The best time to visit Thetford is during the late spring and summer months, from May to September, when the weather is most pleasant for outdoor activities.During these months, you'll experience warmer temperatures and longer daylight hours, which are ideal for exploring Thetford Forest, the largest lowland pine forest in Britain. This allows for comfortable enjoyment of activities like walking, cycling on dedicated trails, or visiting High Lodge, the forest's main activity hub with adventure play areas and Go Ape.Families will find this period particularly suitable, as the pleasant weather makes outdoor excursions with children more enjoyable.
