If you're planning a beach holiday on the Costa Blanca, the best beaches in Dénia might just be the finest lineup of sand, rock, and crystal water you'll find anywhere on this stretch of coast. I've been living here for a decade, and I still get a quiet thrill watching the sea change colour from jade to deep blue as you round the headland below the Montgó. Dénia is unusual — it has two completely different coastlines on either side of the port, each with its own personality. Give me five minutes and I'll tell you exactly where to go, what to expect, and how to get the best out of each one.
The Two Coastlines: Las Marinas vs Las Rotas
This is the single most important thing to understand about Dénia's beaches, and almost no travel site explains it properly.
Las Marinas stretches north of the port — roughly 12 kilometres of wide, flat, sandy beach divided into named sections: Punta del Raset, Les Deveses, L'Almadrava, and La Marineta Cassiana. These are your classic, family-friendly Mediterranean beaches. The water gets deep gradually, making them perfect for kids. You'll find chiringuitos (beach bars), sun lounger rentals (around €10–12 for two beds and a parasol in June), showers, and lifeguards through the summer months. Les Deveses, at the northern end near El Verger, is the wildest and least developed — great if you want space and don't need facilities.

Mostly rock and pebble coves, with dramatically clear water that snorkellers and freedivers absolutely love. No sunbeds here, no chiringuitos — just towels on flat rocks, sea urchins clinging to the walls below the waterline, and water so clear you can count the fish. There's a small sandy strip called Platja de les Rotes at the northern end (closest to town), which tends to fill up quickly in July and August.

June Beach Conditions in Dénia
June is arguably the best month for beaches in Dénia. The sea temperature has warmed to around 22–24°C — genuinely comfortable for swimming. The crowds haven't reached August levels yet. You can still find a sun lounger without a fight. The water is at its clearest before the summer algae bloom that sometimes appears in late July. Sunrise is around 6:30am and sunset after 9:15pm, giving you an enormous window of usable daylight.
One practical note: the Levante wind can kick up in the afternoons, particularly on the northern (Las Marinas) beaches. If you're going with young children and want calm water, do your swimming before 2pm.
Getting to the Beaches
If you're staying in Dénia town or the port area, most beaches are reachable by bike. The bike lane along the coast road (CV-725) is well-maintained and flat. Rental bikes are available at several points including near the fishing port for around €12/day.
By car, all the major Las Marinas beaches have free parking (except Punta del Raset which has a paid car park at €3/hour). Las Rotas has limited street parking — come before 9:30am in June, even earlier in August.
The tourist train (Tren de la Costa) runs along the northern coast road from the centre during summer — a fun and practical option with kids.
Where to Stay for Beach Access
Staying in a holiday rental close to the coast means you can walk out with your towels in the morning and be back for a shower and a cold drink within minutes. Browse our Dénia holiday rentals — we have apartments and villas near both Las Marinas and Las Rotas, bookable directly through us.
When you book direct with JV Properties instead of through Airbnb or Booking.com, you save up to 18% — that's real money you can spend on beach bar paellas and boat trips. See all available properties in Dénia and get in touch for a personal recommendation based on which coastline suits your group best.
Final Word
Dénia's beaches don't try to be Ibiza or Benidorm — and thank goodness for that. They're varied, largely uncommercialized, and genuinely beautiful. Whether you want a sandy beach with all the facilities or a secret rocky cove with electric-blue water, this town delivers. Pick your side of the port, pack your snorkel, and go explore.
