It's not easy to get a good place as there are hedges close by the track in several sections.
The best place is called the esses at the top of the bank after start, but it gets packed.
The two hairpins are OK, the one at the far north end is quite a walk but less busy.
By the start/finish is an extensive grassy bank with good opportunities but you will want a decent zoom.
It's notorious for delays due to sea fog affecting the top of the course, be prepared for chilly conditions in any month
