There's a surprisingly beautiful place in Austria - Green Lake. From August to April - it's a green park, in spring the water level in the lake rises sharply due to snow melt and glaciers in the mountains, so deep waters flood this picturesque area every year by 4-5 meters. Sometimes the water level reaches 8 meters, but visibility in transparent water remains up to 30 meters or more. It's at this moment that you need to be there to see with your own eyes the crystal clear fresh water of the lake and a fabulously beautiful underwater park. It's amazing to see comfortable benches, flower beds, bridges and tired paths underwater...
