You can see as far as the snowdonia mountain range and the great orme at Llandudno to the west which is approximately 68 miles to the highest peaks of snowdonia as the crow flies as it shows in the pictures I've uploaded on a very very clear day with zero smog,

And there's quite a lot to see the other way looking east towards winter hill, some lovely views up their and its a perfect location on a sunny day for walking or picnicking or bike riding

you can also see parts of the lake district mountain range aswell if the weather is clear enough if you look north towards Blackpool Tower
