The large tank (the one on the left) was not so difficult to enter, and the air quality was much better than expected. You need to climb down a two-storey ladder affixed to the tank’s side after climbing through a slightly narrow access hatch. It’s not so difficult to do this but as this article says, BE CAREFUL when climbing up/down old ladders!

We didn’t enter the other large tank on the right. This one is only accessible by descending down the big ladder. Looks terrifying and nerve-wracking, also quite dangerous. If you don’t access that tank the difficulty rating of the site is surely far lower than an 8/10.

A couple of dog walkers around the area. Also, there was a film crew in the tanks when we went. Seems like it can be semi popular on sunny weekends.

I would advise not to go down into the tanks all alone. There is a strong smell of fuel and a respirator mask is preferred.

Last but not least, use an app such as Organic Maps to view routes, tracks and buildings. Google Maps is rubbish outside cities.

Hi Oven,
Assuming you are enter the site by the main entrance, go to your left and follow the path down the hill to your right. You’ll go through trees till you come to a clearing. Those tanks are basically in front of you then, the big hills. Climb up and you’ll find the entrance though a hatch.
Good luck!
