Around this time in Amsterdam I start looking for things to do indoors once the weather goes from blue sky to gray sky, and this autumn has brought the Amsterdam Climbing Wall (Klimmuur) to my attention. If you too are in need of using up some energy, but it's raining buckets outside...or even if you've just spent one too many afternoons in the Vondelpark to want to go back, the climbing wall is not yet a very well known place; that being said, it IS a very well-frequented place!
