Yesterday I came back from the road trip I went on with friends. One of the places we visited was Allikukivi cave. It is located in southwestern Estonia, in Pärnu county. It is carved by a freshwater spring and is 36 meters long in total. The largest room is 3 meters high and about 5 meters wide.
The cave is totally dark and no natural lights reach far. Sadly my external flashlight decided to die and I didn't find the batteries I thought I took with me. I took some shots when others cast a light in the cave with phones. This resulted in very high ISO photos put at least you can see something.
This door leads inside the cave.
Also a cool shot with a group, this is inside the largest room.
