Denia Castle
Seen from the sea, the castle stands out sharply above the harbour and the old town. Moor at Marina de Denia or the harbour and walk up to the fortress for a view over the whole bay, with the Montgó behind it.

11th century
Denia Castle
Of Moorish origin, the castle crowns the headland that separates the harbour from the town — the first postcard view of Denia for anyone arriving by sea.
753 m
Montgó Natural Park
The Montgó massif drops straight into the sea between Denia and Javea and shadows the whole coastline here — a backdrop unlike anywhere else on the Costa Blanca.
~50 nm
Gateway to the Balearics
Denia is the closest mainland port to Ibiza and Formentera — around fifty nautical miles separate its harbour from Ibiza bay.
April – October
Sailing season
This stretch of the Costa Blanca has a mild climate that stretches the season well beyond the height of summer, with calm seas and good visibility for snorkelling.

Boat trips from Denia call at coves like this one
Denia pairs a hilltop castle with sea views, a natural park that tumbles into the water, clear-water coves and some of the best food on the Costa Blanca. These are the experiences that make a route from Denia worth remembering.
Seen from the sea, the castle stands out sharply above the harbour and the old town. Moor at Marina de Denia or the harbour and walk up to the fortress for a view over the whole bay, with the Montgó behind it.
The rocky shoreline east of the harbour, dotted with small coves of clear water and seabeds of real ecological value. Anchoring off Las Rotas for a swim or a snorkel is one of the easiest, most rewarding outings from Denia.
The Montgó Natural Park drops into the sea between Denia and Javea. Cova Tallada, a cave carved into the rock right at the waterline, is reachable only on foot via a demanding trail — or, far more comfortably, by anchoring the boat right in front of it.
A short way from Denia, Cap de Sant Antoni and Cap de la Nau frame Javea bay. Their cliffs and coves — Granadella among them — are best enjoyed hugging the coast by boat rather than by road.
Denia is a UNESCO Creative City of Gastronomy. Red prawns, arroz a banda and fish straight off the boat are unmissable after a day at sea, at any of the restaurants along the harbour.
Denia is the closest mainland harbour to the Pityusic Islands. With a boat set up for open-water passages — and ideally an experienced skipper — it is the most direct starting point for a crossing to Ibiza and Formentera.
From the rocky shore of Las Rotas to the capes off Javea, or the long crossing to Ibiza and Formentera: three routes covering everything Denia has to offer, whether you sail with a skipper or take the helm yourself.
Practical information for planning your route from Denia: when to go, where to anchor, which harbours to use and what qualifications you need — including the crossing to Ibiza and Formentera.
If a crossing to Ibiza or Formentera is on your plan, pick a window of several days of settled weather — the return leg needs the same stable conditions as the outward one.
In calm seas the seabed at Las Rotas is easy to see from deck — the best guide for choosing where to drop anchor.
If you're setting off for Ibiza or Formentera, leave Marina de Denia with some margin — paperwork and refuelling take longer in high season.
If you only have one day, consider the fast ferry to Ibiza instead of a private-boat crossing: at around fifty nautical miles, a there-and-back trip in a single day is unrealistic except in very fast boats.
