Beautiful lake that you can walk around on a leisurely stroll... quiet paths on one side, a small beach and restaurant on the other... unfortunately, the nearby motorway is sometimes quite loud.

Diatomaceous earth was created by open-cast mining until the mid-20th century. Diatomaceous earth is a whitish substance derived from the shells of diatoms, which are the main component of marine plankton. They range in size from 10 to several hundred micrometers. Diatomaceous earth was used to produce shock-resistant and portable dynamite from nitroglycerin, which explodes when shaken.

We really didn't expect such an idyllic spot behind the rest area. A very, very nice area for a break or dog walk.
