Summiting all of the Wainwrights is a popular form of peak bagging in the Lake District, along with the Birketts. Because both lists are based on historical books, unlike, for example, the Munros, their constituents remain fixed, regardless of revisions to height or other metrics. In this regard, they are similar to the Scottish lowlands, Donalds. There are 214 Wainwrights, of which 209 are also classed as one of the 541 Birketts. Wainwrights cover a wide range of heights, from major mountains such as the highest Wainwright, Scafell Pike at , to Castle Crag, the smallest Wainwright at . Wainwright did not state any rules about what should be included in his guides, choosing instead to note his walks according to his favour and their relevance in the landscape, never himself considering the summiting of all of them to be an important accomplishment for others.
