Swimming at Lun Beach is generally safe in calm conditions, though it's a more natural, less supervised beach than urban alternatives. The area lacks regular lifeguard services, so swimmers should exercise caution and assess conditions independently. The beach is near the famous abandoned Lun-class ekranoplan, but the craft itself is a beached museum piece and not a hazard. Water depth increases gradually, and the seabed is sandy. Always be mindful of weather conditions and avoid swimming during strong winds or rough seas on the Caspian.

Lun Beach is best visited during shoulder seasons—late May to mid-June or September—when you can enjoy pleasant weather with minimal crowds. Weekday mornings offer the most solitude even during summer months. Unlike Derbent's more popular beaches, Lun Beach remains relatively uncrowded throughout the year due to its slightly remote location. Early morning or late afternoon visits provide the best lighting for photographing the iconic ekranoplan. The beach is accessible year-round, though swimming is only comfortable from June through September when water temperatures are warmest.
