Summit Hall Farm Park Pool is a sprawling waterpark complex next to Gaithersburg High School. The huge swimming area includes multiple pools, a 60-foot water slide and four large picnic areas. Lawn chairs are lined up like dominos around this hilly, shaded park area which provides plenty of space to soak up the sun. The pool is attached to the complex's adjoining skate park and mini golf course. Combination swim and golf passes are available.
