Right on the edges of town outside of the Hidden Valley subdivision, you'll find this fun little set of trails that's pretty good for mountain bikes. It is mostly a dirt bike playground but there's plenty that has mountain bike crossover as well as a mountain bike specific singletrack. There's an old road that heads up through the gully and tons of off-shoot dirt bike trails up the sides. There is no shortage of gap jumps, it's just a matter of choosing and having enough speed. Again, most of these are intended for dirt bikes. The old road is pretty washed out and pretty chunky so it makes for a little more technical uphill climb. Climb all the way to the top and you'll get a great view of Hidden Valley with the farms to your back. You could bomb back down the road from there or take the single track further down off the East end of the road.

Hidden Valley Loop: This is just a couple of old double track farm roads that converge at the top to make a nice little loop hike. It's the perfect trail if you just need somewhere close to go trail running or biking for your morning workout or even if you just want to go for a peaceful walk. The "Loop" is two separate roads that come together on the south end. If you're riding a bike, the higher East road makes for a good climb and the lower West road has a decent flow as a downhill trail. The West road follows along just below the back side of the houses on Millhollow Road. The vegetation along that hill side can be very pretty. When you get to the top of the trail, you won't be at the top of anything but the road but there's still a pretty good view of Hidden Valley and some of the Eastern side of Rexburg and out through the valley.

Hidden Valley Singletrack is a tight trail with tight corners and sagebrush closing it in even more. It's pretty rocky and has a couple small drops/rock-rolls. Janky describes it well. There are a few gap jumps that you'll need to find some speed for. There are a couple of off-shoots that will drop you right back down to the road to hit some of the bigger jumps below. There's an off-shoot at the end of the trail that you've got to take if you don't want to end up in the field but it's pretty clear where that is when you get to it.

Dr. Jekyll is the road you climb up and as a climb, is pretty technical in places with some pretty tricky line choices through rocky sections. The ride down faces similar challenges through the rocky sections, except with gravity on your side. Visibility is much better on the road than in the sagebrush and there's considerably more flow and even some small rollers to jump.
