"Located on the shores of the Mediterranean" is the hotel's own description — its private marina and jetty make that literal for a water taxi.
La Réserve de Beaulieu sits directly on the Mediterranean, with a small private marina and jetty used for swimming and watersports rather than a sand beach. That jetty is exactly where a water taxi comes alongside.
The hotel's heated saltwater pool sits a short walk up from the jetty, drawing its water straight from the bay it overlooks.
Beaulieu is tucked in the Baie des Fourmis between Nice and Monaco — roughly 20 minutes from either by water taxi in normal conditions.
La Réserve de Beaulieu describes itself as standing on the shores of the sea, and unlike several neighbours on this coast, it means it literally — the jetty is a working part of the hotel, not a marketing line.
The Basse Corniche through Beaulieu is scenic but slow at peak times. Arriving at the hotel's own jetty is the shortest route in, and matches the waterfront setting the hotel is built around.
A saltwater pool filled from the bay, gardens facing the Tête de Chien headland, and the sheltered Baie des Fourmis make Beaulieu one of the calmer stops between Nice and Monaco.
