Worth the effort – on foot
Good free viewing both sides of the circuit. There is always good action to be seen on the Dunlop Curves as the cars slow (or not as the case may be) before “cresting” the Dunlop Bridge (they go under it). There are also some good views on the airfield/museum side looking down from just before the Dunlop Bridge back down to the start line.
As a point of interest you can’t see the track from on or by the side of the Dunlop Bridge – they’ve covered it in!
