Go on an off-road safari hike in jeeps and see the most interesting places of Aidu quarry, cross steep ascents, and drive through water.
Reading a map, orientating, looking for paths and passages, crossing obstacles, communicating with a radio transmitter, etc. add even more excitement to the safari. If you are interested, you can drive the jeep on your own.
The guide will surely talk about shale and environmental issues.
To finish off the day, enjoy a hot sauna and stay for a night at the Estonian Mining Museum.
Good to know: be sure to dress in accordance with the weather.
