Very nice trail - some elevation change and one easy water crossing. Lovely view along the top. I really enjoy loop trails and I would repeat this one often.

Went for a morning run on this trail. It’s a good single-track trail. Steep in a few areas, and really rocky in others, but for the most part a great getaway. Very pretty.The trail continues into another and could keep going if a longer hike or jog is desired.Posted, no bikes or motor vehicle allowed.I am from Mid South Dakota and hadn’t been out to Rapid Before, it was easy to find and a great place to go out.

Nice views, good trail. Generally well maintained. Not a lot of parking.

Nice hike in the trees on the flume trail for most of it. I love loop trails and this being so close to Rapid its great. Mountain bike would also do well on this one.

Great six mile round trip to Air Force Vista.

Nice, well marked trail with great views, pine trees.

Super pretty out here, trail was a littttle narrow but Im definitely gonna hike it again

Very good trail, loop starts about 2 miles in but you can keep hiking on the flume trail for a while.

Pretty trail! Good for hikers of all ages and ability.

Easy hike for the family.

This loop hike takes about an hour and 45 minutes. It is part of the Old Flume Trail. Easily accessible and beautiful scenery.

Amazing mountain bike trails!!!

Super cool trail

Nice flat hike, unique ponderosa/oak mix. Aspens and a lookout 2.5 miles in

Love it.

We took the flume trail, #50 from the parking lot. Very nice trail especially when we got up higher. I only saw the flume name, not sure why it wasnt the coon hollow trail that we were on. The map at the trailhead was kind of hard to make out, not very detailed. We followed the trail for about two miles, crossed a dirty road started up the other side of road, again on #50, not too far later, we came across another sign with an easier to read map and info about who made the trail from Ellsworth AFB. We turned around at this point because it was not going to be the loop we expected.What I liked about the trail was it wasnt really one that went up and down and up and down, pretty much when we got near the top of the mountain, the trail was fairly wide and kept at the same altitude.When we headed back, when we got back to the road we took another trail which looked to be for bikers which ended up putting us above the #50 trail about 3.5 miles into the hike, using the phone which was tracking our progress, we went down the hill to join the #50 trail and headed back to the coon hollow trailhead. About 5 miles total in about 2 hrs.

Get place to hike
