You’re standing at the bottom of Arch Street in Greenwich. The sun is beating down. You can smell the salt air, but you can’t actually see the sand yet. That's because Greenwich CT Island Beach—or Little Captain Island, if you want to be technical—is about two miles offshore. It is arguably the coolest thing about living in or visiting Fairfield County, yet it’s surprisingly easy to mess up the logistics. Honestly, if you miss the ferry by two minutes, your beach day is basically toast for the next hour.
Most people think of Greenwich and envision high-end boutiques on the Avenue or massive hedge fund offices. They don't think of a sub-20-acre island with 1920s changing rooms and a view of the Manhattan skyline on a clear day.
Getting there is a bit of a ritual. It’s not just a beach; it’s a logistical maneuver.
The Ferry Situation is Everything
You can't drive to Island Beach. Don't even try to find a bridge. The only way on is via the town-operated ferry or your own boat. The ferry departs from the landing at Roger Sherman Baldwin Park.
The boats themselves, like the Island Beach and the Indian Harbor, are vintage-feeling workhorses. They’ve been shuttling people across the Sound for decades. The ride takes about 20 to 25 minutes. It’s the best part of the trip for some. You get that breeze hitting your face, you pass the fancy yachts in the harbor, and the humidity suddenly feels manageable.
But here is the catch: You need a park pass.
Greenwich is notoriously protective of its coastline. If you aren't a resident with a seasonal pass, you have to buy a daily park pass and a ferry ticket online in advance. Gone are the days of just handing a guy five bucks at the dock. The town moved to a digital system a few years back, and it catches people off guard constantly. You’ll see families standing by the ticket booth staring at their phones, trying to navigate the municipal website while the boat pulls away. Don't be those people.
Check the schedule. It changes. High tide, low tide, and mechanical issues can throw a wrench in things. Usually, it runs every hour on the hour from the dock, and every hour on the half-hour from the island.
What Actually Happens Once You Land
The boat docks at a long pier on the north side of the island. You walk off and immediately feel the temperature drop.
Island Beach is unique because it’s a "destination" park. It has a massive stone beach house that looks like it belongs in a black-and-white movie from the thirties. It’s got that weathered, classic New England aesthetic. There are changing rooms, restrooms, and even a snack bar.
Is the snack bar amazing? It’s fine. It’s typical beach fare—hot dogs, burgers, ice cream. But honestly, most locals pack a massive cooler.
The island is tiny. You can walk the entire perimeter in about fifteen minutes if you’re moving fast, but why would you? The south side of the island faces the open Long Island Sound. That’s where the "real" beach is. The sand isn't Caribbean white—it's Connecticut sand, which means it’s a little coarse and there are shells. Bring flip-flops.
Why This Island Beats the Mainland Beaches
Greenwich has Tod’s Point (Old Greenwich), which is beautiful and sprawling. But Island Beach feels exclusive in a way that isn't about money. It’s about effort.
Because you have to take a boat, the crowd is self-selecting. There are no cars. No traffic noise. Just the sound of the water and the occasional ferry horn. There’s a certain peace there that you just can't find at a public park you can drive to.
- The Picnic Areas: There are grills scattered around. If you get there early enough, you can snag a table under the trees. Grilling a steak on an island two miles from the mainland while looking at the Greenwich shoreline? That’s the dream.
- The Birding: If you’re into that sort of thing, the island is a stopover for all sorts of migratory birds. The back side of the island is more rugged and less groomed, perfect for spotting ospreys.
- The View: On a crisp day, you can see the skyscrapers of New York City. It feels surreal. You’re in this quiet, rocky oasis, yet the biggest city in the world is shimmering on the horizon.
The "Secret" Side of Greenwich CT Island Beach
Most people stay on the main crescent of sand near the pier. That's a mistake. If you head to the western or southern edges, you find these little rocky outcroppings.
At low tide, tide pools form. Kids love this, obviously, but even as an adult, it’s cool to see the crabs and small fish trapped in the rocks. It feels like a different world.
The water quality is generally good, but like any beach in the Sound, it’s worth checking the Greenwich Department of Health website before you go. After a heavy rain, they sometimes close the beaches for a day or two. There’s nothing worse than paying for the ferry and getting to the island only to find out you can't go in the water.
Survival Tips for the Trip
Pack light, but pack right. Remember, you have to carry everything you bring onto a boat, off a boat, and across the island.
- The Cooler: Use one with wheels. The walk from the ferry to the far side of the beach isn't miles, but it feels like it when you’re lugging 40 pounds of ice and drinks.
- The Sun: There is very little shade on the actual sand. The interior of the island has trees, but if you want to be by the water, bring a sturdy umbrella. The wind can pick up out there.
- The Trash: It’s a carry-in, carry-out situation for the most part. Keep the island clean. People are very protective of this place.
- The Last Ferry: Do not miss it. Seriously. They will count heads, but you don't want to be the reason the crew has to stay late, and you definitely don't want to be stuck there after dark.
Understanding the "Town Resident" Dynamic
Greenwich is a town that takes its private/public distinctions seriously. For years, the beaches were restricted to residents only. A massive Supreme Court case (Leydon v. Greenwich) changed that in 2001, opening the gates to non-residents.
However, the town still makes it a bit of a hurdle for outsiders. This isn't necessarily out of malice; it’s about capacity. The island is small. If 5,000 people showed up, it would be a disaster. The current system of day passes and ferry fees keeps the numbers manageable.
If you're a non-resident, expect to pay a premium. Between the day pass and the ferry ticket, you might be looking at $20-$30 per person. Is it worth it? Absolutely. It’s cheaper than a round of golf or a fancy lunch on Greenwich Avenue, and the experience is far more memorable.
The Seasonal Nature of the Island
Island Beach isn't a year-round destination. The ferry service typically starts in mid-June and runs through mid-September (Labor Day is usually the cutoff, though sometimes they extend it for a weekend if the weather is perfect).
In the "off-season," the island belongs to the birds and the occasional kayaker brave enough to paddle out there. If you have your own boat, you can anchor off the coast, but the ferry dock is strictly for the town boats.
Actionable Steps for Your Visit

First, create an account on the Greenwich Parks and Rec website. You can't just "guest checkout" easily. Do this the night before. You'll need to purchase a Single Entry Park Pass for every person in your group who isn't a resident.
Second, buy your Ferry Tickets. These are separate from the park entry pass. You need both. Check the ferry schedule on the Town of Greenwich website—it usually updates seasonally.
Third, arrive at Roger Sherman Baldwin Park at least 20 minutes before your departure. Parking at the dock can be a nightmare on weekends. There is a designated lot, but it fills up fast. You might end up parking in the multi-story garage further up the street and walking down.
Fourth, check the weather and the water status. Call the Greenwich beach seaflow line or check the town’s health department page. If there's a "No Swimming" advisory, the ferry might still run, but the experience won't be the same.
Fifth, bring cash for the snack bar. While many places take cards now, tech on an island can be spotty. Having a twenty-dollar bill for an emergency ice cream cone is just smart planning.
Island Beach is a gem. It’s a slice of old-school Connecticut summer that hasn't changed much in a century. If you handle the paperwork and the timing, it’s the best day trip in the tri-state area.
