Here's a superb way to kickstart your summer in London: by soaking up the sunshine on the River Thames, as you float past the city's loveliest landmarks. With City Cruises, it's just a couple of clicks away — and right now you can nab tickets for less.

Book and travel on any sightseeing cruise between now and 30 June, and you'll get 20% off. Choose between flexi and timed tickets, or indulge in a 24-hour Hop-On Hop-Off River Pass, with which you can climb aboard and disembark at any of City Cruises' four piers (all of which are handily located near major tourist attractions like the Tower of London, Palace of Westminster, London Eye, and Old Royal Naval College) as many times as you like. 
 
Whichever you opt for, you'll learn plenty of fascinating London trivia along the way, with live commentary in English and multi-lingual commentary delivered via City Cruises' app. Plus, there are activity books to keep the kids happy and plenty of refreshments for sale in the cafe-bar.
