This trail is a fantastic wide path perfect for both climbing and descending. There are a few steep sections if you want to go uphill, but if you decide to ride back down, your reward is a fluid downhill ride. Climbing is manageable if you're in good shape, but don't be discouraged if you need to walk some parts, it's worth it! This is also a popular spot for hikers, so keep an eye out for others also enjoying the trail.

The perfect spot for a break! No shade here, but there is a bench, an informational panel, and a wooden observation deck. The views over the marshland here and the bay are pretty amazing.
