The water of Lake Louise has an emerald colour which comes from rock flour carried into the lake by melt-water from the glaciers that overlook the lake.
The view from above can be reached by a nice, not too strenuous hike. Do mind the weather though, on the way back we really got soaked in a heavy thunderstorm.
Very close to home I witnessed and photographed the blue hour at the Reitdiep Haven. This is a very recent part of the city of Groningen, situated in the North-West. It’s well-known because of the bright-coloured houses.
