Pro Tips

  1. 1.Book ferry tickets online in advance during peak summer weekends,they can sell out, especially for popular Georges Island departures.
  2. 2.Start with Spectacle Island if you have younger kids; it has the best beaches, visitor center with bathrooms, and easiest terrain for little legs.
  3. 3.Pack a picnic lunch, sunscreen, and plenty of water,food options are extremely limited on the islands with only small snack bars on select islands.
  4. 4.Wear sturdy shoes for exploring the rocky shores and fort areas; flip-flops aren't ideal for most island activities.
  5. 5.Check the ferry schedule carefully and plan to catch an earlier return boat than you think,missing the last ferry means a long wait or expensive water taxi!

Best Time to Visit

Visit on weekday mornings in June or September for smaller crowds and pleasant weather. Summer weekends can be very busy, and the ferry service typically runs late May through mid-October only. Early departures give you the most island exploration time.

What to Know

Ferry tickets cost approximately $20-30 for adults and $15-20 for children depending on the island, with children under 3 free. Ferries depart from Long Wharf near the New England Aquarium. Bring cash for the small snack bars, and note that facilities are basic with limited restrooms.

Seasonal Notes

Ferry service operates seasonally from late May through mid-October only, with most frequent service in July and August. Spring and fall offer fewer bugs and cooler temperatures ideal for hiking. Some islands have limited or no service outside peak summer months, so check schedules carefully before planning your visit.
