It could be difficult to get a clearance. I once had to fly there in a Puma HC1 (which was always short of fuel). Having called up for a VFR entry clearance the controller held us outside for 45 minutes. Just as I was about to declare a fuel emergency he called us in and then tried to climb us and give us vectors for an ILS. I then had to break the bad news - the Puma didn't have ILS.
