I had a lovely London Waterbus Trip from Little Venice to Camden Market, so I thought I should share the details, in case anyone else is interested. The prices vary, but they are £12 for adults, £9 for students, and £8 for children. It takes about 45 minutes to get from one station to another and the guide told us about what we passed by. The provider we went with is London Waterbus Company, but there are a couple more. So, while booking is recommended, you might be able to get tickets with the first ones that leave the station. Enjoy the pictures!
