[Countrywide] Mirror lakes: where do you get the best mountain reflections, and in which seasons is the “glass water” most likely?

Early mornings are non-negotiable for mirror lakes, and places like Lovatnet or smaller mountain tarns in Jotunheimen have given me perfect glass when the wind is still half asleep. Late summer and early autumn seem to behave best, when nights are cool and the air hasn’t started its daily tantrum yet. From what I’ve seen, sheltered lakes with steep sides beat big open ones every time, and you usually don’t need fancy gear, just patience and an alarm clock you don’t hate. Anyone had consistent luck with winter reflections, or is that mostly a social media myth?

One of the most reliable mirror-lake moments I’ve had was at a small lake just off the road near Sognefjellet in early September. I got there around 7 a.m., and the water was dead calm — mountains perfectly doubled, clouds barely moving. High-altitude lakes work well because the air is still overnight, but once the sun hits, wind usually follows. Access was easy: park, walk a couple of minutes to the shore, no scrambling. I didn’t even bother with a filter, just shot straight into the reflection while it lasted. By 9 a.m. it was gone, so timing really is everything. Did you consider approaching this from the Lom side instead of coming up from the fjord?
