Many of these hills are important historical, archaeological and nature conservation sites, as well as popular hiking and tourist destinations in the county of Somerset in southern England.
The table is colour-coded based on the classification or "listing" of the hill.
The types that occur in Somerset are Marilyns, HuMPs and TuMPs, listings based on topographical prominence.
Peaks with high prominences tend to be the highest points around and likely to have extraordinary views.
In this context, a "TuMP" is a hill with a prominence of at least 30 but less than 100 metres, and should not be confused with the traditional term appearing in place names 'Tump'.
