Water Sports & Sea Activities in Altea: The Complete Local Guide (2026)

If you've spent five minutes in Altea staring at that impossibly blue stretch of Mediterranean water below the old town, you've probably thought the same thing I did when I first arrived here a decade ago: I need to get in that sea. And not just for a swim. The waters off Altea's coast are some of the clearest, calmest and most diverse on the entire Costa Blanca — perfect for everything from first-time paddleboarders to experienced divers hunting octopus along the rocky seabed.

June is, frankly, the ideal month for water sports in Altea. The sea temperature has climbed to a very comfortable 22–24°C, the summer crowds haven't yet turned every beach bar into a scrum, and the morning sea conditions are typically glassy and calm. Here's everything you need to know about getting on (and under) the water in Altea this summer.

Paddleboarding (SUP) in Altea

Stand-up paddleboarding has exploded in popularity here over the last few years, and it's easy to see why. The rocky coves around Altea are largely sheltered from the prevailing winds, meaning even complete beginners can get upright and moving within twenty minutes. Altea Paddle Surf operates from the beach at Cap Negret and offers hourly rentals (around €12–15/hour) as well as guided two-hour sunrise tours that take you along the cliffs towards Albir — genuinely one of the most beautiful ways to start a morning on the Costa Blanca.

For something more adventurous, ask about the guided SUP route to the Morro de Toix headland. You'll paddle past sea caves, spot bream and wrasse beneath your board through the transparent water, and likely have the whole section of coast to yourselves before 9am.

Kayaking: The Sea Caves Route

This is my personal favourite water activity in the whole Altea area. Renting a double kayak from one of the operators near Playa del Espigó (the main beach just below the town) and paddling northward towards the limestone cliffs of Toix is an experience that genuinely never gets old. There are several small sea caves accessible by kayak that you simply cannot reach on foot — some large enough to paddle right inside, where the light turns turquoise and the sound of the sea echoes off the walls.

BlueSea Altea and a couple of other local operators run half-day guided kayak tours for around €35–45 per person, including snorkelling stops. They know exactly where the posidonia seagrass meadows are (protected, and a sign of excellent water quality) and which coves are most likely to reward you with a glimpse of a moray eel or a sea turtle.

If you prefer to go independently, a double kayak rents for roughly €20–25 for two hours. The sea conditions in June are usually manageable for confident swimmers, but always check the wind forecast — a levante (easterly) wind can build surprisingly quickly in the afternoon.

Snorkelling: Where to Go and What to See

Altea is not a sand-beach destination — and that's actually a huge advantage for snorkellers. Pebble and rock mean clear water with minimal sand disturbance, and rocky seabeds are far more interesting underwater than flat sand. The best snorkelling spots are:

• Cap Negret: Rocks on the northern end of the beach, home to sea urchins, wrasse, bream and the occasional octopus tucked under a boulder.
• Cala del Fornet: A tiny cove about 2km north of the town centre, accessible via a short coastal path. Relatively unknown, excellent water clarity, and the posidonia beds just offshore are alive with fish.
• L'Olla Beach: The pebbly bay at the southern end of Altea, where a rocky reef runs parallel to the shoreline — perfect for an easy drift snorkel with the gentle current.

Bring your own mask and fins if possible (the rental gear at beach bars is functional but rarely excellent), and go in the morning before any afternoon chop disturbs the visibility.

Scuba Diving Near Altea

For certified divers, the waters between Altea and the Peñón de Ifach at Calpe are genuinely world-class. The dive centre most locals recommend is Calpe Dive Center (a 20-minute drive), which runs regular boat dives to walls, wrecks and caverns in the marine reserve around the Peñón. Expect to pay around €45–60 for a two-tank boat dive.

Closer to Altea itself, Centro de Buceo La Olla operates from the beach of the same name and specialises in introductory dives for beginners — a great option if you've always wanted to try scuba but haven't yet taken the plunge (pun very much intended). An introductory dive costs around €50–65 including equipment.

The highlight dive sites in this stretch of coast include a World War II wreck, several dramatic walls starting at around 18 metres, and a cavern dive where the ceiling is dotted with red coral. July and August water visibility regularly exceeds 20 metres.

Sailing, Boat Hire & Charter

Altea has a proper marina — the Club Náutico de Altea — and it's one of the nicest on the Costa Blanca, with resident sailing clubs, regular regattas and several charter operators. Renting a small motorboat for the day (a 5–6 metre RIB) costs roughly €150–220 depending on the season and boat size, and allows you to access coves that are unreachable by any other means.

For those who want to feel the wind in their sails without needing a licence, several operators offer skippered sailing day trips out of the marina — typically around €55–75 per person including lunch. The standard route heads south past the Sierra Helada natural park coastline and anchors in a series of coves near Benidorm island for swimming and snorkelling. Excellent value, and a completely different perspective on the Costa Blanca coastline.

Jet Ski & Motorised Water Sports

I'll be honest — this isn't really Altea's scene, and that's part of its charm. You won't find rows of jet skis for hire on the main beach. For that kind of thing, Benidorm (20 minutes south) has everything you could want. Altea deliberately keeps the noise level down, which is one of the reasons the water stays so clear and the atmosphere stays so relaxed.

That said, parasailing and banana boats do operate from the beach in high summer, and there are a couple of operators who can arrange jet ski hire from the marina for those who want it.

Practical Tips for Water Sports in Altea

• Best time of day: Early morning (before 10am) for calmest conditions and fewest people. Afternoon winds can pick up from around 2–3pm in June.
• Water temperature in June: 22–24°C — comfortable without a wetsuit for most activities.
• Parking: The Paseo del Mediterráneo car park near the beach is the easiest option. See our complete guide to getting to Altea for full transport options.
• Book ahead in July/August: Kayak and SUP tours sell out weeks in advance in peak season. June is much easier.
• Sunscreen: Use reef-safe sunscreen. This is a protected marine environment and the locals take it seriously.
