About Gunpowder Falls’ Hammerman Beach

Gunpowder Falls is a big state park with many areas. The beach is called the “Hammerman Area.” It has 1,500 feet of sandy, swimming beach divided into several sections by wood ‘groins’ built to trap the sand and protect the beach. You can find a section that fits your needs.

A long grassy hill overlooks the sandy beach, providing great views of the Gunpowder River. It also provides stadium-like seating to lay a towel and watch beach activities.

Lifeguards are on duty from Memorial Day through Labor Day weekend, 8am – 8pm. Lifeguard hours are subject to change. Call 410-592-2897 to confirm.

You can swim other times of the year, but it’s at your own risk.

There is an entrance fee to use the beach. Be aware that if you drive out to get something, you have to pay to get back in. No refunds. 

Hammerman is one of Maryland’s most popular state parks. It fills up on hot summer weekends, especially on the holidays, so get there early on those days. You can call the Hammerman Ranger Station at 410-335-3461 to find out if a park or beach lot closure is in effect.

Dogs are not allowed on the beach during the season (Memorial Day through Labor Day). However, you can let them play on the sand and swim on a leash during the off-season.

This is a great beach to go to if you want to try water sports. This area generally has consistent wind coming down the river, and you can rent windsurfing boards and small sailboats. Kayak, canoe, and paddleboards are also available for rent. You can even get a lesson.

Gunpowder Falls State Park Beach


This is unique to Gunpowerfalls State Park. People do open-water swimming throughout the Chesapeake Bay, but protected swimming is rare.

To show how much it’s ‘a thing’, the state blocks off boating once a year in June so that hundreds of people can swim 4.4-miles across the Chesapeake Bay from Sandy Point State Park near Annapolis.

Open water swimming and long-distance swim training are permitted between the hours of 8am – 10am and 6pm – 8pm. Swimmers are required to sign a distance swimming agreement with a lifeguard before entering the water and must only swim between beaches 1 and 5.
