Alicante’s old center wraps around Mount Benacantil, with the castle above and the Mediterranean beside the Explanada. A hotel near Postiguet beach is a different stay from one on the long Playa de San Juan.
The Santa Cruz lanes climb below Santa Bárbara Castle. At their foot, the old town holds the Basilica of Santa María, the Co-Cathedral of San Nicolás and small squares. El Barrio has bars that stay busy late, so look at the street before you pick a room.
The Explanada de España runs along the port, and Postiguet beach is just past the old town. Mercado Central and the Luceros tram stop are farther inland. The main rail station is near Avenida de Salamanca, which suits arrivals from Madrid and Murcia.
Playa de San Juan is a longer, more open beach north of the center. The TRAM links it with Luceros and the coast toward Benidorm, but dinner in town means a ride back. Families with mostly beach days may prefer to stay here.
Spanish and Valencian are both spoken. The old center and seafront are walkable, but Santa Cruz and the castle approach are steep. Take the TRAM to San Juan or along the coast. The C6 bus runs from Alicante–Elche airport to central stops.
