Discover Alicante City: Old Town, Castle and Sea

Castillo de Santa Bárbara defines Alicante’s skyline. The fortress stands high above the centre, with sweeping views over the harbour, rooftops and coast. Don’t treat your visit as just a photo stop: its courtyards, walls and exhibition spaces bring its strategic location to life. The path uphill is steep and sunny. The lift near Postiguet Beach is more convenient, as is a shuttle if one is running on the day of your visit. Access and opening hours may change with the season; check the latest information on the tourism office’s official castle page.

The walking route through Santa Cruz goes up narrow streets and steps. Good shoes, water and breaks are recommended, especially in the warmer months. If you’re travelling with a stroller or have limited mobility, check the step-free access options in advance rather than assuming the steep route through the old town will be suitable.

Below the castle lies Santa Cruz, a residential neighbourhood of narrow streets, whitewashed houses and small squares. A walk is more pleasant early in the day or later in the afternoon. Be considerate of residents and keep doorways clear. Further down, you’ll find squares and shopping streets. The Co-Cathedral of San Nicolás and the Basilica of Santa María offer a glimpse into the city’s religious and architectural history. Interior visits depend on opening hours and services.

The Explanada de España connects the harbour with the city centre. Its mosaic pavement, benches and cafés make it a great place for a break between the old town and the waterfront. Seasonal excursions depart from the harbour; a trip to Tabarca is a day out in its own right, so plan around the timetable and weather. For a swim in the heart of the city, Playa del Postiguet lies just below Mount Benacantil.

MARQ, the Archaeological Museum of Alicante Province, tells the story of the region through archaeological finds and changing displays. MACA presents modern and contemporary art near the Basilica of Santa María. MUBAG focuses on art from the region. Check exhibitions, admission and opening hours shortly before your visit, as they can change. A museum is also a pleasant alternative when the midday sun makes a longer outdoor walk unappealing.

Postiguet is an easy walk from the centre and is ideal for a quick cool-down between sights. For more space and a longer beach stay, head to Playa de San Juan, north of the centre. The bus or TRAM makes the journey more convenient. Before swimming, check the flags, sea conditions and local notices; access and facilities may vary by season.

To compare Alicante with other coastal towns, see our articles on Benidorm, Torrevieja and Orihuela. Benidorm is a densely built-up resort, Torrevieja combines a town with salt-lake scenery, and Orihuela offers a historic old town and excursions inland. If you’re planning to continue along the coast, you can also consult our overviews of the Costa Blanca and the Costa del Azahar.

Alicante–Elche Airport is outside the city and has no direct TRAM connection to the terminal. The C-6 bus runs to the centre. Check stops, operating hours and fares with the operator for your travel date. The TRAM d’Alacant serves destinations along the coast from central stations; depending on where you’re going, it’s more like a regional railway than an urban tram. Timetables can change, so check them on the day. The city centre, Explanada, Postiguet and parts of the old town are easy to link on foot. If you’re arriving by car, arrange parking in advance: the old town’s narrow one-way streets are no place to look for a spot on the fly.

For a first day, try a route from the centre to the Explanada, through Santa Cruz and up to the castle, then back down to Postiguet. In hot weather, it’s more pleasant to reverse the timing: visit the castle and old town in the morning, spend midday in a museum or take a longer break, then enjoy the promenade and beach later. With a second day, you can add Playa de San Juan, a museum or—if a seasonal service is confirmed—a trip to Tabarca. There’s no need to cram everything into one day.

Alicante is also a good base for trips farther north. Gandia and Oliva offer a different kind of coast, while Sagunt and Xàtiva add historic towns to a road trip. Alicante itself should be more than a stopover: with its castle, old town, museums and sea, it’s easy to tailor your stay to the weather, your interests and the time you have available.

In summer, factor sun protection, water and realistic walking times into your plans. Santa Cruz is hilly and uneven in places; if you have limited mobility, check the route and alternative access options beforehand. Conditions for visiting the castle and museums, taking boat trips and using public transport vary by date. If you’re planning a beach day, set aside enough time instead of squeezing it in between two sights.

The harbour reveals another side of the city, with promenades, restaurants and berths side by side. It makes a pleasant walking link between the Explanada and Postiguet, but it’s no substitute for booking a boat trip. If you want to take a ferry to Tabarca, check the departure point, return service and weather on the day. The island has paths between the village and the coast, but opportunities for swimming and beach time depend on sea conditions and the season. Don’t plan an evening return without confirming that a service is running.

In the city centre, it’s worth wandering along the shopping streets beyond the main squares, too. Mercado Central is a striking place to visit in the morning; as a food market, it’s also part of everyday life. Check opening hours and holiday schedules in advance. When visiting, don’t take photos in the shopping areas without asking, and avoid disrupting business. If you’re looking for local products, browse here and in the surrounding streets, but don’t leave a market visit or a longer exploration to a tight time window.

With children, a varied pace usually works better than a full day of sightseeing: a short walk through the old town, a break in the shade, a castle visit using a suitable route, then the beach or a museum. The uphill walk can be tiring for young children and in hot weather; not all the neighbourhood’s paths are stroller-friendly. Make sure your day plan includes water, sun protection and an alternative for very hot weather.

Alicante is also easy to divide up for groups with different interests. While some visit the museums, others can stay by the harbour or on the promenade, then everyone can meet up again in the centre. If anyone wants to avoid long uphill walks, choose meeting points at lower levels and don’t assume the route back from Santa Cruz is step-free. Check the latest local guidance and information from the venues.

If you’re travelling onwards by train or bus, choose your accommodation and station based on your actual route, and allow time to get there with your luggage. You don’t need a rental car for the main sights in the city centre, although one can be useful for more remote destinations. On a longer road trip, you can combine Alicante city with the coast without changing your base every day. That leaves time for a relaxed evening and takes the pressure off trying to tick off the castle, a museum and the beach in just a few hours.
