Echo Lake sits in a bowl carved by glaciers, its western shore lined with granite shelves that slope gently into water the color of aged pewter. The ledges absorb sunlight all morning, turning the stone into natural loungers by noon. You arrive through a canopy of white pine, the path barely wide enough for two, emerging onto flat rock platforms scattered with lichen in burnt orange and sage green.

The swimming here rewards patience. Wade in from the ledges and the bottom stays visible—sand, then pebbles, then the occasional submerged boulder draped in green filaments. On windless mornings the surface mirrors Beech Mountain's ridgeline, doubling the forest until your first stroke fractures the reflection. By afternoon, breeze from the Atlantic gap stirs up small rollers that slap the ledges in lazy rhythm.
Families claim the wider platforms early, spreading quilts over the granite and lowering coolers into shaded crevices. The water temperature hovers in the high sixties through August, ten degrees kinder than the nearby ocean beaches. You'll hear laughter bounce off the rock face across the lake, watch teenagers leap from higher perches, feel the stone's retained warmth on your shoulders as you drip-dry in the slanted light of late afternoon.
