Along the Golden Circle, this is a great stop to heat up. It's also a great alternative to Blue Lagoon, has a beautiful view of the lake (be sure to hop in the lake for a cold plunge), and provides a good look into local pool culture. This spa is also one of the most kid-friendly.

There are two heated pools, a hot tub, steam room, and sauna.

Prices are reasonable and kids under 12 are FREE! Towels and swimsuits are available for a small rental fee.

You may also book a short demonstration and tasting of rye bread that is baked in the ground - heated geothermally overnight.
