This loop incorporates some of the best trails into one large loop, for more advanced riders. It includes some twisty trail on the prairie and technical trail in the trees. Riding these trails in this direction makes a nice, long, fun ride.
If you are feeling like you need more mileage, add the trails to the north of Arrowhead
(across the Glendo Park Road), like Toadstool
and Narrows Bluff Trail
Starting from any campsite in Two Moon (the best camping in Glendo for mtb. folks), take Two Moon Loop
to Buffalo Run
, crossing the road. Buffalo Run
is a nice, casual ride through the prairie and then along the rim looking down on the power plant.
A few rideable switchbacks on 91 Gigawatt
will take you down to the Power Plant. Cross onto the road, head across the bridge, and jump on the first singletrack you see to your left (but don't go left onto Raptor), staying straight. Switchback after the fence now starts up the most difficult climb of the ride on Rattlesnake Rim
. Good luck cleaning the tough rock sections (if you do it all, you are a rad rider!)
At the top of the climb, duck off to the right to add Porcupine
as a loop if you feel that 14+ miles is too short. Continue on Rattlesnake Rim
until you hit the junction for Feather Rim
(but don't take the right turn for Turkey Spur
!). If you start descending switchbacks down Rattlesnake Rim
, you missed your turn.
is probably the best segment of this ride; you are always "on" and this trail feels a lot longer than it actually is. At the end of Feather Rim
, stay straight and follow Thunder
. This will put you to the top of Slide Hill Loop
, which is best ridden down (sweet teeter-totter!).
At the bottom of Slide Hill Loop
, cross the road to gain the other trail system and to access Slide Hill Loop East
. Slide Hill Loop East
can be full of hikers, so be respectful. I take Slide Hill Loop
back over the road again because that downhill is super fun.
Jump on Barrel Roll
to descend back down to the lower part of the dam. This area can be confusing, as there are multiple intersections. Each intersection has a map and a number. Reference the number on the post to find out where you are on the map. This loop adds the bottom of Thunder
to intersect with Wetland Trail
(which is a dirt road) at the bottom. Cross the bridge back down river, and then connect with Rocky River
on the other side. This is a fun, somewhat technical trail.
You are probably getting tired now, just one more significant climb up Root Canal
before you are back towards your campsite! Root Canal
has a significant climb in it. Once up top, take Reflector Loop
to the right, then Broken Bow
to connect to Two Moon Loop
on the east side of the campground. Follow Two Moon Loop
back to your campsite!
All these trails have been built since 2012 specifically for mountain biking. Many trails are consistently technical and require you to move your bike. There is less focus on open-it-up flow trails. Expect these to be harder miles than what may be typical.
