Here's a thing - I started FC3 again on the hardest level but this time have ignored missions. When at Citra's temple I wondered if it was possible to get inside the walls when the mission wasn't active. I found a way using a car to jump up from and clamber in, but once inside it's impossible to get out! Unfortunately the game saved and whenever I restart I'm inside the place, which means I have to start a new game. Oh shi.....ver me timbers!
