Every PTC hike is given a classification from 1 to 4, according to the table shown below. This is done so that hikers know what to expect in advance and are not unpleasantly surprised by a hike that turns out to be too hard (or too easy!) for their abilities and tastes. Occasionally a hike will appear with a classification such as "1+" or "2/3," indicating either a level of difficulty judged to lie between two classes, or a hike with a short section which is more difficult than the lower class number indicated.
|Class 1:||Easy.||Mostly flat with good footing.|
|Class 2:||Intermediate.||Rolling hills and some rocks on trail.|
|Class 3:||More difficult.||Steep ups and downs, trail rocky but stable.|
|Class 4:||Most difficult.||Very steep ups and downs over rocky area that might be loose. Handholds may be needed.|
