Rest and be thankful is the famous stopping spot at the top of Glen Croe.

Glen Croe  is a glen in the heart of the Arrochar Alps surrounded by large and rugged mountains characterised by huge boulders. Glen Croe is located to the North West of Loch Lomond and Loch Long, the latter of which it drains into. At the head of the glen is the pass leading to Glen Kinglas. The A83 road runs the length of the valley, passing the viewpoint known as Rest-and-be-thankful. Glen Croe is situated entirely within the Argyll Forest Park.

The old road through the glen seen in the photograph is part of the Military Road that ran from Dumbarton to Inveraray. This was built in the 1740s under the supervision of Major William Caulfield and a stone inscribed Rest & Be Thankful was erected around 1749, after this section road was completed. From 1949 until 1970 motor racing events, including hill climbs and rally stages took place here.
