This is a jumping off point for a lot of trails. There's a couple of easy options through the valley and some others that climb up the ridgelines and lead to some great views.

From the trail, there is a nice view of the valley just before the land kicks up into the mountains. You can parts of the Bitterroot River and into Missoula.

While technically this trail is rideable in both directions local etiquette suggests that uphill traffic is better taking the parallel Sawmill Gulch Road so that downhill traffic can feel the flow. Whichever direction you ride keep an eye out for oncoming traffic.

This is the spot for a rest and refuel. Since it's the high spot on the trail it means you've put in the work and deserve a little break before reaping the reward of the descent.
