2026 Marine Park Niihama Full-Day Course

A full-day course that showcases Marine Park Niihama (opening from July 11–August 31, 2026) as the highlight while enjoying Niihama's main attractions from morning to evening. In the morning, visit the Akagane Museum near Niihama Station to explore the city's history and art, then pay respects at Ichinomiya Shrine, known for the Niihama Taiko Drum Festival, to pray for safe travels. After lunch at Aeon Mall Niihama, head to the main event: Marine Park Niihama. The beach is fully equipped with changing rooms, hot coin-operated showers, and toilets, and swimming is free. Operating hours are 8:30 a.m. to 7:00 p.m., so you can enjoy plenty of time in the water until evening. An adjacent campground offers the perfect location for families wanting to spend a full day enjoying both day-trip swimming and outdoor activities. Grab your swimsuit and towel and head out to enjoy summer in Niihama.
