Frog Falls Water Park at Picatinny Arsenal in Rockaway Township is open for the 2026 summer season, giving families across Morris County a place to cool off through Labor Day. The membership facility runs each year from Memorial Day into early September.
Operated by Picatinny Arsenal Family and MWR, Frog Falls holds more than 520,000 gallons of water. The park features two high-velocity slides, a lazy river, a zero-depth entry leisure pool, six 25-yard lap lanes, and a child activity pool for the youngest swimmers. A snack bar, designated picnic area, and shaded lounge seating round out the grounds.
Membership is open to Picatinny Arsenal families and to residents of partnered communities, including Rockaway Township, Rockaway Borough, and nearby Morris County towns. Registration is handled online at FrogFalls.com, which routes members through the Army MWR Webtrac portal. A $10 registration fee applies per membership, and every member over the age of 18 must complete and pass a background check before entry.
Day guests are welcome when accompanied by a member and cost $15 per person. Swimmers must be at least 48 inches tall to ride the slides, and all pool passes must be picked up in person at the Picatinny Visitor Center on Parker Road.
Families with questions can reach MWR Customer Service at 973-724-3697 or review full membership details on the Frog Falls Water Park page. Rockaway Township also lists the park among its local facilities.
