Unpredictable, alas, but most impressive when it happens:
A very enjoyable long-distance walk in Tasmania (Australia) is the Overland
Track - from Cradle Mountain to Lake St Clair. A comfortable five-day hike.
There's a hut at the northern end of the Lake, and one time that I spent the
night there, there was an electrical storm. High vertical cliffs on both
sides of the valley, and the thunder echoed back and forth, taking about 40
seconds to die away completely. Fantastic!
No recording alas. Well before there were recorders small and light enough
to carry along with camping gear and five days food.
