Dalt Vila is very well preserved and the walk is beautiful. Originally called Ibosim and founded by the Phoenicians, once one of the most important coastal cities in the Mediterranean Dalt Vila has been added to by consecutive occupiers throughout the years. The last addition was the Renaissance defensive walls that surround it, which Kings Charles I and Philip II of Spain had constructed to defend against the French and the Ottomans.

There are surprises and amazing photo opportunities everywhere; this enormous melting pot of history, aged buildings and walls defy you to not find something of interest. You're better off on foot, in sensible shoes, exploring the narrow, winding, steep cobbled streets and magnificent views from the breaks in the high ramparts and the vast terraces at each level.

In the city, there are many climbs, stairs, small streets and impressive viewpoints of the city and the coast. Within the Old Town, you can eat something, go to museums and the cathedral. Taxi from Sant Antoni (San Remo hotel) to the Cathedral at the top of the Old town hill was €28 (€24 back). Even the taxi driver advises to start at the top and walk down. 

Lovely views of the ocean and the port (there was some small boat trips available from the port that would be worth checking out)
