Rash Canyon is out of the Fall Creek area just before Swan Valley, Idaho. There are numerous trail heads out of this area and some trails are better than others. This trail which starts out at Rash Canyon and loops around into South Fork Fall Creek, isn’t one of our most favorite rides because you are basically stuck on a two-track dirt road the entire way and also stuck in a canyon so you don’t get much of that high view overlook. We did still manage to get some good photos with the Olympus Tough.
It is a good trail however for getting your horses in shape and conditioned. The whole area of Fall Creek is very populated mostly by motorized vehicles. We definitely don’t recommend coming here on a weekend, as you will run into more motorized vehicles than you wish. There is also a lot of opportunity to camp along the way. There are several spots just off the dirt road where you can pull over and camp. There are also a few spots off by some of the trailheads if you want more of a secluded camping experience. We also ran into a few camping spots along the trail so if you want to pack in and camp that is also a possibility.
Finding the Rash Canyon Trailhead
From Idaho Falls, ID: Follow US 26 towards Swan Valley for about 30 miles. Just before you cross the bridge over the Snake River, you will see a road to the right titled NF-058 this is a paved road for about a mile and will take you past a boat ramp. This part of the road is relatively wide, but be careful as you will most likely encounter a few big rigs on this road. In a little over a mile you will come to a fork in the road, continue right onto Fall Creek road. This turns into a narrow dirt road with some turn outs along the way in case you run into a larger vehicle. Sometimes cattle semis are seen on this road. Follow this dirt road for about 5-6 miles until you come to a sign on your left that says Rash Canyon.
As you pull onto this short road be careful it is steep, rutty, and rocky. We went over the cattle guard and parked in the grassy area on the right. If you would prefer, you can find a place to park off the road on the other side, but you will have to ride across the road and then open a gate.
Rash Canyon Trail Description
Follow the two-track dirt trail. In about 3 miles into the trail you will come to a junction with a possibility of continuing straight or going to the right or to the left. If you continue straight you will be on the road that will loop you into South Fork Fall Creek.
We decided to take a little back country way because that is the way that Amy programmed it on the Suunto Ambit 2 Watch. So we headed to the right up trail 262 even though there is a sign in a tree once you turn onto this trail pointing the way to South Fork Fall Creek. In less than a mile you will come to another junction and turn on the road to the left. Shortly you will see an unmarked trail to your right that doesn’t look very well-kept, you need to take this trail. We ended up missing this and taking a trail just down the road that had a marker on it that says no motorized vehicles. This trail is a dead-end and we advise you not to take it. If you take the correct trail, you will immediately find a little cow trail to the right. Take this and you will intersect with the South Fork Trail. Take a right once the trail intersects. We saw deer on this trail.
Once you are on the South Fork trail, you will hear and see the creek to your right. There were some mallard ducks resting in this creek and also some big fish swimming past.
As you continue on this trail, you will see a sign that points to Lightning Ridge. It was pretty fitting at this time as we started to hear thunder at this moment. Luckily we didn’t get rained on. Keep on the road, and soon you will come to a junction where the South Fork trail splits. Turn left and you will be on your final leg back to the truck. We crossed the creek several times here and there were many opportunities for the horses to get drinks.
When you reach the end of the South Fork trail you will come to a giant turn around parking area. You will be coming out on trail marker 30. The truck is not parked here so follow your way out on the road and turn left on the gravel road you drove in from. Follow the gravel road for about 1.5 miles until you see that sign again for Rash Canyon. The down fall here is, this road can be busy with traffic so be careful .
Once you turn down the road to Rash Canyon you will come to that cattle guard you drove over. There is very tight barbed wire gate around the fence corner to the right, but we decided to just go grab the truck and drive it over the cattle guard and unsaddled there. It was a lot easier than messing with that gate.
**Reminder: If you have the Suunto Ambit watch you can import all of the maps we provide of our journeys onto the watch and have your own personal guide telling you where to head on the trail 🙂
