There is a paved foot & bike path that runs straight through the park to Arroyo Road, though I am not sure if it actually has an exit onto the road. It continues further into Veterans Park. Of the gravel trails some are closed to bikes for nature preservation reasons. Others allow for a (mostly) easy gravel ride.
