S'Albufera de Mallorca is the largest wetland in the Balearics and one of the most important bird sites in the western Mediterranean. Around 230 species have been recorded here, and during the spring and autumn migrations the numbers swell dramatically. Resident breeding birds include purple heron, little bittern, black-winged stilt, and Audouin's gull — a species found almost exclusively in the Mediterranean. Ospreys fish the open water with some regularity.
The reserve covers about 1,700 hectares and is crossed by a network of paths and hides. Entry is free but you need to collect a permit from the reception centre, which is on the Ma-12 road between Puerto de Alcudia and Ca'n Picafort — you can see the sign from the main road. Bikes are allowed on the paths, and cycling through the reserve in the early morning is particularly good for birds. The paths are flat and mostly surfaced, accessible without specialist equipment.
Spring migration peaks in April and May, autumn in September and October. Summer is quieter for birds but good for dragonflies and other insects. The reserve is open year-round; early morning visits in any season tend to be more rewarding than midday ones when birds are less active.
