The only fee you have to pay to visit Lands End is for the parking fee but visiting the Lands End and going through Lands End is free on charge.
The cost to park in the car park at Lands End is £6 which is around $7.00 in USA dollars.
The parking fee and pass is good for 7 days of parking so you can visit Lands End more than once with that one time parking fee and then renew it again 7 days later if you want to park in the car park again.
You could park somewhere else further away and then walk to Lands End and avoid the parking charges.
However the fee would be well worth it to park in the car park to avoid having to walk very far.
