Echo Lake is a glacial lake situated within Franconia Notch State Park in Conway, New Hampshire, USA.

Visual Characteristics

The lake has a surface area of approximately 10 acres. Its water color varies from deep blue to green depending on depth and light conditions. The shoreline is primarily composed of sand and gravel, with surrounding vegetation consisting of mixed deciduous and coniferous trees. The lake is bordered by the granite formations of Franconia Notch.

Location & Access Logistics

Echo Lake is located directly off Interstate 93, Exit 34A. It is approximately 1 mile north of the Cannon Mountain Aerial Tramway base station. Parking is available in a designated lot adjacent to the lake, with capacity for approximately 50 vehicles. No public transport directly serves the lake; access is via private vehicle or taxi.

Historical & Ecological Origin

Echo Lake is a remnant of the last glacial period, formed by the retreat of glaciers approximately 10,000 years ago. It is a typical example of a kettle lake, formed by a buried ice block melting and leaving a depression that filled with water. The surrounding Franconia Notch is a geological feature shaped by glacial erosion and tectonic activity.

Key Highlights & Activities

Swimming is permitted in designated areas during the summer season. A sandy beach provides access to the water. Kayaking and paddleboarding are permitted. Hiking trails circumnavigate portions of the lake, offering views of the surrounding mountains. Fishing is allowed with a valid New Hampshire fishing license.

Infrastructure & Amenities

Restrooms are available near the main parking area. Picnic tables and charcoal grills are provided. Shade is available from surrounding trees. Cell phone signal (4G) is generally available, though it can be intermittent in certain areas of the park. No food vendors are located directly at the lake; visitors should bring their own provisions.

Best Time to Visit

For swimming and beach activities, the months of July and August are optimal due to warmer water temperatures. For photography, early morning or late afternoon light provides softer illumination on the lake and mountains. The lake is accessible year-round, but winter conditions may limit access to certain areas.

Facts & Legends

The name "Echo Lake" derives from the acoustic phenomenon where sounds can be reflected off the steep granite walls of Franconia Notch, creating distinct echoes. A local legend suggests that the lake's depth is unknown, though geological surveys indicate a maximum depth of approximately 40 feet.
