Walking tours
A good way of seeing London is on foot. There are many different walking tours, however one of the most prestigious companies is London Walks. Their guides include Donald Rumbelow, who is "internationally recognised as the leading authority on Jack the Ripper" and Britain's most distinguished crime historian. Boasting walks such as 'Old Westminster by gaslight' and 'Jack the Ripper haunts', there are morning, afternoon and evening tours.
Price: A London Walk costs £5 - or £4 for senior citizens, full-time students, and Discount Walkabout Card holders.
