Review: This trail system is not in Roxborough State Park. You cannot access it from the state park since they do not allow mtn bikes. The loops must be accessed from the Indian Creek trail (@~7500 feet in elevation). The loops are @!6400 feet in elevaiton. Its fun getting there, fuin around the loops, and a climb back to the car

Review: Very impressive singletrack with epic views of the front range, Red Rocks, and Nelson Open Space. Start at indian creek trail head, take indian creek trail to RingTail Trail, and go clockwise around swallowtail loops. Everything was marked really well. This is a 4.5 star cross country ride. Had to knock off a half point due to sand and overgrown vegetation.

Review: This is a great ride although there are no technical sections to speak of. You should probably allow about 3 hours or so for the entire ride and take lots of water. It’s also probably best to ride early in the day or wait until the early spring or late fall. The first 4 miles or so is all beautiful forested single-track until you leave the Pike National forest boundary. From there it becomes very exposed to the elements for the rest of the descent to the Swallowtail loops and then the climb back up. I think it was a little over 20 miles for me round trip. Starting from Indian Creek TH you will climb about 1.5 miles to the intersection where you will see a sign for the Ringtail Trail. From here you will climb about another .5 miles then descends for another 3 – 4 miles to the bottom of Nelson Ranch Open Space. The descent from the forest boundary is on an old dirt road and you feel like you can get some serious speed up on this super long downhill (maybe 1000+ ft. descent). Here the trail intersects with the Swallowtail Trail which consists of two loops totaling approximately 3.5 miles in length with striking red rocks, sections over and around these huge rocks, sandy sections and a unique geological perspective of the hogback. The Swallowtail trail down here is overgrown in spots from lack of use but not too hard to follow if you look carefully. Just remember to be prepared for the climb back as there is really no other way out once you get to the bottom.

Review: This trail was real nice. It took about 3.5 hours starting at Indian Creek trailhead. Look forward to some long climbs and some real fast downhill.

Review: Great ride
