In the early 2000s many Russians acquired villas around Costa Brava, inflating restaurant prices, and bringing many expensive cars to the region.
Costa Brava's main airport is Girona-Costa Brava airport. Ryanair operate flights to the airport from several destinations in Europe and Morocco all year. Other airlines include Thomas Cook Airlines, Thomson Airways and transavia.com (all seasonal). Alternatively, you can fly into Barcelona-El Prat airport. Airport shuttles operate between Girona-Costa Brava airport and the majority of the resort cities, Barcelona and Girona city centre.
Girona/Gerona/Costa Brava airport, or by train from Barcelona. There are now buses to Lloret from the airport at €9.You'll find them on the Girona airport internet site. Because of the narrow streets, coaches will often drop people little walk from their hotels. A little more expensive at just over €10 is the (shared) http://www.barcelonatransfers.com which is direct and will drop you off and pick you up at your accommodation. There are also a number of official pick up points round town for bus (shuttle coaches) which you will probably leave from rather than your hotel. You must confirm pickup with the shuttle service up to 72 hours before going home.
If you want to explore a lot of the coastal cities then renting a car is your best option. There is regular bus service between the towns but nothing compares driving along and stopping where you like.
The unknown gem of the Costa Brava is Tossa de Mar. This beautiful little fishing village is one of the least developed on the northern Spanish Mediterranean coast. Tossa is still a fishermen's town, with the quaint very-narrow cobblestoned streets, white houses, and beautiful coastline. Tossa also boasts some very well-preserved medieval ruins -- including walls and towers which protected the town between the thirteenth and sixteenth centuries.
If you like casinos and more luxurious accommodations, go to Lloret de Mar. However, if you prefer the less developed beaches, and don't mind less ostentatious accommodations, Tossa de Mar is for you.
There are scuba diving outings to the "Illes Medes" (Medes Islands) National Reserve Park from L'Estartit. Cadaques also has various dive shops to explore the area.
The Rovers Return - A lovely British pub, serves nice food and a lovely pint. Also recommended for late nights as the hosts are excellent company!
