What Makes Jordan Pond So Special?

Jordan Pond is a glacial tarn, formed over 10,000 years ago by the movement of glaciers. It is approximately 150 feet (46 meters) deep, making it one of the deepest lakes in Acadia National Park. The water is incredibly transparent — often more than 40 feet of visibility — making it one of the clearest lakes in all of Maine.

The pond supports a delicate balance of aquatic life, including native fish species and aquatic plants, all of which are sensitive to pollution and temperature changes that human activity could cause.

Why Swimming is Prohibited?

Swimming is prohibited in Jordan Pond primarily to protect its water quality. The pond serves as the water supply for the nearby town of Seal Harbor. As a source of drinking water, the pond is subject to stringent environmental protections to prevent contamination. Allowing swimming would introduce the risk of pollutants such as sunscreen, body oils, sediment stirred up by swimmers and bacteria, which could harm the water quality and disrupt the ecosystem. Because of this, the National Park Service enforces strict rules that keep the pond protected from human contamination. Boats with engines are not allowed, swimming is prohibited, and even wading along the shoreline is discouraged to preserve both water quality and shoreline vegetation.

Another reason swimming is off-limits is the unique geological structure of the pond. The basin is fed by cold mountain runoff, and the water remains extremely chilly year-round. While this natural coldness contributes to the pond’s clarity and health, it also creates an environment that would be unsafe for casual swimmers. Sudden drops in water temperature can lead to shock or hypothermia, especially in early spring or late fall. Keeping people out of the water prevents unnecessary risk and helps ensure visitor safety.

Recreational Activities Allowed at Jordan Pond

While swimming is off-limits, there are plenty of other ways to enjoy Jordan Pond. Visitors can explore the 3.5-mile Jordan Pond Path, a well-maintained trail that encircles the pond and offers stunning views of the water and surrounding mountains. This hike is relatively easy and accessible, making it a popular choice for families and those seeking a leisurely outdoor experience.

Boating is permitted on Jordan Pond, but only non-motorized watercraft such as kayaks and canoes are allowed. This restriction helps maintain the pond’s quiet, serene atmosphere and protects the water quality. Paddleboarding has also become a popular activity on the pond, offering a peaceful way to enjoy its scenic beauty.

Fishing is another permitted activity at Jordan Pond, with opportunities to catch landlocked salmon and brook trout. However, fishing is regulated to ensure the sustainability of the fish populations, and visitors should check local regulations before casting their lines.

So while you cannot swim in Jordan Pond, you can fully immerse yourself in its beauty—just from the trails and shores rather than the water itself.
