I rode this trail the day before the eclipse. I did a round trip from Jackson to Jenny Lake. The trail is awesome, with great views of the Tetons all the way. Other than a couple minor climbs, its a cake ride. I parked at the Jackson Visitor's Center and despite the signs saying 2 hour parking, I asked and was able to park my car in their lot for the entire trip. The Jenny Lake store has a water bottle re-fill station with THE best water! Can't wait to go back next summer..

Rode a total of 21 miles on this trail in June, 2016 with my grandson and about the same again in June, 2017 with my wife. With the nearby mountains and meadows there is ample photo opportunity. The trail is asphalt with only minor elevation variance. If I'm ever in this area again I will be sure and ride this trail again.

My dad and I rode this trail starting at Ashton. He rides a comfort bike and I'm on a hybrid. I loved the views, but I pretty much hated the trail surface. I'm not a fan of mountain biking and that was part of my problem! It was widely variable with lots of softs spots, rocks, ruts, and other things I wasn't a fan of riding over! Also, there is no shade!

Went with my wife and 14yr son from Tetonia to Ashton. Took about 5 hours. Started about 130p and finished before 7p. It was fun and will do it again. We choose the Tetonia to Ashton direction because it's had a net downhill grade. Glad we did because this is the first bike ride for my wife and 30 miles is a long way to go for a beginner. She was a real trooper and finished in first place.

Overall it was a great ride. Beautiful scenery, easy ride and no one else on the trail.

I rode this trail from Ashton towards Tetonia on a HOT July day. Although I started before 9am the temperature was near triple digits by noon. Despite the heat, which necessitated turning around about halfway, this was a lovely ride. You can't beat the views as you bike up to Tetonia. The rivers and streams, the various crops in full bloom, the trestles and not one other person on the trail! I'm not antisocial but I do like having a trail to myself! ¿¿ A couple things to take into consideration if riding this trail: there's no water so pack plenty; use the potties when you see them as they ate few and far between; take a mountain bike as parts of the trail are rough; start in Ashton if you're planning an out and back as then on your way back when you're tired it's a downhill coast.

we rode from Tetonia to Ashton and back on a hot afternoon. The trail is wonderful and the bridges spectacular. The views of the Tetons on the way back are indeed well worth it. We did not find too many soft spots (except in the detour) and rode on our cross bikes, which worked fine for us.

This ride is definitely worth doing from Ashton to Tetonia so the Tetons are always in your view. Trestle bridges are cool too.

Over the length of the 30 miles, there's variation in the trail bed with some places being smoother/rougher than others. Our family of 5 (youngest was 8 years old) rode it in 6 hours with long lunch break on a hot day (85 degrees+). We didn't have any flat tires. We felt the "detour" section was the most difficult simply because of the hilly roads you had to travel.

I had heard rumors that the AT trail was OK for cross bikes, so I tried my Trek Crossrip Elite with 700x32 tires out this morning. The verdict: Take your mountain bike, preferably with decent suspension. Most betweener-type-bike riders would find the AT a disappointingly slow, bone-jarring slog. And at the 20-mile mark (from Ashton), you cross a tricky rocky causeway with a long drop off on both sides.
The trail was fine, well-marked and in generally good condition, and there's great scenery (only the iconic Teton Mountains in the distance!). Surfaces are wildly variable, ranging from packed dirt to loose rock to gravel to gritty sand to bumpy tufts or widely spread grass. Passing over the bridges is a blast, but make sure you slow for the cattle-gate-type funnel at one end of each. You pass through mostly open country with only occasional stands of trees. Grades are gentle and you won't often find yourself needing to shift. One exception is the diversion south of Drummond, where you (if you start from Ashton) are first sent on a county two-track road between farm fields. There are a few steep pitches, and if the farmers are irrigating, the track can be pretty muddy. Careful there.
Most riders will find a 30-mile, one-way trek (I suggest starting from Tetonia most days) plenty of work. (I took the AT trail from Ashton to Tetonia and then Highway 32 back to Ashton. Just couldn't run my ill-suited bike back again.) There are nice opportunities for out-and-back trips covering part of the trail from both trail heads, but Ashton gets you to the longer bridges sooner, and the Tetons are in front of you.

My wife and I just finished riding from the Moose Crossing Visitors Center up to Jenny Lake. About 15.5 miles round trip. This is a great trail for all ages. There is only one hill climb in this section, just after the park entrance but it can be done without much trouble. The rest of the trip to Jenny Lake is up hill but a very gentle climb. We saw some great scenery along the way including beautiful landscapes, some wild life and lots of June desert flowers. When you get to Jenny Lake there is a store, restrooms and lots of places to rest for the trip down the hill. Don't forget to check out the lake... it is beautiful. The return trip back to the Visitors Center goes quick and easy. The trail is in great shape... we only saw a couple of places where the roots of trees had rippled the asphalt. I would recommend this bike path to anyone who likes getting out of town to ride and enjoy the sites.
