The city is located on the Cantabrian coast in northern Spain. In addition to the many adjacent beaches Santander is protected by the nearby mountains whilst the high altitude Picos de Europa mountain range is less than 90 minutes drive.

The city's airport (only a 15 minute journey to the conference hotels) has direct flights to Madrid, London, Rome, Brussels, Edinburgh & a number of other locations. Santander is only a little more than a one hour drive from Bilbao, which offers considerably more direct flights. 

Gaudi's "Capricho", in Comillas, & the medieval town on Santillana del Mar are also only a short drive away. 
Santander perfectly combines tradition and modernity. It is a small city of ~175,000 people, surrounded by the sea & adjacent to a large bay. Five beaches of the highest quality, golf courses, marinas, and a very high standard of gastronomic offering, based on the quality of local raw materials, make Santander an ideal place to visit.
