I rode it out and back from the North end. Super fun. No hikers. Maybe my favorite trail in Prescott. The perfect balance of climbing and descending.

Elevation gain is off. More like ~400' of climbing from Badger/Ranch intersection to 69. Super fun trail. Fast, flowy, well-built, and scenic. One of the best downhills in Prescott.

This trail is a blast to ride if you go downhill instead of climbing

Great sustained climb or descent and a good out and back. Think it's 5 miles at 1000ft so it's a pedaler's descent. Also, a solid but fair climb. Great for aspiring intermediates that want to do a longer climb/descent. There are some fun technical bits and great views of the Bradshaw Mountains toward Spruce and Mt Union as well as views of Thumb Butte and Granite Mountain.

I rode from senetor past boy scout a few miles which got really fun. Little bit of chunk, switchbacks, berms, flowy spots. Cool views right from the gecko. Solid climb back up but well worth it!

Sweet, fast, flowy descent...sunset/night riding especially yields an unparalled Prescott city skyline views! Take a gander from the metal bench...totally worth the climb!

I took a shuttle up to the p-lot at aspen creek trail head. The trail starts about 100m down the road (copper basin rd) with a fire road leading up to the trail. It’s about a mile uphill before you can start enjoying the views and speed of trail 9415. Some techy stuff but nothing to cream your pants about. The sand and loose gravel sure made some sections extra spicy.

Trail 347 (Lower)
This is actually still trail 347 Lower so if you park at the Katahn Dr trailhead look for the sign with 347.

Super fun trail if you park off senator Highway and take it East Bound its the Best way. I would only recommend shuttling this trail because to come back up it its long. *DO NOT GO UP 9854 ACCESS ROAD TO GET BACK* I would recommend having 2 vehicles one to park at the bottom off of walker rd and then have the other at the trail head off senator Highway. Very fun long downhill Only go eastbound

As of May/June the first half sucks because someone walked their horses on it when it must’ve been wet, but after a few miles it gets good. Loved the grooves on the way back! You really get pumping and flowing! Beautiful views too!

Good trail but heavy logging bolldozer tracks scatter everywhere across n down trail. Use the trail to north until this on has a few more months to rehab. It will return to b a great woodsy singletrack soon

Lots of open grassland but trail has many many water bars, err, jumps so loads of fun. Best with a dropper post.
Would not be interesting going up.

Super fun trail, I wish I would have started up top rather than jumping in at the boy scouts intersection as that trail was a joke. I’d try this one again from the top it has quite the mix and flows nicely if you keep some speed ????????

This was a fun trail to ride with young kids (6&Cool , enough small hills and switchbacks to keep it fun, but easy enough for everyone. Not much shade for hot/sunny days, great in winter.

On a website that ranked Prescott trails, it said this was the #1 trail in the area.... have to say I've ridden some much nicer and more fun trails in the area. This is just a couple mile grind of a climb and a semi tech decent. Nothing special. But as always opinions are like buttholes, everyone has one and they stink.
