Parque La Marjal, Alicante.

• Bus: Lines 21 and 38
• By car: Free on-street parking along Avenida de las Naciones and surrounding streets — rarely a problem outside peak summer weekends

Not what most people expect from a city park. Parque La Marjal was originally built as a flood-control reservoir — which explains why it looks nothing like a typical urban green space.
The centrepiece is a large lake surrounded by reeds and aquatic plants. Wooden bridges and gravel paths wind around the water. Ducks, herons, turtles, and dragonflies are regular residents — not occasional sightings. On a quiet morning it genuinely feels removed from the city despite being a 5-minute walk from Playa de San Juan beach.

• Wide open lawns sit alongside shaded rest areas. The whole design is flat and unhurried — the kind of place where you arrive for 30 minutes and stay for two hours.

More than the lake suggests. A few things worth knowing:

• Picnics — open lawns, plenty of shade, and benches near the water. One of the better free picnic spots near San Juan beach. Dogs are not allowed inside — which keeps the grass genuinely clean, especially good if you have toddlers.
• Birdwatching in Alicante — herons, ducks, moorhens, and dragonflies are regular residents. The wooden observation decks give you a proper view without disturbing anything. Bring binoculars if you have them.
• Family time — modern playgrounds set near the lake, scenic bridges the kids will want to cross multiple times, and no traffic anywhere near the park.
• Walking and jogging — flat circular gravel paths around the full perimeter. Locals use them every morning. Short enough for a relaxed loop, long enough for a proper jog.
• One important rule: No dogs allowed inside the park. Signs at every entrance — don't try to sneak one in.

The basics are covered — but worth knowing what's there and what isn't:

• Drinking fountains — several throughout, no need to bring water
• Shaded seating areas and modern children's playgrounds
• No public toilets inside the park — use facilities at the nearby beach or cafes on Avenida de las Naciones before you enter
• Entry: Free
• Opening hours: 09:00–21:00 winter / 09:00–22:00 summer. Hours can vary on public holidays — check the gate on arrival.

Best time to visit Parque La Marjal: Early morning or evening after 18:00 in summer — cooler, quieter, and the light on the lake is worth seeing. Sunset here is genuinely one of the nicer free views in the San Juan area.
Important rules:

• No dogs — strictly enforced at every entrance
• No cycling inside the park — perimeter only
• Local tip: The park is a 5-minute walk from Playa de San Juan — combine both in the same afternoon. Beach first, lake after. Or the other way around if you want shade first.

Most people staying near San Juan beach never make it to La Marjal — it's right there and most of them walk straight past the entrance.
That's their loss. This is one of the few places in Alicante where you can sit next to a lake, watch a heron land three metres away, and hear nothing but water and birds — while being a short walk from one of the busiest beaches on the Costa Blanca.
It works for everyone. Families come for the playgrounds and the turtles. Joggers come for the morning loops. Couples come for the sunset. Locals come because it's free, quiet, and genuinely beautiful without making a fuss about it.
No entry fee. No crowds. No dogs. Just a lake, some wildlife, and more time than you planned to spend there.
