The pool, the hot springs and lunch
The Secret Lagoon operator lists the bathing water at 38–40°C. Around the pool, the walking path passes boiling springs and Litli Geysir; stay on that path to watch them. The springs that supply the pool are a separate part of the visit from the water you bathe in.
Plan a meal separately if you want hot food: the on-site bistro lists snacks and drinks and explicitly says it does not serve warm meals. Towels and swimsuits can be rented, but bringing your own avoids those extras. These facilities were checked September 10, 2026; use the operator’s opening-hours and booking pages for your date.
