Londoners will tell you that it's very tough to get a good view of the London skyline. Parliament Hill is one of the wonderful exceptions to this rule. You'll already be feeling good because you'll be on Hampstead Heath, one of the most remarkable green spaces in London. Make the gentle climb up Parliament Hill, with its surprisingly great view of the city - it's easy to pick out a few iconic buildings like the Gherkin, then you can amuse yourself for hours trying to discern the differences among all the rest. This is one of my favorite spots in London to relax with a picnic and the Sunday paper. Kite-flyers also flock here!
