The ancient ‘Atlantic oakwoods’ in Borrowdale and Derwent Water are both protected as Sites of Special Scientific Interest (SSSI). Find out which rare plants and animals you can expect to see during your visit, including the best places to spot native red squirrels.

Winter wildlife in Borrowdale

Owls have their breeding season when snow is still falling. If you go for a walk in Great Wood around February half term, you can hear tawny owls hooting to each other in their quest to find a mate; the female calls ‘tu-wit’ and the male replies ‘tu-woo’. 

While there is fresh snow on the ground, look out for the tracks of wild red deer, rabbits and even otters.

Remember to keep your ears open as well as your eyes and enjoy the soundtrack of winter in the mountains with the song of the raven which is much deeper and more musical than the crow.

The Atlantic oakwoods of Borrowdale

Get in amongst this ancient landscape by following the moderate waymarked walk from the Great Wood car park.

The woodlands that cloak the surrounding fells are dominated by oak: these 'Atlantic oakwoods' are the last surviving fragments of an enormous ancient forest that once stretched from western Scotland all the way down the west coast of Britain and Wales.

They receive an incredible 11 feet (3.5m) of rainfall per year and therefore they qualify as temperate rainforest. Look up as you walk and in the crooks of the branches you may see ferns growing – another indicator of rainforest status. As of 22 May 2024, 721 hectares of the Borrowdale rainforest has been declared a new National Nature Reserve as part of the King series.

The woods in this valley are one of the most important habitats in Europe for mosses and liverworts (bryophytes), and lichens – especially 'old forest species'. As a result of their rarity and diversity, all of the Borrowdale rainforest is protected as Sites of Special Scientific Interest (SSSI).

The best places to spot red squirrels in Borrowdale

Red squirrels have inhabited Cumbria for the past 6,000 years. Today, their grey cousins are pushing them close to extinction, but there is a population in the valley that we are fighting hard to protect.

The best time to come for a walk in Borrowdale's woods and see squirrels is in spring or early summer before the leaf canopy hides them from view, or during and after the October half term once the leaves have started to drop.
