The boat trip to Santa Clara island is a short seasonal ferry-style crossing from the harbour of San Sebastian, in Spain's Basque Country, to the small island that sits in the middle of La Concha Bay. Boats leave from the Muelle at the Puerto de San Sebastian, below the Parte Vieja, and cover the roughly 700 m to the island in about 10 minutes each way.

Seasonal boats from the harbour carry visitors to Santa Clara island for a lighthouse path, a small beach and views of the bay.

The boat trip to Santa Clara island is a short seasonal ferry-style crossing from the harbour of San Sebastian, in Spain's Basque Country, to the small island that sits in the middle of La Concha Bay. Boats leave from the Muelle at the Puerto de San Sebastian, below the Parte Vieja, and cover the roughly 700 m to the island in about 10 minutes each way. The service is run by Motoras de la Isla and operates as a seasonal harbour boat from June to September.

The activity is a simple boat crossing followed by independent time on the island, so there are no fitness or skill prerequisites beyond the ability to board a small boat and walk uphill on the island's path. Children are generally welcome, but families should confirm any age or lifejacket rules at the pier. The island has a lighthouse path, a small beach and views back across the bay toward Mount Igueldo and Mount Urgull. Services on the island are limited, so visitors bring swimwear, a towel, sun protection and water.

Fares are modest. A secondary source lists about EUR 4 (USD 4.60) return, or about EUR 6.50 (USD 7.48) return with a glass-bottom bay tour, while another guide lists trips from EUR 7 (USD 8.05). Because published prices differ, the fare should be confirmed at the pier. Operator certifications are not published online, but the boats are licensed passenger vessels operating from the municipal harbour, and visitors may ask the crew about capacity and safety equipment.

Safety relies on the crew's boarding instructions, life jackets on board and a fixed return schedule. Visitors should note the time of the last return boat before leaving the boat, as there is no overnight accommodation on the island and missing the last crossing would leave a visitor stranded until the next day. Rough sea, high wind or swell can suspend crossings. The Spanish emergency number 112 applies in any incident.

The best period is July and August, when boats run most often and the beach is at its most pleasant, although June and September offer fewer crowds. Conditions to avoid are stormy weather and strong swell, when crossings may be cancelled. The harbour is a short walk from the Parte Vieja, so the trip fits easily into a half-day itinerary combining the island with the old town.
