Alburgh Dunes State Park
151 Coon Point Rd
Alburgh, VT
One of the longest natural sand beaches in Vermont, backed by a fragile dune system and a bog boardwalk, on the quiet northern tip of the Champlain Islands.
Alburgh Dunes protects something Vermont has very little of: a true sand beach with a working dune system behind it. The beach stretches for most of a mile along the southern shore of the Alburgh peninsula, its sand built up over thousands of years by wind and the long fetch of Lake Champlain. Behind the sand lies a low ridge of dunes held in place by beach grass, and behind that a rare wetland of bog and sandplain forest.
It is an easy place to underestimate. Many visitors come simply to swim in the warm, shallow water and never realize they are standing on one of the most unusual natural communities in the state, home to plants that grow almost nowhere else in Vermont.
What Guests Love
- A long, gently curving sand beach that feels more coastal than inland
- Warm, shallow water that makes for easy swimming on a hot day
- The boardwalk trail through a black spruce and tamarack bog
- How uncrowded it stays compared with beaches closer to Burlington
Worth Knowing
- The dunes are fragile and planted with beach grass to hold the sand, so stay on the marked paths and off the dune faces
- Facilities are simple; bring water, shade, and anything else you need for the day
- The shallow water warms early but can grow weedy by late summer
- There is a day-use fee in season, and the park keeps limited hours outside the summer months

Learn about Alburgh Dunes State Park
A beach where a beach should not be
Sand beaches are scarce in Vermont because most of the Lake Champlain shoreline is rock, clay, or cobble. Alburgh Dunes exists because of a lucky combination of geography: a shallow bay, a long stretch of open water to the south for waves to build across, and a steady supply of sand sorted out of the glacial deposits that blanket the region.
Over the centuries, wind pushed dry sand up off the beach into a ridge of dunes at the back of the shore. Beach grass took hold and its roots knit the sand together, and that grip is the only thing holding the dunes in place. When people walk across the dune faces the grass dies and the sand blows loose, which is why the park asks visitors to keep to the boardwalks and paths.
The bog behind the sand
A short boardwalk trail leads back from the beach into a very different world: a cool, acidic bog of black spruce and tamarack, the tamarack being one of the few conifers in the world that turns gold and drops its needles every autumn. The ground is a spongy mat of sphagnum moss.
This pocket of northern bog and sandplain supports uncommon plants, including insect-eating pitcher plants and sundews that trap bugs to get the nutrients the poor soil cannot provide. It is a fragile, slow-growing community, and the boardwalk exists to let people see it without trampling it.
A crossroads of the lake
The Abenaki have lived in the Champlain Islands for thousands of years, fishing the lake and moving through this water country by canoe, and the Abenaki people remain here in Vermont today. The lake that Alburgh Dunes faces was a travel corridor long before it carried European names.
Alburgh itself became an odd corner of the map. The peninsula connects by land only to Canada, so for generations residents reached the rest of Vermont by ferry or over ice in winter, until the lake bridges tied the islands together. That out-of-the-way quality is part of why the beach still feels like a secret.
Season by season
Summer is the reason most people come, when the shallow water warms quickly and the long beach invites a slow afternoon. Weekends draw families, but the sheer length of the shore keeps it from feeling crowded.
Late summer can bring aquatic weeds into the warm shallows, more nuisance than problem. Autumn is quietly spectacular when the tamaracks in the bog turn gold, and the off-season leaves the beach almost entirely to the wind and the birds.
