Directions: Steamship Authority or Hy-Line ferry service available from Hyannis and Woods Hole, MA (travel time 1-2hrs). Most regularly scheduled flights available from Boston, Hyannis and NY City (LGA). You will need a cab to downtown from the airport.
Ferry docks at Steamboat Wharf or Straight Wharf where taxis and rental bikes are readily available. Proceed to Information House on Federal Street and Pick up the free map published by "Butterworth" Map Company, this is the most accurate and detailed of the free maps available. Roadside trails to Milestone Rd. or Polpis Rd. trailheads are paved. Milestone Rd. entrances to trails are the closest to Nantucket town, and can be taken all the way to "Sconset", quite possible the most beautiful town in the US.
Mile markers on Milestone Rd. are well-marked by white stones on on the north side of the road. There are trail entrances just past the 1 mile stone, at about 1.75 mi. and approximately 2.5, which is closest to a lookout over the bogs. Polpis Rd. entrances include just east of Shawkemo Rd. or at the end of Altar Rock Rd.
Trail Information: Rolling, sandy trails with sublime views of Nantucket conservation area, cranberry bogs, moors and America's loveliest Island. There are few trail markings, although some point to Alter Rock lookout (elev 90'), which is an excellent vantage point to plan your run. Surrounding land is delicate and aggressively protected by Islanders and visitors alike, be courteous and respectful, although the occasional Range Rover full of teenagers will seem to turn this warning on its head. This area is almost entirely uncovered by trees and more like beach running, but it is a unique experience at the right time of day (sunrise, sunset) and year (Oct. cranberry season).
Miscellaneous Information: *No Water/Few Markings (bring a buddy)
*Nantucket has many other great roads biking trails for short or long runs.
*Great location for a weekend running/biking getaway.
*Cars can be ferried to Island, and rented on-Island; costs for both are unusually high and not
necessary given multiple transportation options.
