For the most pleasant weather and a full range of outdoor activities, the best time to visit Ardgartan is between May and September.During these months, you'll experience longer daylight hours and generally milder temperatures, making it ideal for exploring the Argyll Forest Park, walking along Loch Long, or enjoying a boat trip. The summer months, July and August, are particularly popular for families due to school holidays and the warmest weather, though this also means more visitors.For couples looking for a quieter experience with beautiful scenery, late spring (May-June) or early autumn (September) can be perfect. The midges, while present in summer, are less prevalent during these shoulder seasons, and the landscape is often stunning with spring blooms or autumn colours.
