Site details

Niles Beach sits inside Gloucester Harbor on Eastern Point, giving it some of the most protected water on Cape Ann. The gradually sloping sandy bottom only reaches about 15-25 ft, so it serves mainly as a training venue and a reliable backup when ocean-facing sites are blown out. Summer parking requires a Gloucester resident beach sticker, though walk-on access is open to all.

muckshore

Very shallow (15-25 ft max); boat traffic from Gloucester Harbor and the adjacent yacht club moorings — tow a dive flag and stay alert; cold water; reduced visibility after rain or boat wakes.
