Just outside the border, on French soil, the Monte-Carlo Beach Club adjoins the Monte-Carlo Beach Hôtel, av. Princesse-Grace (www.monte-carlo-beach.com; tel. 04-93-28-66-66), a five-star sister establishment of the ultra-elegant Hôtel de Paris. Princess Grace used to frolic here, and today it’s an integral part of Monaco social life. It now has an Olympic-size swimming pool, a La Prairie spa, cabanas, a poolside fine dining restaurant, and a low-key Mediterranean restaurant. Beach activities include inner tubes, jet skis, and parachute rides. As the temperature drops in late October, the beach closes for the winter. The admission charge of 60€ to 150€, depending on the season, grants you access to changing rooms, toilets, restaurants, and bar, along with use of a mattress for sunbathing.

More low-key swimming and sunbathing is at Plage du Larvotto, off avenue Princesse-Grace. Part of this popular man-made strip of sand is public. The other part contains private beach clubs with bars, snacks, and showers, plus a kids’ club. A jogging track runs behind the beach.
