If you've ever hovered face-down over a sea-grass meadow while a shoal of bream parts around you like a slow-motion curtain, you'll understand why Cap de Sant Antoni is one of the most talked-about snorkelling and diving spots on the Costa Blanca. I've been living in Jávea for ten years now, and this headland — jutting out dramatically between Arenal beach and the quieter coves to the north — never gets old. June is honestly one of the best months to get in the water here: visibility regularly hits 15–20 metres, jellyfish haven't arrived in force yet, and the water temperature is already a very comfortable 22–24°C.
Whether you're a complete beginner who just wants to poke around the rocks with a mask and snorkel, or a certified diver looking for walls, caves and posidonia meadows, this guide covers everything you need to know.
Why Cap de Sant Antoni is Special
Cap de Sant Antoni is a marine reserve — the Reserva Marina del Cap de Sant Antoni, to give it its full name — and that protected status genuinely makes a difference. You'll see species here that have been fished out elsewhere: large grouper (mérou), moray eels threading through crevices, octopus tucked under flat rocks, and clouds of rainbow wrasse. The cape itself is made up of dramatic limestone cliffs that continue underwater, creating ledges, overhangs and small caves that divers love. On a calm June morning, the water at Cala del Portitxol — just inside the reserve — is so clear it looks like someone forgot to add the sea.

Cala del Portitxol is the entry point most people use. There's a small parking area (arrive before 9am in June — it fills fast), a simple chiringuito, and the snorkelling literally starts as soon as you wade in. Swim left along the rocky shoreline and you'll find sea urchins, starfish and the beginnings of the posidonia meadow within five minutes. The water is rarely more than 4–6 metres deep close in, which makes it perfect for kids and beginners.
La Barraca — accessible by a short path from the lighthouse road — is better for more confident swimmers. The bottom drops away more quickly here, and you're more likely to encounter larger fish. I've seen octopus here more times than I can count.
Cala Blanca, slightly further around the headland, requires either a boat or a 20-minute walk, but the isolation means you'll often have the cove almost entirely to yourself. The underwater rock formations here are genuinely dramatic.
Insider tip: Always snorkel with the sun behind you when possible — the light penetration into the water makes everything much easier to see. Late morning (10am–12pm) tends to be ideal at Cap de Sant Antoni.
Diving at Cap de Sant Antoni: What to Expect
The cape offers some of the best diving in the entire Costa Blanca region. The most famous sites include:
El Correu — a wall dive that drops to around 28 metres, with large grouper, moray eels and occasional barracuda. The posidonia wall here is beautiful in June light.
La Cueva del Llop Marí (the Cave of the Monk Seal) — no monk seals left sadly, but this cavern dive is atmospheric and genuinely impressive. Maximum depth around 18 metres, suitable for Open Water divers.
Las Puntas — a series of rocky pinnacles with good current at certain times, attracting pelagic fish. Best for Advanced Open Water and above.
Visibility in June is almost always excellent — 15 metres on a bad day, 20–25 on a good one. Water temperature sits between 22°C and 24°C through June, rising towards 26°C by August.
Dive Centres in Jávea
You don't need to bring all your own kit. Jávea has a handful of well-established dive centres that run boat trips out to the cape daily in summer:
Jávea Diving (Dive Academy Jávea) is based at the port and has been operating for over 15 years. They offer everything from discover scuba sessions for absolute beginners to PADI instructor courses. Boat trips to the cap run every morning from around 9am.
Costa Blanca Divers also operate from the port area and have a particularly good reputation for guided snorkel tours — useful if you want expert company without needing a full diving certification.
Prices in 2026: expect to pay €45–60 for a two-tank boat dive (including equipment hire), €25–35 for a guided snorkelling tour. Prices are slightly lower if you book direct with the centres rather than through hotel desks.
Getting to Cap de Sant Antoni
From the Arenal (Jávea's main beach), it's about a 10-minute drive around the cape to the main snorkelling access points. Follow the signs towards the Far de Sant Antoni (Sant Antoni lighthouse) — you can't really miss it. The road becomes narrow near the lighthouse, so don't bring a large vehicle.
Parking gets very busy from mid-June onwards. My strong advice: arrive before 9am, or come after 5pm when day trippers start leaving. There's no public bus to the cape itself, though Jávea's urban bus serves the Arenal end.
Alternatively — and this is genuinely the best way to experience the cape — hire a kayak or paddleboard from Arenal beach and paddle around. It takes about 40 minutes at a gentle pace and you can drop anchor (or your paddle) wherever looks good.
June Conditions: Is This a Good Time to Come?
Absolutely, yes. June is my personal favourite month for water sports in Jávea. Here's why:
- Water temperature: 22–24°C — warm enough without a wetsuit for most people, though a 3mm shorty makes longer sessions more comfortable
- Visibility: routinely 15–20m, often more after a calm spell
- Crowds: noticeably less busy than July and August — parking is manageable before 9:30am
- Jellyfish: usually not a significant issue in early-to-mid June (they tend to arrive in July)
- Wind: the Tramuntana (northerly) and Llebeig (south-westerly) both pick up in late June — check local forecasts and avoid snorkelling or diving if there's more than Force 3
The best weather resource for Jávea's waters is the Puertos del Estado app or website — it gives wind and wave forecasts specifically for this stretch of coast.
What to Bring
- Mask, snorkel and fins (hire available at most beaches, but bringing your own is far better)
- Water shoes — the entry points at Portitxol and La Barraca are rocky
- Reef-safe sunscreen — important both for your skin and for the marine reserve
- Underwater camera or waterproof phone case — the marine life here is genuinely worth photographing
- Water and snacks — the Portitxol chiringuito has cold drinks but limited food
- A 3mm shorty wetsuit or rash vest if you plan to be in the water more than an hour

A Final Note from Someone Who Lives Here
Cap de Sant Antoni is one of those places that rewards patience and early mornings. Go at 8am when the light is still low and golden, the water is calm, and you have the cove largely to yourself. Float over the posidonia meadow, watch the bream catching the light, and you'll understand why people come to Jávea once and end up coming back every year for the rest of their lives.
