Opalsøen
A deep emerald lake in an old quarry on Hammeren, ringed by cliffs, and a popular cliff-diving spot in summer.
Opal Lake is a small lake that has filled an abandoned granite quarry on the Hammeren peninsula. Its milky green “opal” water is ringed by sheer rock walls. In summer young people often dive and swim from the cliffs, but the water is deep and cold, so jumping is at your own risk. A lakeside trail links Hammer Lake and Hammershus. Admission is free. It's about a 20-minute walk from the Hammershus visitor centre.
