For the best chance of warm and sunny weather, and enjoying the extended daylight hours, the best time to explore Spey Bay and its surroundings is from May to August. This is peak season, however, so it’s a good idea to make reservations for campsites in advance. The nature reserve is a great place to visit year-round. Visit between spring and summer to see butterflies; in winter for ducks and divers, and all year for dolphins.
