, or to Ralph Price Reservoir if they bear right before reaching Button Rock Dam.

 

Ralph Price Reservoir

There are also trails going part way around the lake (North Shore Trail) that hikers can continue on. There is a lot of gorgeous wildlife like deer, eagles, osprey and many other birds around. There is no camping or swimming in this area.
