Castello Di Vicarello

Cinigiano, Italy

Perched on a hilltop surrounded by gently rolling hills, the Castello di Vicarello is a splendid escape — made more splendid by not one but two swimming pools with views of the Tuscan countryside.

Grand Hotel Tremezzo

Lake Como

This one’s got three very fine swimming pools, but it earns its place on this list with just one: a floating pool deck surrounded on all sides by the waters of Lake Como.

Hotel Les Roches Rouges

Saint-Raphaël, France

Les Roches Rouges, in Saint-Raphaël, is a quieter, less developed side of the Côte d’Azur, and the hotel pool, strangely, sums it up: it’s a saltwater pool, cut directly into the rocky hillside, looking out over the Mediterranean.

Hotel Molitor

Paris

Hôtel Molitor doesn’t just have a pool, it is a pool — the Piscine Molitor pool complex was a Parisian landmark for decades, and now it’s back in business, this time with a stylish luxury hotel wrapped around its edges.

ION Adventure Hotel

Selfoss, Iceland

It’s not the hotel’s main attraction, not by a long shot, but the geothermally heated pool at ION — actually more like a ten-meter hot tub — is among the most unique features of this unforgettable Icelandic escape.

Mandarin Oriental

Bodrum

The main pool is extraordinary enough to merit a mention — Mandarin Oriental have taken to coastal resorts like a fish to water — but the property’s many, many private pools help the hotel’s case as well.

Marbella Club Hotel

Marbella, Spain

Marbella Club’s pool isn’t the biggest, or the grandest, or the most imposing on this list — but what it is is perfectly formed and perfectly picturesque.

Mystique Hotel

Santorini

This one’s all about the view. Oia, on Santorini, is one of the most picturesque places on earth, with a perfect angle on the island’s volcanic caldera — a view that’s only improved by a dip in a cliffside infinity pool.

Sant Pere Del Bosc Hotel & Spa

Lloret De Mar, Spain

Set within a lush lawn, with the hotel’s towering façade as a backdrop on one side and the rolling green hills on the other, this pool is a sight to behold, nearly as impressive as the Mediterranean coast below.

Tainaron Blue Retreat

Peloponnese

This restored watchtower, on the site of an ancient temple to Poseidon, is only improved by the addition of an infinity pool — an innovation the ancient Greeks would surely have embraced wholeheartedly.
