There are a large number of marinas on the La Manga del Mar Menor to arrange boat trips. The Mar Menor is connected to the Mediterranean by four channels, which stop the Mar Menor (inland lake) from drying. The largest channel is called El Estacio and is the only waterway for boats wishing to visit both seas.
The Tomas Maestre marina has over 1000 moorings and a good selection of restaurants and shops, it is located close to this channel. A wide choice of boat trips, Charters and watersports are available from the marinas surrounding the Mar Menor and also on the Mediterranean side.
You can charter a boat and visit the Balearics, which are only a few hours away.
