I live along this trail (that's our vineyard), so it gets a 5 for convenience. You can make it easy by staying on lower half of loops, or go high for climbs. Markings could be better. Its a fairly recent acquisition, so new growth still in some areas. Just past the boardwalk is golf course and riding stables. We often extend hike through there to Devil's Backbone trail and Fall Creek Loop trail. For that trip, plan for 3-4 hours. Done alone, this trails takes an hour for all 3 loops at 3 mph.
