I am from there and the person above almost has it fight with exception of distances. Ribchester and brockholes are about a 50 minute drive there is far better and closer things!
Malham Cove 2 minutes away little walk, lots of nice country tea rooms and pubs.
Skipton 25 minutes away, lovely market town, excellent castle, canal trips, tearooms.
Slightly further is Bolton abbey which is close to the steam train.
Clitheroe castle is well small, but Clitheroe has some lovely shops and eateries.
Gisburn itself has a deli, lovely walks, the park itself has a lovely restaurant and a small park.
Holden cough nurseries is the nicest garden centre I've ever been too great Xmas stuff and is 10 minutes away.
Gisburn is a countryside location so if you don't like walking it isn't for you!
