If you're looking for the best Marbella snorkeling spots by boat, the choice usually comes down to two favourites: Cabopino and Estepona. Both are within a short cruise from Puerto Banús, yet they offer completely different underwater experiences. Cabopino is all about sandy, shallow coves and gentle waters – perfect for families and first-timers. Estepona, on the other hand, delivers rocky reefs, clearer water, and a more diverse marine ecosystem. This guide compares both destinations side by side, so you can pick the right spot for your group size, budget, and snorkeling skill level. All our charters include a licensed skipper, fuel, drinks, snacks, and snorkel gear – no hidden costs.
Cabopino: Sandy Shallows and Family-Friendly Snorkeling
Cabopino lies about 20 minutes east of Puerto Banús, near the famous Cabopino beach and sand dunes. The seabed here is mostly fine sand with patches of Posidonia seagrass, which attract small fish like seabream, mullet, and the occasional cuttlefish. Water depth rarely exceeds 5 metres within 50 metres of the shore, making it safe for children and weak swimmers. Visibility averages 8–12 metres from May to October. The main snorkeling area is the cove just west of the Cabopino marina entrance. There are no strong currents, and the boat can anchor right next to the snorkeling zone. If your group includes non-snorkelers, they can swim ashore to the beach club or explore the dunes. For a 2-hour charter, the Astondoa 40 (€749/2h, 9 pax) is a popular choice.
Estepona: Rocky Reefs and Rich Marine Life
Estepona, 30–35 minutes west of Puerto Banús, is the better option for experienced snorkelers. The coastline here is more rugged, with granite boulders and underwater rock formations that create natural habitats for groupers, moray eels, starfish, and even small rays. The clearest spots are Cala del Faro and Cala Cortés, two small coves sheltered from the prevailing westerly winds. Water visibility often exceeds 15 metres in summer. Depths range from 3 metres inshore to 12 metres just 30 metres out. There are no sandy beaches – access is purely by boat. The reward is a much richer biodiversity than Cabopino. Because Estepona is further from Puerto Banús, we recommend a minimum 4-hour charter to allow enough snorkeling time. The Azimut 58 Flybridge (17.6m, 12 pax) is ideal for larger groups who want comfort and speed.

Which Boat Should You Book for Snorkeling?
The right boat depends on group size and whether you want to combine snorkeling with other activities. For a quick 2-hour snorkel session at Cabopino, the Azimut 39 (11 pax, €749/2h) is the most cost-effective option. If you're heading to Estepona and want to spend the day, the Mangusta 80 (12 pax, from €4,719/4h) includes a free jet ski – perfect for exploring the coves between snorkeling stops. Smaller groups of up to 5 can use the Speedboat (7m, 6 pax) or Dubhe (8m, 5 pax), both of which are nimble and can anchor close to the rocks. All boats carry snorkel masks, fins, and wetsuits on request. If you're unsure which boat fits your plans, contact us on WhatsApp and we'll match you to the right vessel.
Best Time of Year for Snorkeling in Marbella
Snorkeling conditions vary across the year. The peak season is June to September, when water temperatures hit 22–26°C and visibility is at its best (12–18 metres). May and October are still good, with cooler water (18–21°C) but fewer crowds. From November to March, the water drops to 15–17°C and visibility can reduce to 5–8 metres due to plankton blooms and winter swells. That said, sunny winter days can still offer decent snorkeling at Cabopino if you wear a wetsuit (we provide them). Estepona tends to have clearer water in winter because its rocky seabed doesn't stir up sediment as easily. For the best experience, book a morning charter – the sea is calmest between 9:00 and 12:00, and the sun angle gives the best underwater light.
How to Combine Snorkeling with a Full Day on the Water
Many guests treat snorkeling as just one part of a longer itinerary. A typical 8-hour charter from Puerto Banús might include: a morning snorkel at Estepona's Cala del Faro, a late lunch at a chiringuito in Cabopino, an afternoon swim stop near the Golden Mile, and a sunset cruise back past the Marbella marina. The Ferretti 94 (29m, 12 pax) is spacious enough for a full-day trip with a proper dining area and sun pads. If you're on a tighter budget, the Bandido (11.5m, 8 pax) offers a more intimate experience. Whichever boat you choose, your skipper will know the best anchor spots and can adjust the plan based on weather and sea conditions. Just let us know your preferences when you book.
Frequently Asked Questions
Which is better for beginners: Cabopino or Estepona?
Cabopino is better for beginners. Its shallow, sandy seabed and calm waters make it safe and easy to snorkel. Estepona has more rocks and deeper drop-offs, which can be challenging for novices.
How long does it take to reach Cabopino from Puerto Banús?
Cabopino is about 20–25 minutes by powerboat from Puerto Banús. Estepona is slightly further, around 30–35 minutes. Both are easily covered in a 2-hour or 4-hour charter.
