Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Tascó Gros presents a varied underwater topography, beginning with its two distinct islands, Tascó Gros and Petit Tascó, separated by a shallow channel. A channel, reaching a maximum depth of 5 meters (16 ft), acts as a vibrant corridor of marine biodiversity, easily explored for macro-organisms.
Multiple routes are available to divers; some opt to circumnavigate the main islet, while others focus on specific sides, either staying shallower or venturing into deeper sections. A dramatic vertical wall defines the north side, extending alongside Carall Bernat, adorned with abundant red and white gorgonians. Further along, a transition leads to a platform composed of large rock blocks, forming numerous cavities that offer shelter for various fauna.
On Petit Tascó's south side, beyond 22 meters, divers encounter more rock formations, leading into a canyon that plunges to a maximum depth of 40 meters (130 ft). Canyon walls are similarly draped with colorful gorgonians, creating a visually stunning landscape.
While offering deeper recreational profiles, this site also features shallower segments, making it adaptable for various certification levels, with many routes remaining above 30 meters (100 ft).

Best Time to Dive
To maximize visibility and overall dive comfort at Tascó Gros, planning during the warmer months, typically from May through October, is advisable. During this period, wave heights are generally lower, averaging around 0.7 to 1.0 meters, which contributes to clearer water and calmer surface conditions. Air temperatures during these months range from approximately 18°C (64°F) in May, peaking around 26°C (79°F) in July and August, then gradually cooling to 19°C (66°F) by October. Rainfall is also notably minimal, often less than 2 mm per month, reducing runoff and particulate matter in the water. While diving is possible year-round with good dive scores consistently reported, conditions are often more exposed to currents and the tramuntana wind. Divers should consult local forecasts closely, as these factors can significantly impact the site's suitability regardless of the season. Less rain generally correlates with better potential for visibility.

Dive Experience & Conditions
Entering the water at Tascó Gros, often via boat to an anchor buoy on its north side, places divers directly into an exposed environment. Conditions here can vary significantly, heavily influenced by local currents and strong tramuntana wind. While some sections are suitable for less experienced divers within the 30-meter range, overall exposure and potential for strong currents mean it's often approached as an advanced dive, particularly when exploring deeper profiles down to 40 meters. Circumnavigating the islet, a common itinerary, requires careful attention to current strength. Visibility, while generally good, can be affected by swell or wind-driven conditions. Expect dynamic conditions that reward divers with experience in drift diving or those comfortable with planning around environmental factors. Local guidance is highly beneficial to navigate the best route for prevailing conditions.
Dive Difficulty & Safety Guidelines
Primary safety consideration at Tascó Gros involves managing strong currents and waves, as it's an exposed dive site. Conditions here are particularly susceptible to the tramuntana wind, which can rapidly alter the sea state. Divers should always assess current strength and prevailing weather before entering the water, making sure to plan dives for suitable conditions. Due to potential dynamic water movement, maintaining good buoyancy control and staying close to your buddy are essential. It's prudent to carry a surface marker buoy (SMB) for all dives, especially if there's a possibility of drift. Reviewing your dive plan with a local guide is highly recommended, as their expertise can mitigate potential risks associated with the site's exposed nature.

Keep an eye out for substantial groupers patrolling the deeper sections. Moray eels are also frequently observed within the rocky hideaways. For those scanning the blue, there's potential to spot pelagic species like barracudas, ocean sunfish, and the site's highlight, eagle rays, which glide through the open water.

Tascó Gros ranges from around 15 m / 49 ft to a maximum depth of about 40 m / 131 ft. Many recreational routes stay shallower, often within 30 m / 98 ft, but the deeper profile and exposed conditions make local guidance important.
What kind of marine life can I expect to see?
You're likely to encounter large groupers, moray eels, and diverse macro-organisms like nudibranchs among the rocks. Pelagic sightings can include barracudas, ocean sunfish, and particularly eagle rays.
Is Tascó Gros suitable for beginner divers?
Some shallower sections may be accessible with local guidance, but Tascó Gros is better suited to divers with experience in deeper and more exposed conditions. The site can reach about 40 m / 131 ft, so beginners should not treat the full profile as a simple entry-level dive.
What are the typical water conditions?
Tascó Gros is an exposed site, meaning it can experience strong currents and waves, particularly influenced by the tramuntana wind. Visibility is generally good, but conditions vary, requiring careful dive planning.
When is the best time of year to dive here?
The period from May to October generally offers the most favorable conditions with warmer air temperatures and calmer seas. However, good diving is possible year-round with appropriate planning for currents and wind.
Are there any specific hazards I should be aware of?
The main hazards are strong currents and waves, due to the site's exposed location. Always check local forecasts and current reports, and be prepared for potentially dynamic conditions.
