Borrowdale is a valley and civil parish in the English Lake District in the Borough of Allerdale in Cumbria, England. It has a population of 438. Borrowdale lies within the historic county boundaries of Cumberland, and is sometimes referred to as Cumberland Borrowdale in order to distinguish it from another Borrowdale in the historic county of Westmorland.
The valley is a very popular tourist location, with hotels, guesthouses, holiday cottages, bed and breakfasts, youth hostels and campsites, catering for the lowland visitor as well as the hill-walker who can choose from a very wide range of popular mountains, including all the above-mentioned fells as well as England's highest, Scafell Pike.
The valley lends its name to the Borrowdale Volcanic Group, a geological development from the Ordovician period. This rock makes up most of the mountains at the head of Borrowdale, including Scafell Pike and Great Gable.
