Ruby Mountain is located 1.7 river miles downstream of Fisherman's Bridge. A good access area with a campground and large boat ramp. It is found by turning on CR 301 like your going to Fisherman's Bridge, but continue a hundred yards or so north on 301 to the intersection with CR 300 (there are signs for Ruby), and take 300 east for 2-3 miles to the campground/access.
