Plan your visit
Bringing kids
OK with supervision
Lifeguards are on duty only part of the season (weekends from Memorial Day, then daily after the last day of school through Labor Day), so the beach is unsupervised outside those windows. No source describes the swim area's depth, roped-off shallow zone, or bottom conditions, so parents should treat it with normal lake-swim caution, especially when lifeguards aren't posted.
Hours
Daily 10am-6pm (per the Borough's official recreation page); lifeguards only cover weekends from Memorial Day and then daily after the last day of school through Labor Day.
On the water
Restrictions: The Borough's own rules state 'no fishing or launching of kayaks from the Municipal Beach during operating hours' (10am-6pm). The only kayaking tied to the beach is an organized 'guided kayaking' outing the borough runs on the first Saturday of each month through October, not general public launch-your-own-boat access.
No mention of canoes, paddleboards, or motorized craft at this beach specifically; Lake Hopatcong overall is a large multi-use lake with boating elsewhere, but that's not documented as available from this beach.
Backstory
The beach is formally named the Arthur Ondish Memorial Beach, though no further background on the namesake was found in the sources reviewed.
