A community pool in the Bannockburn neighborhood of Bethesda, Maryland, Merrimack has been keeping members cool for 50 years.

In 2005, Merrimack was completely rebuilt. Today, we have a 7-lane competition pool and a large diving well with dual 1-meter boards. We also offer a wonderful kiddie pool area with a beach entry, bubblers and a "lemon drop" fountain sprayer. A transition pool area is perfect for kids just learning to swim. We have picnic areas, ping-pong, free wi-fi, BBQ grills, plenty of parking and a large bathhouse that was renovated just a few years ago.

Merrimack offers competitive swim and dive teams, with meets against other area pools from mid June through the beginning of August every year. Swimming and diving lessons are always available.
