Benidorm Island sits 3.5 kilometres offshore, a 70-metre limestone outcrop that served as a pirate lookout in the sixteenth century and a quarantine station during the cholera outbreaks of the 1800s. Today the uninhabited islet anchors a marine reserve of 3,000 hectares, its underwater geology shaped by fissures and volcanic intrusions that create swim-through caves and submerged walls dropping to 30 metres. The island's western flank holds the clearest water, visibility reaching 20 metres in summer months when coastal sediment settles. Private boat trip Benidorm options emerged as an alternative to the scheduled ferry service, which has transported day visitors since 1962 but adheres to fixed departure slots and shared passenger manifests. Charter operators now maintain a fleet ranging from eight-seat rigid inflatables to 12-metre pontoon vessels, each licensed by the regional maritime authority and equipped for routes that extend beyond the standard island return. The typical charter duration spans two to four hours, allowing time for circumnavigation, anchored swimming stops, and detours into the coves north of Punta Bombarda where the coastline fractures into vertical cliffs. The marine reserve designation, enacted in 2005, prohibits anchoring within 200 metres of the island's eastern shore to protect posidonia meadows, but permits mooring at marked buoys on the western side. Underwater topography here includes a submerged ridge at 12 metres depth colonized by groupers, octopus, and schools of gilt-head bream. Scuba operators integrate dive briefings into private boat trip Benidorm tours, with descent protocols following CMAS standards and surface intervals timed to ferry traffic patterns. Charter pricing scales with vessel capacity and itinerary complexity. Standard island returns mirror the €15 public ferry fare per adult, while bespoke routes incorporating jet ski tenders, champagne service, or extended anchorage command premiums. Operators maintain contact with harbour control at Puerto Deportivo to coordinate departure windows outside peak ferry hours, ensuring private clients avoid the midday congestion when scheduled boats carry 100-passenger loads.
