The Nantucket ferry from Hyannis is one of the busiest passenger routes on the East Coast every summer, and two operators run it: the Steamship Authority (the only service that carries cars) and Hy-Line Cruises (passenger-only and faster). For the vast majority of visitors, the right move is to leave your car in Hyannis, walk on, and navigate Nantucket by bike or shuttle — the island is small enough that a car creates more problems than it solves. Here is everything you need to plan the trip correctly.
The Two Operators: Steamship Authority vs. Hy-Line Cruises
Both services depart from Hyannis and arrive at Nantucket's Steamboat Wharf. They are not the same product.
Steamship Authority (SSA) is the public authority that has operated this route for generations. Its traditional ferry carries vehicles and passengers and takes approximately 2 hours and 15 minutes each way. This is the only service that can bring your car to the island. Round-trip foot-passenger fares on the traditional ferry are $43 per adult, $21.50 one way, for the 2026 season (steamshipauthority.com). The vessel has a cafeteria, a snack bar, an outdoor upper deck, and enclosed seating — comfortable for families and well-suited for the longer crossing. SSA departs from South Street Dock in Hyannis.

Hy-Line Cruises operates a high-speed catamaran that crosses in approximately 1 hour — passenger-only, no cars. Round-trip fares are $97 per adult, $52 one way (hylinecruises.com), roughly double the SSA slow ferry, but you gain well over an hour of island time each way. A First Class upgrade provides reserved outdoor deck seating and additional amenities. Hy-Line departs from Ocean Street Dock, roughly a 10-minute walk from the SSA terminal.

Which should you choose? For a day trip where time is the constraint, Hy-Line's speed justifies the premium. For families on a budget, or anyone who prefers a relaxed crossing with more deck space and a cafeteria, the SSA traditional ferry is perfectly comfortable. The two operators run different departure times, so check both — it is entirely practical to take Hy-Line outbound and SSA on the return, or vice versa, to maximize your schedule.
Do You Actually Need to Bring Your Car?
For nearly every visitor, the answer is no.
Nantucket is 14 miles long and 3.5 miles wide. The historic downtown — cobblestone Main Street, the wharves, the shops, the Nantucket Whaling Museum — is walkable from Steamboat Wharf. The island's NRTA Wave shuttle system covers the main corridors, including routes to Surfside Beach, Madaket, and Sconset. Bike rental shops operate steps from the ferry landing — expect to pay $35–$50 per day for a quality rental (confirm current rates) — and dedicated, paved bike paths connect the town to every major beach.
SSA vehicle reservations to Nantucket are expensive, hard to obtain, and genuinely unnecessary for most trips. The SSA opens vehicle reservations for peak summer months well in advance — check the current release schedule at steamshipauthority.com — and prime weekend sailings fill immediately. Standby vehicle spots exist but carry no guarantee. Vehicle transport costs add substantially to an already premium fare.
The only situations where a car makes clear sense: you are relocating to the island for the season, you are transporting equipment or large quantities of gear, or a member of your party has mobility requirements that make bike and shuttle travel impractical.
Parking at the Hyannis Ferry Terminal
The Steamship Authority operates a parking facility directly at South Street Dock. This is the most convenient option — park, grab your bags, and walk to the boarding area. Reserve parking when you book your ferry tickets. On peak summer weekends, this lot fills completely, and arriving without a reservation risks missing your sailing entirely. SSA parking fees vary by season.
Hy-Line passengers have a separate facility near Ocean Street Dock. The same rule applies: book it with your ferry tickets.
If both terminal lots are sold out, several public and private parking options exist within walking distance of the Hyannis waterfront. The area is compact, and a 5–10 minute walk with a carry-on bag is manageable for most travelers.
One timing note that matters: if you are driving down from off-Cape on a July or August weekend morning, the Bourne and Sagamore bridges — the only two road connections to the Cape — generate significant backups starting before 9am on Saturdays. Leave early. Missing your Nantucket ferry because of bridge traffic is a real and avoidable problem.
Schedules, Timing & How to Book
Both operators run multiple sailings daily in peak summer. First departures from Hyannis typically begin in the early morning and last return sailings from Nantucket run into the evening — confirm current sailing times with each operator. Schedules thin out in shoulder season (late May, early June, September) and contract significantly in fall and winter.
Booking guidance by operator:
- SSA foot-passenger tickets: available at steamshipauthority.com; same-day walk-up is possible but July and August weekend sailings can sell out, so book as soon as your dates are confirmed
- Hy-Line tickets: available at hylinecruises.com; Friday outbound and Sunday return sailings move fastest — book early
- SSA parking can be bundled with ferry tickets at checkout
- Arrive at least 30 minutes before departure as a foot passenger; 45 minutes if you are taking a vehicle
Sunday return sailings deserve specific attention. The same logic that clogs the Sagamore and Bourne bridges every Sunday afternoon plays out at Nantucket's docks. Everyone tries to leave the island at once. Book an early Sunday return if you can, or — if your schedule allows — consider departing Monday morning. The difference in experience is substantial.

Day Trip vs. Overnight: What You Can Realistically Do
A day trip from Hyannis to Nantucket is genuinely worthwhile — especially if you take the early Hy-Line departure and plan deliberately.
A realistic summer day-trip sequence: catch the 8:00am or 9:00am Hy-Line sailing, arrive at Steamboat Wharf before 10am, rent a bike at one of the shops along the wharf, ride the 2-mile dedicated path to Surfside Beach for a swim on the Atlantic, pedal back through town for lunch on Main Street, walk the cobblestones and browse the shops in the afternoon, and catch a 5:00–6:00pm return. You will have 7–8 solid hours on-island if you move through it intentionally.
What a day trip does not accommodate: the full Sconset loop (a beautiful 13-mile round-trip bike ride to the east end of the island with views that reward the effort), a proper afternoon in the Nantucket Whaling Museum, or a sit-down dinner at any of the island's destination restaurants.
An overnight stay — even a single night — resets the entire experience. Once the day-trippers depart, Nantucket becomes a different place: quieter docks, uncrowded restaurants, the kind of evening light that makes the gray-shingled houses look like they belong to another century. Nantucket lodging in summer books out months in advance; plan accordingly.
