Description: Mt. Arlington stands sentinel on the western side of the southern end of the Berkshire Valley.
Mount Arlington is over 600' above the Berkshire Valley, but summertime views are very limited. The only views to be had are partial views from the various clear-cuts on the mountain's slopes.
Mt. Arlington does not have any official trails to the top, but there are a number of ATV trails and even a dirt road criss-crossing the mountain. The trails are steep, but footing is good everywhere and cliffs appear to be absent.
There is an official parking area for Mt. Arlington trails on Gordon Road. The sign at the parking lot says Berkshire Valley WMA.
There is another access point for Mount Arlington across from Mettle Road. One could easily park on Mettle Lane and then climb Arlington's steep east peak.
