On a wonderful summer day when I was at Aegna island searching for caches, one local resident drove towards me with a golf-car and started invastigating me right away if I had seen a moose already. I told that I had not, yet. While especially emphasizing the last word. The lady saw my frightened face from where it could be easily read that I was thinking how do the moose even get here. Then, she jovially started to explain that they come through the water from Kräsuli side, because the water is low enough there. This is how the cache found its name. The cache itself is away from the sea and it is guarded by a spruce. You can see Kräsuli very well from the seashore and the lowest part between two islands is not far away. You should definitely write into your post if you have seen a moose in Aegna.
At the same day, but few hours later, our paths crossed with the same lady. She told she would like to see another moose on the island, because first time it happened her mouth fell open down to her knees. She was a positive, jolly, and a nice lady. Apparently I did not have the opportunity to see the moose.
I suggest you to take the costal path there, best when walking or by a bike. If you are coming from the harbour then you should set your directions towards Karnap beach.
