The largest viewing area is wheelchair friendly. The other two are accessed by steps.
I've been a few times with my kids when heading up to Bolton/chorley area to visit relatives.
Also, an OK cafe for a hotdog/burger/coffee.
Can't remember admission cost, usually about £5 for all of us if memory serves.
There is a bus service to but I have no idea of the details.
