Kotelní jezírko is a small pond tucked away in a peaceful forest setting. It's a popular stopping point for people walking in the area.
It's a beautiful and quiet place, ideal for a short break during a hike. You can sit on a bench, enjoy nature, and it's on the way to other sights like the ruins of Kyšperk Castle.
The main thing to be aware of is that the pond is often dry or muddy, especially in the summer, so it's not suitable for swimming. The facilities like the benches and the wooden pier are a bit worn down but are still usable for a rest.
The pond is on the trail between the top of the Komáří vížka funicular and the town of Krupka. The walk from Krupka can be a moderately demanding climb along a stony forest path.
