In the morning, the bulk of Montgó is still in shadow and the smell of sea salt drifts up from the harbour. That is how a beach day starts in Dénia, and choosing among the best beaches in Dénia is, above all, deciding what kind of day you want.
This seafaring city in Alicante has some 20 kilometres of coastline with two very clear faces. In the north, long, fine sand for going with children. In the south, at Les Rotes, clean rock and transparent water for diving.
Before or after your swim, it is worth getting lost in the streets of Baix la Mar, the old fishermen’s quarter, and climbing up to the castle to see the bay from above.
We go through the essential beaches and coves, with a concrete plan for each one.
The best beaches in Dénia in the north
The north coast is a succession of sandy beaches that link up all the way to the border with Oliva. Shallow water, facilities and plenty of space.
Les Marines, the family classic
A few kilometres from the centre, Les Marines is the best-known sandy beach in the city. It is long, easy to reach and has every facility, including the 2026 Blue Flag.
There is a bus stop very close and wooden walkways down to the water’s edge. (And yes, watching Montgó outlined against the sea at sunset is one of the best parts of the day.)
The plan: sandcastles in the morning, a nap in the shade and a barefoot walk along the shore when the sun goes down.
Els Molins, fine sand and a quiet atmosphere
Heading north, Els Molins keeps the fine sand and shallow water of Les Marines, with a somewhat more relaxed atmosphere. It also has a Blue Flag this year.
The plan: if you travel with small children, it is a good alternative when Les Marines is packed in August.
L’Almadrava, the memory of tuna fishing
L’Almadrava combines sand with stretches of pebbles. Its name recalls the almadrabas, the fixed nets once used to catch tuna on this coast.
The plan: a swim in mid-morning and an unhurried rice dish at one of the nearby restaurants.
Les Deveses, the most natural in the north
At the northern end of the municipality, right next to Oliva, Les Deveses is the sandy beach with the most natural look in Dénia. It has a Blue Flag in 2026.
It is wide and less built up, and attracts those looking for calm away from the summer bustle. On windy days you can also see windsurf sails.
The plan: bring a book and stay late. Here the horizon is clear and the pace is different.
The southern coves: Les Rotes
From the harbour, heading towards Cabo de San Antonio, the sand disappears and the rock begins. It is another world: clear water, seabeds full of life and fewer parasols.
Marineta Cassiana, the only sand in the south
It is the first beach after leaving the harbour towards Les Rotes and the only sandy one on this side. A breakwater protects it and creates a very calm sheet of water, with a gentle slope.
A pedestrian promenade by the sea connects it with the harbour. It has a Blue Flag in 2026.
The plan: perfect for an early swim with children before the heat sets in.
Cala del Trampolí, snorkelling in the marine reserve
The Cala del Trampolí is a rocky cove inside the Cabo de San Antonio Marine Nature Reserve. Its name comes from the fixed platform on the rock from which people jump into the water.
The seabed has Posidonia meadows and plenty of life, so it is one of the best places in the city for snorkelling. Scuba diving requires prior authorisation.
The plan: mask, snorkel and an hour floating over the Posidonia. Afterwards, lie on the rock to dry in the sun.
Punta Negra, rock and deep water
A little further along the Les Rotes road comes Punta Negra, a headland of grey rock surrounded by Mediterranean vegetation. The atmosphere is intimate and the water gets deep quickly, in an intense blue.
It is also on the 2026 Blue Flag list.
The plan: bring a mat for the flat rocks and look for a quiet corner.
Les Rotetes, the sheltered little cove
Les Rotetes is a tiny cove much loved by the people of Dénia. Being protected from the open sea, on windless mornings the water is like glass.
It is a good place to try paddle surfing for the first time or to follow the rock fish with your mask.
Practical tip: the north (Les Marines) has fine sand and is ideal for families; the south (Les Rotes) is rocky and perfect for diving. For the southern coves, pack some water shoes: walking on the stone is much more comfortable.

Best beaches in Dénia: getting around and when to go
You can reach all of them easily by car or bicycle. The Denibus city buses have lines to Les Marines and to Les Rotes.
In summer, the final stretch of Les Rotes is closed to traffic from 8:00 to 20:00. In 2026 the closure ran from 13 June to 13 September, with free parking at the entrance and a free tourist train to the end of the road. Public transport can still get through.
For a swim with plenty of room and a good water temperature, choose June or September. The harbour restaurants are quieter and the city is enjoyed at a different pace.
The perfect one-day plan: a morning of snorkelling at Les Rotes, lunch in Baix la Mar and an afternoon on the sand at Les Marines.
At which of these beaches would you plant your parasol this summer?
