From what I gathered on my trip there is that there isn't much serious mountain biking there. There are the rail trail type paths. I think around 40 miles worth. As far as single track there isn't much that bikes are allowed
Schoodic woods campground has paths to ride on...no single track. Not difficult but well maintained. It is nice to ride around the point and up and over back to the campground but hardly mountain biking. There is a sunset rails to trails...not too far away.
Probably better on Mt. Desert island about an hour from Winter Haven on Schoodic point. Cadillac mountain would be a good workout...
Ride to the top of the mountain.
