Just outside the border, on French soil, the Monte-Carlo Beach Club adjoins the Monte-Carlo Beach Hôtel, avenue Princesse-Grace (tel. 04-93-28-66-66; The beach club has thrived for years; it's an integral part of Monaco's social life. Princess Grace used to come here in flowery swimsuits, greeting her friends and subjects with humor and style. The sand is replenished at regular intervals. You'll find two large pools (one for children), cabanas, a restaurant, a cafe, and a bar. As the temperature drops in late August, the beach closes for the winter. The admission charge of 65€ Monday to Friday and 80€ on weekends grants you access to the changing rooms, toilets, restaurants, and bar, and use of a mattress for sunbathing. A fee of 160€ will get you a day's use of a private cabana. Most socializing occurs around the pool's edges. As usual, topless is de rigueur but bottomless isn't.

Monaco, the quintessential kingdom by the sea, offers swimming and sunbathing at the Plage du Larvotto, off avenue Princesse-Grace. This strip of beach is free, and the surface is frequently replenished with sand hauled in by barge. Part of it is open; other sections are private and owned by beachside restaurants.
