To the north and northeast it is bordered by the steep slopes of the Tote Gebirge with the Kammersee, and to the southwest in front of it is the Grundlsee.
From the parking lots in Gössl, at the end of the Grundlsee, two hiking trails about 1600m long lead to the Toplitzsee in the beautiful nature reserve of the Tote Gebirge.
Lake Toplitz has always been a target of conjecture and rumor due to its exceptionally great depth.
After the collapse of the Third Reich, this chapter was enriched by an episode. According to eyewitness accounts of locals, dozens of crates are said to have been sunk in Lake Toplitz during the last days of the war. Since then, it has been repeatedly assumed that these boxes contained the last gold reserves of the Third Reich. Many a treasure hunter who tried his luck in the lake, which is closed to divers, had to pay for this recklessness with his life.
According to the latest findings, Lake Toplitz was the scene of secret underwater experiments with explosives and rockets. During professionally conducted search operations, counterfeit English pound notes, which would have been used to weaken the English economy, were found. Counterfeit stamps, explosives, weapons and other war relics were also recovered, but never gold. Nevertheless, speculation about a gold deposit in Lake Toplitz has never completely ceased.
Speculation that the famous Amber Room was sunk in Lake Toplitz during the last days of the war was fueled when a submarine at great depth took pictures of a box labeled in Russian. What was inside the large box was never known.
Some relics found as well as visual material about the dives are exhibited in the fishermen's hut at Lake Toplitz.
