Practical notes
Atami's largest day-use onsen. The signature 25 m infinity standing bath lines up sky, sea and hot spring. Source water is 55°C calcium-sodium chloride. The Loyly Camp (80°C, feels like 100°C) is free but reservation-only, so book at the 3rd floor as soon as you arrive. The view sauna runs cool at 45°C, so head to the Loyly Camp if you want real heat. Showing a Mitsui Shopping Park point card or the app gets you an admission discount. Children from age 3 are charged.
