“The original Red Fleet Trail that started it all.
— Tildon Jones
Watch for the closure signs: this trail is within the blast zone for the Simplot phosphate mine. Blasting usually occurs during business hours, but can happen at any time. Take the signs seriously--at best, you'll lose some hearing, at worst you'll be hit by flying rocks.
This is the original Red Fleet trail. Start from the dirt parking area 0.6 miles from US 191.
The trail immediately starts on a fun, flowing singletrack downhill. Cross the wash on the culvert, head along the fence and up the bottom. At the junction, follow signs to the left to begin the first climb.
Once at the top, you'll swing right into another short, downhill section. Check your speed because this is tight, narrow singletrack. At the bottom of the hill, head left to continue up a small valley.
After a couple of wash crossings, you'll see another sign directing you left to the second climb. At the top of this hill, continue left through a juniper section which takes you to the BLM-Simplot boundary. The trail continues along the fence line in a roller coaster segment of short ups and downs.
As you leave the boundary line, you enter the "Jazz Gets Down" downhill. This is a really fun segment of singletrack descent where you can get some speed and flow going. This section is one-way only!
At the bottom of the hill, make a sharp right turn to continue on JCM back to the parking area. You'll climb out of the wash to a doubletrack, where the trail crosses and continues to a water trough. From there, head left for a long, low angle descent. Watch out for the black water pipe crossing the trail--many people have lost their rear tire there.
At the next water trough, bear right to a short downhill where you head back into the valley and eventually start back on the trail the way you came. After following the fence line and Hwy. 191, you'll cross a wash culvert/cattle guard and start heading up hill. At the bermed turn heading left, watch for the blast warning sign and a faint trail heading down to the paved road.
Please climb back to the TH on this road to avoid fast downhill traffic coming down the trail.
