Isn’t this lake too cold? It looks stunning and fresh, but at this height and this time of the year it may be well around 5 degrees. Is swimming in these lakes even allowed? Here in Bulgaria, at the mountain national parks you can easily end up with a pretty solid fine if you even step inside.
Switzerland is surely pretty beautiful and these views are just breathtaking. Your friends must be very happy with their decision to visit you.
I wouldn't try it now :) We will go there again in summer to try. Then it should be bearable :) It is allowed, there is a sign confirming it. Luckily, there are really not that many people coming there, so in summer could be a lot of fun.
Thank you! I think they indeed enjoyed it :)
