Aira force and Gowbarrow park are around 155km away from Manchester United, you can take the train to the penrith station then there is a bus from the station to the destination. It is near Ullswater with a parking facility and etc. Aira force is an 18th century design landscape once owned by the dukes of norfolk, now owned by the National trust. The main force falls 70 feet from below a stone. You can borrow the boots so you can walk along the water. I took the 45 minutes trail because time is limited, i follow a 3 days 2 night tour from rabbies. If you took Gowbarrow fell trail that is around 3 hour walk at beautiful landscape with fencing to prevent the animal coming out, you will be award a beautiful view.
