I used to work in Stockley Park Heathrow, which is the largest business park in europe (apparently), home to Activision, Apple, BP, British Gas and some other rather large companies.
Anyhow I used to walk through Stockley Park Golf course, and it gives a great view of Heathrow Air Port and the Surrounding area, must be the highest area for a fair few miles.
