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.

Autumn wildlife in Borrowdale

Throughout the woodlands of Borrowdale, you can find both Red and Roe Deer grazing in the underbrush. You may hear the bellow of the red deer as their rutting season spans through to November.

There are also plenty of bird species to watch and listen to including peregrine falcon, barn owl, tawny owl and little owl. Great wood and Cockshot wood, away from busy roads, are both great spots to stop and sit quietly while looking up at the canopy. There you will find a moment of peace while listening to the many sounds of nature. A perfect place for a bit of forest bathing.

You might also spot one of the otters that visit our woodland streams and gullies. Please give them a wide birth as they are private creatures and we are hoping to ensure their numbers grow.

Another timid species to be found in Borrowdale is our thriving population of red squirrels which can be a little easier to spot as the leaves start to come down. If you are hoping to catch a glimpse of one your best bet is to arrive early in the morning before the crowds scare them high up into the trees.

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.
