Isle of May National Nature Reserve best time to visit and seasonal birds
January–February: the island is closed to ordinary visitors. Winter Turnstones and Purple Sandpipers are identified in NatureScot's site citation, but they are not targets for a routine landing trip in these months. Use the closed season to choose a spring sailing and mainland base. A daylight harbour walk in Anstruther is a separate coastal outing; it should not be presented as a substitute island viewpoint. March–April: seabirds typically return to their breeding ground, with ordinary visitor landings beginning in April. NatureScot describes Guillemots returning to the ledges in March and Puffins coming ashore in early April. During the boat's assigned island visit, use Green Face and Greengates viewpoints for the cliffs and the marked grassland paths for Puffins. The sailing determines the time of day; a long settled watch matters more than a theoretical dawn start. May–June: typically choose these months for the broad breeding-seabird spectacle. Guillemots and Razorbills occupy the west cliffs, Kittiwakes can be watched around South Horn, and Shags use Lady's Bed. Puffins move between the sea and their burrows. Start at the nearest authorised viewpoint after the landing briefing, then allow a substantial watch before moving. Never cross grassland to get closer to a burrow entrance. July–August: chick feeding and departures usually change the colony through the summer. Watch fish-carrying Puffins from marked paths and compare cliff activity at Green Face with the south-end views. The main auk season fades during this period, with timing varying between years. Use the latest operator report when choosing a late-season sailing; a midday landing can still be rewarding if you stay quietly at a productive view. September–October: September can typically offer migrant birds during the remaining visitor season, with less emphasis on the summer auk colony. Work sheltered path edges and authorised viewpoints during the time ashore, listening as well as looking. Ordinary visitor access ends by the start of October. The reserve's 1 October 2026 blog confirms that year's public season had closed; autumn seal activity takes place within a different access context. November–December: the island remains closed to ordinary visitors. NatureScot identifies autumn seal nurseries and winter shore birds as important parts of the reserve's ecology, but the island is not a year-round walk-in destination. Choose the next breeding-season trip by its published operator timetable and use mainland coastal routes for winter birdwatching. Avoid planning around an assumed special landing or an unannounced extension of the season.
Isle of May National Nature Reserve opening times, entry and facilities
Reserve admission is free, with the boat journey paid separately. The 2026 ordinary visitor season has finished; NatureScot's reserve blog confirms closure on 1 October. Landing access is normally April–September. Select an actual published sailing rather than relying on general season dates for a particular day. Mainland parking needs to cover the entire trip and check-in. Fife Council's tariff checked on 18 October 2026 gives East Basin a two-hour maximum during 1 April–30 September, charging 80p for one hour or £1 for two hours, 08:00–18:00 daily. That time limit is unsuitable for a normal landing excursion. Choose a lawful longer-stay alternative and read its own signs. The mainland departure postcode is not an island road destination.
Isle of May National Nature Reserve trails, hides and visit length
There are no hides to connect on a conventional circuit. The map supplied with a ferry booking identifies island paths, viewpoints and landmarks, starting from the harbour and visitor-centre area. Green Face and Greengates provide cliff-colony views, South Horn gives another perspective on Kittiwakes, and Lady's Bed is a named Shag-watching area. Choose a few sustained stops rather than treating every historic structure as an essential detour. Two-hour plan ashore: after the staff briefing, orientate yourself at the visitor-centre information area and choose one safe cliff viewpoint. Give the birds an extended watch, comparing ledges with birds approaching from the sea. Follow the signed path back through suitable Puffin-watching ground and make a second settled stop where it leaves room for others. Begin returning to the harbour well before the instructed boarding time. This editorial plan assumes your operator actually allocates that much shore time. Full-day plan: the travel, check-in, crossing and island visit together form the day. Prepare on the mainland, then use the landing allocation for the west-cliff and southern viewpoints that fit comfortably. A standard visitor sailing does not provide an unrestricted full day ashore. Keep the rest of the day flexible for harbour birdwatching or a coastal walk after returning, rather than attaching a time-critical onward activity. Stay on the mapped paths to protect burrows and ground nests, and do not cross to Rona, the research area. Remain well back from unfenced cliff edges and supervise children closely. Watch a Puffin from a stationary position beside the route; if your presence blocks its return to the burrow, give more space. Carry optics ready for a sea watch as well as the land colony, keeping equipment secure when moving between the boat and shore.

Isle of May National Nature Reserve accessibility and step-free routes
Discuss the complete journey with the boat operator before booking if mobility is a concern. NatureScot describes partial disabled access on May Princess, while Anstruther Pleasure Cruises' own current terms state that the vessel is unsuitable for wheelchairs under marine-safety regulations. The operator says it tries to accommodate portable equipment and folding buggies, and requires passengers to manage gangways and steps. Its booking-specific assessment takes priority over a broad accessibility description. The visitor centre itself has no steps and contains a fully accessible toilet. Other island shelters differ: South Horn has a flight of steps with a handrail, and the bath house also has entrance steps. Reaching an accessible building does not remove the need to negotiate the crossing and island paths. Explain your balance, transfer and equipment requirements to the relevant operator, including whether you can fold an aid or walk a gangway with assistance. An open RIB has a different seating and boarding experience from the larger passenger vessel. Choose the trip only after establishing that the whole route suits you, including the return in changing sea conditions.
Isle of May National Nature Reserve visitor facilities
The island visitor centre offers interpretation, an information area and a sheltered wildlife view through large windows. Staff update the outdoor information with island news and sightings. Bring food, water and warm waterproof layers for the shore visit rather than depending on a meal outlet. Take all litter back to the mainland. Keep a waterproof cover for optics and secure loose clothing during boat travel. The mainland harbour provides separate facilities before boarding and after the return.
Isle of May National Nature Reserve dog rules
May Princess' operator prohibits dogs on the boat and island, explicitly including assistance dogs under its landing-licence conditions. Anyone who relies on an assistance dog should contact the operator before planning the journey and establish an appropriate alternative arrangement. Do not assume another island or mainland reserve's dog policy applies here.
Isle of May National Nature Reserve public transport and getting there
Anstruther Harbour is the main Fife departure point. Stagecoach's 2026 Anstruther travel guidance identifies service 95 through East Neuk communities and X61 linking the town with Kirkcaldy and St Andrews. Plan the bus against the actual sailing check-in, leaving a margin for delays and the walk to Middle Pier. The harbour is an interchange with the boat, not the reserve itself. For rail arrivals, use a suitable Fife station and its onward bus or prebooked taxi connection; check the complete journey through the transport operators rather than treating the crossing as the only fixed part of the day. Stay locally before an early departure if the public-transport margin would otherwise be tight. Other licensed trip options depart from North Berwick and Dunbar, as listed by NatureScot. Those are separate mainland journeys and should be booked with the named operator, not reached using an Anstruther ticket. For every departure port, reserve return-travel flexibility because a boat itinerary occupies a substantial part of the day.
