Not a bad trail. Moderate climbs but mostly flat compared to the rest of the area. One caveat is that this is listed as a 18.6mi trail but the loop itself is closer to 9 so they must be talking about running the course twice.

Good trail to see the landscape of the area. Not much elevation gain but a fun trail none the less. Took about an hour and a half to go all the way around. Good trail for beginner or intermediate riders.

This trail is nice and relaxing and very convenient. A little busy, but would still do it again!

Great trail for beginners. I've been riding for a month and this was great. Good uphill. It can tend to get very crowded. But what good trail won't.
