A traditional London double-deck bus usually runs at regular intervals at weekends and during school holidays to provide visitors with a nostalgic 20 minute ride.  This is subject to volunteer crews being available and the buses used being serviceable on the day. 

Phone 01932 837994 on the day to check whether buses will be running.

Fares are £2 adult, £1 child.  Book your seats first at the London Bus Museum shop, which is also open for the sale of souvenirs, books, models etc.
