And you have set your location on this site as Santa Pola :>)
OK, so here are some things. Sincere apologies if you know all this.
Whilst there is no Brit community as such in SP, there are a few (maybe three) places that have intercambio idiomas - in theory. In practice a lot of chat is in English but that can be useful at times. You can learn and practice Spanish elsewhere :>) Contacts can be helpful.
There are two St James bars. One is at the seafront area along Av Granada. The other is near the castle - this has (or had) language exchange meetings. Can't be sure as I am not there now. Another venue is at the Ave Maria bar in the Playa Levante area.
I used to go the AM a lot. Along Av Granada is a bar called Laico (dos). The first Laico is by the castle. If you go to Laico dos, mention me - also at Ave Maria. Round the corner from AM is the Good Mood bar - please mention me there too :>)
The Spanish courses run by the Cultural Centre are really good value. Two sessions per week - dirt cheap. There are intensive courses in Alicante - for example from zero to B2 in three months. More expensive but, in my view, well worth it.
The windmill that can be seen from the boats is really worth the walk. You can get most of the way by car. There is a walkway right out over the edge of the cliff.
Most people omit the central area, away from the sea, but there are great walks and cycle trails there - lots of olive groves etc.
Glad you like it. I hope people remember me.
Cheers.
