Barking Frog hangs off of Hairy Toad Loop
, and while it continues Toad's theme of rocky natural trail surface, it unwinds itself a bit, opening up the corners and coming out into a series of meadows, then diving back into dark cedar groves, crossing a wet woodland on a series of narrow boardwalks (one curved), before returning to Hairy Toad.
Even flatter than Hairy Toad, it's a great introduction to this type of riding if you aren't ready for the Toad yet. Just ride out on the Isle Royale ski trail which crossed Frog right near its start and finish. Rides nice both ways.
