I visited this WHS in May 2010. It is quite remote, close to the Arctic Circle and still cold although there was the midnight sun when I went there. However, you'll be rewarded for your perseverance if you visit this place. The snow-capped mountains and sea form an idyllic background to the numerous rock carvings at Alta. The visitor centre is very well organised with valuable information and a much needed cup of hot chocolate after visiting the site.
