I dont know if there is a policy one way or another, but I think most of the trails are too narrow, particularly if you needed to pass hikers or bicyclists. You will want to scout it first.
Hiking and mountain bicycling only on the trails. Reference: http://metamoraparks.org/webpages/bpp.php
No motorized ATV trails are near.
No motorized vehicles allowed on the trails.
