Travel north on Route 6 north to Provincetown. Turn right on Race Point Road at your first stoplight. Look for signs marking the Beech Forest area and Province Lands Visitor Center. There is plenty of free parking here -- and the trail begins at the top of the hill near the observatory.

Ask for a free bicycle trails brochure here. Make sure you walk up to the observation deck and enjoy the panorama view of the dunes and ocean before heading out on the bike trails. Bring your bathing suits and enjoy a refreshing swim along the way -- either at Race Point beach -- or Herring Cove beach.

If you're on a fitness quest, you'll get plenty of exercise going to Herring Cove beach. If you just want to have some seaside fun, then head for Race Point beach and double back to the Visitors center. For a bit more exercise, return by way of doing the loop through Beech Forest.
