Gunnison Beach generally offers safe swimming conditions during summer months when lifeguards are on duty, typically from late May through early September. The beach is part of Gateway National Recreation Area and features relatively calm waters compared to other Jersey Shore locations. However, always check current conditions before entering the water, as rip currents can occur. Lifeguarded areas are clearly marked, and swimming is only recommended in designated zones. Outside of summer season, no lifeguards are present, so swim at your own risk and exercise extra caution.

The best time to visit Gunnison Beach is from late May through September when weather is warmest and facilities are fully operational. July and August offer peak beach weather with temperatures in the 80s, though these months can be crowded, especially on weekends. June and September provide pleasant conditions with fewer visitors. The beach is technically accessible year-round, but amenities like restrooms and parking lots may have limited hours outside peak season. Weekdays are significantly less crowded than weekends during summer.

Gunnison Beach is located within Sandy Hook in Gateway National Recreation Area. Drive to the end of Hartshorne Drive (Route 36 North) and enter through the main park entrance. There's a parking fee for Sandy Hook (currently around $20 per vehicle in season). Continue north past several beach parking lots to Lot G, the furthest lot, which provides access to Gunnison Beach via a short walk. Parking fills quickly on summer weekends, often by mid-morning. Arrive early or consider visiting on weekdays for guaranteed parking.

Gunnison Beach has basic amenities including restrooms and outdoor showers at the parking area. However, there are no food concessions directly at Gunnison. The Sea Gulls' Nest restaurant operates at Beach Area D within Sandy Hook during summer, about a 10-minute drive away. Most visitors bring their own food, drinks, and beach supplies. The nearest towns with restaurants and lodging are Highlands and Atlantic Highlands, approximately 15-20 minutes away. Several hotels and vacation rentals are available in these areas and throughout the greater Sandy Hook region.

Gunnison Beach is one of the few legal clothing-optional beaches on the U.S. East Coast. The northern section of the beach is designated for nude sunbathing, while the southern area near the parking lot is typically clothing-required. Nudity is optional, not mandatory—visitors may remain clothed if preferred. Photography is strictly prohibited to protect privacy. The beach welcomes all respectful visitors; families, singles, and couples frequent the area. Federal park rangers patrol regularly to ensure appropriate conduct. First-time visitors should understand this is a non-sexual, family-friendly naturist environment.
