Alicante Harbour is a real 'Millionaires Row' of expensive yachts which are either privately owned - or even advertised for sale (if you have a spare 1 million euros you should be able to find something that takes your fancy!).

Alongside the harbour is a variety of Spanish restaurants and bars - all reasonably priced and worth a try.  Alicante beach is very nice, and within five minutes walk of the Harbour.

You can also walk in to Alicante City Centre (five-ten minutes from the Harbour) to make a day of it.
