- Take Exit 14 off Mass. Route 3 (MA228, Rockland).
- Take MA228 northbound to Nantasket Beach (almost 10 miles).
- At the beach, the road name changes to "Nantasket Ave."
- Continue on Nantasket as it winds past the beach.
- The road bends to the left and you'll pass the Spinnaker Island Causeway on the left (a private residence).
- At this point, the road name changes to "Main St."
- Continue on Main until you pass the ferry terminal (left) and high school (right).
- You'll see informal parking along the gravel beach ringing the peninsula. Parking is free, but in the off-season you may compete with commuters using the MBTA ferry. There are usually porta-johns on-site during the summer.
