Drymen lies to the west of the Campsie Fells and enjoys views to Dumgoyne in the east and to Loch Lomond in the west. The Queen Elizabeth Forest reaches down to the village edge, and the whole area is part of the Loch Lomond and the Trossachs National Park (the first National Park in Scotland). The population at the 2011 census was 820.
It is often used as an overnight stop for hikers on the West Highland Way, and forms the western end of the Rob Roy Way. There are a couple of pubs and a walkers' shop. The Clachan pub claims to be the oldest pub in Scotland and to have a connection with the family of Rob Roy.
Despite the growth in the numbers of villagers commuting to Glasgow to work, there remains an agricultural tradition in the area. Every year, in early summer, an agricultural show is held in the fields around the Endrick Water.
