This 625-acre property became a state park in 1996. It is named for the sand dunes near the center and western end of the south-facing, natural sand beach. This beach is amongst the longest beaches on Lake Champlain.

The beach and dunes together make up what is known as a barrier island, geologically similar to coastal formations more common along ocean shorelines. At Alburgh Dunes, the sand has come from a layer of glacial till- the soil that was left atop the low bluffs southeast of the beach when the last glacier melted. The bluffs have eroded over thousands of years, and the soil carried off by lake currents. Sand from that soil settles out in the pocket between the rocky Point of Tongue to the east and Coon Point to the west, forming the beach. Prevailing southerly winds, in the late summer and fall when lake levels are the lowest, blow the sand back from shore, forming dunes. It's a barrier between the lakeshore and the wetland behind, and an island because the beach and dunes, however slowly, continue to migrate into and over the wetland. Deposits of exposed peat are visible on the low end of the beach or in the shallow water just offshore. This peat was formed in the wetland as the beach and dunes have moved back the peat has been overlaid by sand. Erosion from the waves continues to uncover it.

Alburgh's dunes were altered before the area became a state park. Portions of the dunes were bulldozed for sand with which to replenish the beach. Protective vegetation was damaged or destroyed when trees were cut for firewood, and beach visitors climbing through and over the dunes wore pathways through the stabilizing grasses. These changes hastened beach and dune erosion. Today, protective fencing is installed around the dunes. Its hoped the dunes will eventually repair themselves. Please help us protect this unique sand dune area by staying outside of the fence. The fence is both to minimize human disturbance, and to protect rare plants growing inside. Two species of rare plants, Champlain beach grass and the low-growing beach-pea, are remnants from the post-glacial era in which Lake Champlain was an inland estuary of the Atlantic Ocean. Isostatic rebound, a slow-rising of the earth's crust once freed from the great weight of the overlying glacier, has raised Lake Champlain to its current 30 meter 100 foot elevation above sea level. Thousands of years of rain and snow melt have flushed out the sea water.

The wetland behind the beach includes the largest black spruce bog in Grand Isle County. Black spruce swamps and bogs are more typical of colder, northern climates than of the Champlain Valley, which is Vermont's warmest area. Core samples from the bog reveal peat to depths of more than 8 meters 26 feet. From these samples comes a record of climate and vegetation dating back to the ice age, and further evidence of isostatic rebound.

Alburgh's wetlands are important to wildlife, providing habitat for breeding, feeding, nesting, and over wintering. The park's wetlands and adjacent white cedar forest uplands are the primary components of the largest and most important deer wintering area in Grand Isle County. Wild turkey, too, are abundant in and around the area. Alburgh Dunes certainly lends itself to wildlife viewing
1. Alburgh Dunes State Park offers a 2000-foot natural sand beach for swimming.
2. Lifeguards are not typically present at the park's swim areas.
3. Swimming is allowed from sunrise to sunset during open season, usually May through October.
4. The water in Lake Champlain remains relatively warm due to shallow depth near the shorelines of this state park.
5. There are no designated swimming pools; all swims take place in lake waters with marked boundaries for safety purposes.

Enjoy fishing on the shores of Lake Champlain, with species like northern pike and smallmouth bass. Other options include walleye, yellow perch, and lake trout. The park also offers ice fishing during winter months for hardy anglers seeking a challenge.

Birdwatchers can spot species like the Common Tern, Piping Plover and Least Bittern. The park is home to rare birds such as Grasshopper Sparrows and Upland Sandpipers. Other birding highlights include Ospreys, Northern Harriers, Marsh Wrens and Sedge Wrens.
