Rode this trail from Ashton to Tetonia to enjoy the view of the Tetons in front of me much of the way. The slight incline wasn't that noticeable, only when the trail turned from the small cinder-type surface to larger rocks. Surrounded by golden fields of wheat made the ride extra beautiful mid-August. Pre-ride, my SAG driver and I decided on a few little towns we saw on the map for checkpoints with each other. Turns out each of those "little towns" was now only the remaining, abandoned grain elevator. Remember when every little town had a grain elevator?

The Ashton-Tetonia is a trail of the Idaho State Park sytem. As a rail-trail, it makes for a nice level cut through the bountiful and hilly Teton Valley. Beauty abounds while riding in the shadows of the majestic Teton Mountains. I rode the lower half of this trail very recently, beginning at the southern trailhead in Tetonia and going about 15 miles or so to just north of Lamont before heading back. This section takes you across an impressive trestle! It starts off a bit rocky but after about 2 miles the unpaved surface improves quite a bit making for a great ride!

Hit this trail a couple of days ago, starting at the Warm River Campground which is the trail's southern most point. Quite a few hikers and bikers were also enjoying the trail in the great August weather. I rode 8 miles upgrade. At mile 3, you will encounter a closed off rail tunnel. At mile 8, you encounter a fairly wide clearing and junction. I took both spurs, first to Mesa Falls and then the Warm River Springs which besides being great stops added some more mileage to my ride. Above this point, Im told the trail becomes quite challenging. The section I rode was fairly good for an unpaved surface.

Only did 8 miles of this starting in Ashton, but it was phenomenal!! You’re right smack dab in the middle of the rolling hills. Went over an amazing bridge!! The gravel is nicely packed. I rode a fat bike, but we also took kids trailers with suspension and that did great! Someone else rode a cross country bike and did great. So amazing!!

If you're in Idaho Falls it's a must ride as a city trail it's tops. Paved about 6 miles the water falls are beautiful. I had no problem following it across the road. In the summer it is a city full of tourist so watch yourself when crossing roads...

Rode from Felt to Lamont and from Ashton to Drummond. Nice trail with great views. The only problem were the cross trail ruts caused by the moles digging into the trail in the winter (and leaving mounds of dirt that are uncovered when the snow melts) and the larger mammals who burrow into the trail surface and leave either big holes or mounds. It seems that since this trail is a state park, the state needs to put a little more maintenance on the trail surface and get rid of these frequent holes. The trail surface is rough in areas. Maybe the state left it like this for authenticity? The trestles are stunning. The state is making more parking areas to spread out the use as the 5 THs were crowded on the nice Saturday we rode.

Rode from wilson to park entrance. trail is paved the entire way and even though it rides alongside the road, it really isn't that bad. watch for moose though...esp the lifesize models.

The entire jackson pathway is interconnected which the RTC map is in error. We parked at the huge transfer shuttle parking lot which is central to the main trail and spurs.

There are lots of views, turns, hills and benches. Great way to get around the "hole", esp when the main highway into the town is jammed with vehicles and the only bridge in town is under repair and 50% of the car lanes are closed...

Location: Idaho Falls, ID
Parking: Ryder Park, south end of trail
Trail Condition: Some sections excellent, some portions older and needs attention. Good number of sections need some brushing work to clear brush, low hanging tree limbs, and weeds from along the trail.
Signage: Very minimal. Take a map along.
Comments: Overall I really enjoyed this trail. Great scenery and variety of art along trail. It passes through a number of parks and green spaces. A number of other trail users were encountered. I rode the complete trail system and logged 16 miles. From south end to northern end the most direct route was 5.7 miles.

Still under development, but several beautiful loops and extensions are available for short bike day trips or walks. Signage much better now.
