The best time to go to Dundreggan depends on your priorities, but generally, the late spring (May to June) and early autumn (September to October) offer the most pleasant conditions.May and June provide longer daylight hours and generally milder weather, making them ideal for exploring the outdoors. The Caledonian Forest, which Dundreggan is home to, will be coming alive with new growth, and wildlife is often more active. This period is excellent for those interested in guided walks focusing on rewilding efforts or spotting native species.September and October bring the stunning colours of autumn to the Highlands. The weather can be a bit more unpredictable, but the landscape is particularly beautiful with the changing leaves. This season is great for photographers or visitors who appreciate a dramatic, rugged scenery, and it's also a good time for those who prefer fewer crowds than the peak summer months.While July and August offer the warmest temperatures, they can also be the busiest, and midges (small biting insects) are more prevalent.
