The route

  1. Start at the Houghton’s Pond kiosk, 840 Hillside Street, Milton.
  2. Follow the yellow triangles east along Hillside Street.
  3. Stay on the yellow triangles through rugged woods and rolling hills in the Great Blue Hill section.
  4. The triangles only point one way. Walk the loop counterclockwise to stay on the marked route.

Before you go

  • If you get lost or hurt, call 911. Give the dispatcher the four-digit number on the nearest intersection post. Those numbers match the DCR map and help responders find you. For non-emergency park concerns, DCR’s 24-hour dispatch is (508) 820-1428.
  • Before you go, share your phone’s location with a friend, and tell someone your route and when you plan to be back.
  • Carry the DCR trail map. Many intersections have a white post with a four-digit number that matches the map.
  • Wear sturdy shoes, bring water, and dress for wind on the summits.
  • The reservation is open dawn to dusk. Dogs must be leashed. Carry out everything you bring in.
  • Timber rattlesnakes and copperheads live in the Blue Hills. They are shy. Stay on the trail and give them space.
