The Avenida Ejércitos Españoles is part of the longest road in Calpe, the dual carriageway which stretches from the southern entry to Calpe (with the boat) all the way to the Salinas and the coast road to Moraira. The Clínica Britannia is in the built-up area between Plaza Central and the Calle Niña (the “dry river bed”), opposite an Opal car garage.
Parking is hard in Calpe, but (except in August) you can usually park in the Plaza Central car park and walk down the road to the clinic.
There is a signpost on the pavement, and a prominent display by the bell. The clinic is on the first floor. As well as the stairs, there is a lift.
