To avoid the list becoming infinitely long and arbitrary, only hills with more than 30 m relative height are included.
Marilyns are peaks in the British Isles with 150 m of relative height; Hewitts are peaks in England, Ireland and Wales over 2000 ft (610 m) elevation, with at least 30 m relative height.
There are 22 Marilyns and 28 Hewitts in the Yorkshire Dales National Park.
Topographically, the boundaries of the Yorkshire Dales trace the flow of streams from the lowest points between it and the neighbouring regions of the Lake District, North Pennines, Forest of Bowland, South Pennines and North York Moors.
Marilyns are given in bold, followed by the hills within their territories, which are delineated in the map.
