If you're planning a family holiday on the Costa Blanca, Dénia with kids is genuinely one of the best decisions you'll make. I've been living here for a decade and I still see the look on children's faces when they spot the castle rising above the town, or when they find their first sea urchin in the rock pools at Les Rotes. This place was made for families — and September is honestly the sweet spot: the sea is warm (26–28°C), the crowds have thinned, and prices are noticeably lower.
Here's my honest, boots-on-the-ground guide to keeping kids of all ages happy in Dénia.
Beaches That Work for Families
Not all beaches suit kids equally, so let me save you some legwork.

Find rentals →Playa de l'Almadrava is my top pick for families with young children. It's wide, sheltered, has gradual entry, and there's a beach bar right there (the Chiringuito Almadrava) where you can get a cold Mahou and the kids can have a granizado. Toilets, showers, sun lounger hire — everything you need. It sits on the northern edge of the Las Marinas coast, about a 10-minute drive from the town centre.
Las Marinas itself is a long, calm stretch of sandy beach with lifeguards on duty throughout summer and into September. The shallow water is perfect for paddling toddlers. Parking is easy along the N-332 service road, and there are several beach bars and supermarkets nearby if you forgot sunscreen (it happens to everyone).
For slightly older kids who want adventure, Les Rotes rock pools are unmissable. Pack some water shoes and a small net — kids can spend hours hunting for crabs, blennies and starfish. It's not a swimming beach for toddlers, but for kids aged 6+ who like exploring, it's magic.
Dénia Castle: Kids Actually Love It
I know what you're thinking — dragging children around a historical monument. But Dénia Castle (Castillo de Dénia) is different. The views alone sell it: you can see all the way to Ibiza on a clear day, and kids find that genuinely impressive. The castle grounds are open and spacious, so little ones can run around without you stressing.
Inside the Archaeological Museum, there are interactive elements and the exhibits are well laid out. Entry is around €3 for adults and free for children under 12. Allow 90 minutes and bring water — the walk up from the old town takes about 15 minutes and it's exposed in the sun.
Tip: Go early morning (opens at 10am) or after 5pm in September to avoid the heat.
Molino de Papel: A Hidden Gem for Curious Kids
Not many visitors know about the Molino de Papel (Paper Mill Museum) near the Río Molinell. It's a beautifully restored 15th-century paper mill with hands-on workshops where kids can make their own paper. It's free to visit and the staff are brilliant with children. This is the kind of place locals bring their own kids — always a good sign.
Water Parks & Outdoor Fun
Aqualandia in Benidorm is only 50 minutes away and is genuinely one of Europe's best water parks — worth the trip if you have older thrill-seekers. But honestly, in September you might find the smaller, free option of the natural pools at Font Salada (near Oliva, 20 minutes north) just as satisfying. It's a freshwater spring surrounded by reeds, and kids absolutely love it.
For boat trips, Dénia Dolfins and Mundo Marino both run family-friendly excursions from Dénia harbour. The glass-bottom boat to the Cabo de San Antonio marine reserve is a favourite — kids press their faces to the glass watching sea bream and octopus below. Trips run from around €18 per adult and €10 for children. Book a day ahead in September — they still fill up.
Mini Golf, Go-Karts & Evening Entertainment
The Mini Golf Dénia on Avenida de la Mar (near the Las Marinas beach area) is a reliable crowd-pleaser for ages 4 and up. It's open until late, well-lit, and cheap — around €5 per person. Great for that post-dinner slot when you're not ready to go home but the kids need to burn off the last of their energy.
For go-karts, Karting La Canyada near Ondara (15 minutes inland) has junior karts from age 5 and adult karts too. It's not glamorous, but kids lose their minds for it.
In the evenings, the Paseo Marítimo (the main seafront promenade) comes alive in a gentle, family-friendly way. There are usually street performers, ice cream stalls (Heladería Los Portales near the port does the best turrón ice cream), and space to just wander. It's very Spanish, very relaxed, and genuinely lovely.
Eating Out with Kids in Dénia
Spanish culture is brilliantly child-friendly — kids are welcome everywhere and nobody gives you the look if yours is running around at 10pm. For family meals, La Seu on Calle Loreto does excellent pizzas and pasta that fussy eaters usually accept without negotiation. Restaurante El Raset near the port is a step up — their arroz a banda (rice cooked in fish stock) is one of the best things you'll eat on the Costa Blanca, and the kids' menu is decent too.
For quick lunches near the beach, the chiringuitos along Las Marinas do bocadillos, fresh fruit and cold drinks at reasonable prices.
Practical Tips for Families in Dénia
- Car: You need one. Dénia is spread out and buses are infrequent. Most holiday rentals have parking.
- September timing: Perfect. Sea temperature peaks, school crowds gone, restaurants have availability.
- Supermarkets: Mercadona on Avenida del Montgó is well-stocked. Open 9am–9pm.
- Pharmacies: There are several in the old town and along Las Marinas — great for sunburn cream and insect repellent.
- Medical: Hospital de Dénia (now the Marina Salud clinic) has a paediatric unit for peace of mind.
Where to Stay in Dénia with Kids
For families, a self-catering apartment or villa beats a hotel every time — you've got a kitchen for the nights when kids are too tired to go out, a washing machine (essential), and usually a private pool. Staying near Las Marinas puts you closest to the family beaches. The old town area is charming but better for couples.
