Nice trail for getting some miles in, not too technical - a good training loop.

Great hike, easy walk with a few ups and downs. Narrow trail is shared with mountain bikers, no issues. Didn't see many people and the ambience was quiet.

Great hike. Will come back to run it next week. Not hard. Length is the only thing that makes it Moderate.
