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.

Need to Know

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.

Feather Rim 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 to Arrowhead. 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!

History & Background

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.

Love the teeter on Slide Hill. Lots of hike-a-bike on Feather Rim for those without massive lungs/legs. Bring lots of water when it's hot.
