    Nice for a 30min guided boat trip on this big lake in a cave. The deepest part of the cave is 10m and the highest point 12m above the water (if I remember correctly :). The cave is of course a bit chilly, so great escape for a hot day. The guide explains the history of the cave in English, German and French.

    A must see visit in the area. This lake is the biggest underground lake in europe. You visit through a guided tour on a large stable boat. Leaving every 20min or so. Usually the guides speak french english german and italian. Always the same temperature winter and summer 15°C. So even though it is a welcome refreshing in the summer think about a jumper or jacket. The cave is lighted up on the rocks as well as under water. Very pretty and calming sight. The accoustics of the cave being excepyional. Every 2 weeks there is a concert usually Saturday night around 1830 check on the web. Must be booked a while in advance.

    It's a fun half an hour activity, especially nice on a hot day. Don't forget to bring something to wear, though, it's 15 degrees down there.

    The lake itself is wonderful, really breathtaking scenery, well lit, a very pleasant half an hour trip. The guides themselves however are nothing to sing and dance about. Despite being perfectly capable of speaking 'up to 7 languages' as advertised on their website, our boatman decided he could only be bothered to cater for the French and German speakers there, leaving us with a laminated sheet to read with, which, to be frankly honest, is very uninformative. As apposed to any actual geological or historical explanation of anything in the cave we were simply told information like "This rock looks like King Kong" (which by the way it doesn't.) The cafe attached is actually surprisingly good value, about 3.50 for coffees which is fairly standard over here. All in all, I'd go for the experience, it's a lovely atmosphere and very pretty but if you're looking for an informative tour, I'd give it a miss. 5/5 Aesthetics 1/5 Tour
