Heated pool on the Athens Riviera: swim without the shivers

South of the capital, the Athens Riviera follows the Saronic Gulf from Glyfada to Vouliagmeni, then on to Lagonissi. At Vouliagmeni, the water of the lake stays at around 22 °C all year, a naturally mild bath. Elsewhere, the sea cools noticeably outside summer: hotel spas, a thalasso pool and villas with a heated pool extend the season. I've selected 6 places, all rated at least 8/10; the top-rated is Indoor pool villa Lagonisi 4-BDRM near the beach (10/10).

Fancy hot water? The hot tubs

These places don't have a confirmed heated pool, but they do have a hot tub: the water is hot all year round. A good way to relax in the warm.

The hot tub. Large private outdoor pool (not advertised as heated) and a private jacuzzi in a spacious garden, at a four-bedroom villa (sleeps up to 10).

The pool comes up in 11 guest reviews. The listing doesn't say whether the water is heated.

Guide's tip. For a warm dip outside summer, count on the jacuzzi rather than the pool: ask whether it's heated year-round.
