On Sunday I needed some exercise, and decided to take a walk in the area of Pitkäjärvi in Espoo. I picked a route that would allow me to visit the Nepperi cave and took my drone just in case I needed to peek from the sky at some point.
Nepperi is reportedly the biggest cave inside Ring III. But I was expecting very little based on descriptions in the net and from my friends. However, this turned out to be a small but interesting cave. The interesting bit was a small passage on top of big rectangular blocks, tight enough to not be able to go through with a helmet on (I think --- I didn't have it with me on the walk anyway). After the squeeze for maybe four or five meters, you enter the upper ledge where there is a bigger and more open cave room, with the horizontal crack opening to the cliff face. By this time your are about three or four meters high up on the cliff.
There was another way in as well, but I didn't try it because the slippery, wet rock right on the side of the cliff didn't look very inviting.
And once again, apparently obviously, we're finding this cave from the excellent retkipaikka.fi and an article by Antti Huttunen. Great work, Antti!
Coordinates: N 60.250153 E 24.729517 (the link goes to Google Maps). Parking: I parked along Haapaniementie at coordinates N 60.249195 E 24.727937 and walked through the woods. At some point you'll come across a fence protecting people from the cliff drop. Go under the cliff, not above.
