Planning around Isla de Alegranza starts with understanding that it is not a normal day-trip destination. Landing is restricted within a protected natural area and generally requires prior authorization, and there is no open public access, published opening hours, or regular visitor pattern. Travel would only be by authorized boat during daylight hours when sea conditions allow, with no public transport, scheduled visitor service, parking, road access, or landing infrastructure for general visitors. Authorized stops are generally brief daytime visits only, and normally the island has no other visitors. Do not plan for facilities. There are no toilets, showers, shelters, shade structures, shops, food, drinking water, bins, or cleaning services, and all supplies would need to be carried in and all waste carried out. There is also no lifeguard service and no managed, sheltered, or prepared swimming area. The shore is natural and uneven, with volcanic rock, rough terrain, and very little natural shade. Sun exposure is high, and wind is common. Weather is mild year-round, with warmer and drier conditions from late spring to early autumn, commonly May to October. Even in calm-looking conditions, the surrounding water is open Atlantic sea water with possible swell, currents, and wind. Anyone with authorization should bring sun protection, wind protection, sturdy footwear, sufficient water, food, and a plan for waste removal. There is no assistance on site and no accessible infrastructure, paths, or support for limited mobility, so risks include sun exposure, rough terrain, and changing sea conditions. Check authorization requirements and any protected-area restrictions well in advance and do not attempt to land without it.
