When is the best time to visit Loch Ness?

The best time to visit Loch Ness is from May through September. However, this is peak tourist season, especially during school summer holidays in July and August, which can make for some uncomfortably crowded experiences. Although the weather will be cooler, you can avoid the biggest crowds by visiting in April or late September/October instead. If visiting outside of peak season, check that attractions and sites are open.
