      Trail really isn’t that fun. No obstacles for the most part and creek crossings constantly. Hard to ride through them so best to dismount. Nice workout but probably won’t return here. The Bonelli network is obviously right by and much more worth it. The shade is nice though

      An absolute blast of fun and challenge on a mountain bike. The trail crosses thru the river a dozen times. Definately much easier hiking this trail than it is mountain biking. However, going from the top to the bottom is much easier, but riding back up to the top, definately very hard. There's no public restrooms, but there is several spots along the trail with picknic benches.

      Overall, for a mountain bike, it's definately something you would want to do on a hot day as you will very very very likely be wet and muddy. You'll want to make sure you lube your chain with wet lube. If you're only riding this trail, you probably wont need sunglasses as most of the trail is covered by trees. Make sure to bring spare shoes, socks and towel.
