The weather is very warm and summery now and the crickets are coming out in full force in the evening. Maybe this is not the best time for sightseeing in the city centre, but it’s a great time to explore any of the lakes surrounding Munich. The water quality is good everywhere (but you need to be a reasonably good swimmer. The lakes are not as well guarded as the pools and lethal accidents happen almost every year). At the Chiemsee (above) you can often see fish jumping.
Have a lovely summer!
