This 40-acre Maryland island has no roads, no bridge, and a story from 1634

The Quiet Island Where Maryland Started

About half a mile off Colton’s Point in St. Mary’s County, a 40-acre island sits alone in the Potomac River. There’s no road in and no bridge out.

You reach it only by private boat or a seasonal water taxi, and that’s exactly what keeps it so quiet.

Step off the dock and you find open grass, wide sky, and river views in every direction, plus a story that starts back in 1634, before Maryland was even a colony.

The Ark and the Dove Land in 1634

English settlers reached St. Clement’s Island in March 1634 aboard the Ark and the Dove, under the Baltimore proprietorship. Maryland now marks March 25 as Maryland Day because of it.

Jesuit priest Father Andrew White said the first Catholic Mass in the English-speaking colonies there, while the group searched nearby for land to settle.

The island later turned private as Blackistone Island, held by one family for more than 160 years, until the Navy took over in 1919. It became a state park in 1962.

A 40-Foot Cross Marks the Landing Spot

As your boat nears the island, a stone cross rises 40 feet above the shoreline, and it’s the first thing most people notice.

Built in 1934 to mark 300 years since the landing, the cross honors St. Clement’s Island as an early home of religious freedom in America. It’s the island’s best known landmark, visible long before you reach the dock.

Once you’re on land, the trail leads right up to its base, where most people slow down and take a photo before moving on.

A Grass Trail Links Every Landmark Here

A marked trail runs the length of the island, and it’s grass the whole way, not pavement, so comfortable shoes make the walk easier.

The path stays flat from one end to the other, more of a stroll than a hike, and you can cover it without much effort. Interpretive signs line the route, filling in the island’s story from the 1634 landing to today.

The trail ties everything together, running from the boat dock past the cross and the lighthouse before ending at the picnic area.

The Lighthouse Rebuilt From Its Own Ashes

Near the south end of the island stands a two-story lighthouse with a tower rising from its roof. It’s a full replica of the original Blackistone Lighthouse, first built in 1851.

That original burned down in 1956 after vandals set it on fire. A local volunteer group brought it back using the 1851 blueprints, finishing the rebuild in 2008.

The replica sits on higher ground than the original did, and from its base you can look out over the ruins of the first lighthouse.

Watching the Potomac From Every Direction

The island sits in a wide stretch of the Potomac River, so water surrounds you no matter which direction you look. From the shoreline, you can see clear across to the Virginia side.

Because the island stays low and open, nothing blocks the view, and the light turns especially good in the early morning and again at dusk.

Benches and picnic tables sit along the scenic east side, giving you a place to sit and take it in. Plenty of people stay until sunset, timing it to catch the last boat back.

An Island That Lost 90 Percent of Itself

When the colonists first arrived, the island stretched out to as much as 400 acres. Centuries of river current wore that down to roughly a tenth of its original size.

To keep what’s left from disappearing too, volunteers and local groups placed large boulders around the shoreline. Those stones slow the erosion and hold the remaining land in place.

Walk the island today and you’re standing on the last piece of a place that used to be far bigger.

Spotting Waterbirds Along the Island’s Edge

Sitting out in the middle of the Potomac makes the island a solid spot for birdwatching. Waterbirds, gulls, and shorebirds show up regularly along the open shoreline.

With so few people around, wildlife tends to stick closer and stay longer than it would somewhere busier. Bring binoculars if you can.

They help across the open water and along the marshy edges where birds tend to gather. Early morning is usually when the birds are most active.

Fishing Along the Island’s Quiet Shoreline

Fishing draws plenty of people to the island’s edges.

You cast right from the shoreline into the Potomac, and the calm, uncrowded setting makes for an easy afternoon. Pair it with a picnic and a slow walk around the island, and you’ve got a full day without much effort.

Just remember there are no shops here, so bring your gear, bait, and anything else you need before you get on the boat.

Pack a Picnic and Skip the Crowds

A covered picnic pavilion sits on the island, open on a first-come, first-served basis. Tables and benches line the scenic riverside along the east shore, with the water right there as your view.

The setup stays rustic. There’s a composting toilet and nothing else in the way of services.

There are no trash cans either, so whatever you carry in, you carry back out. Bringing your own water, food, and shade is just part of how a day here works.

The Fall Festival That Fills the Shoreline

Each fall, southern Maryland holds the Blessing of the Fleet to honor its watermen. The tradition has run for more than 50 years, celebrating both the watermen and Maryland’s founding.

It grew up around this stretch of the Potomac and the story of the island’s first landing. The day mixes a boat-blessing ceremony with music, food, and a fireworks show.

The location can change from year to year, so it’s worth checking ahead of time to find out where that year’s event will be held.

Why This Little Island Sticks With You

Not many places let you walk the exact spot where a colony got its start.

Here, the mix of open water, a cross reaching 40 feet into the sky, and a rebuilt lighthouse comes together in a way that feels timeless. Getting there only by boat turns the trip itself into a small adventure.

In the end, it’s the quiet and the wide river views that keep pulling people back. If you like history, water, and days that don’t rush you, this island delivers all three.

Visiting St. Clement’s Island State Park in Maryland

You can visit St. Clement’s Island State Park off Colton’s Point in St. Mary’s County, Maryland, where the island covers about 40 acres.

You reach it only by private boat or a seasonal water taxi that used to run from the nearby St. Clement’s Island Museum, torn down for construction, so check the official website for access. Park hours run sunrise to sunset.

Amenities stay simple: a trail, a picnic pavilion, and a composting toilet, with no water, food, or trash service, so bring what you need and carry it out.
