There are plenty ways to go along the Thames, from 20 to 50 minutes, giving you an alternative view of the city.
Sailing in London.
It's clear that the best way of experiencing the atmosphere of the city is to walk, but there are also very entertaining alternatives. One of the most attractive is to sail on the River Thames, through the heart of London. From the Greenwich area to the east, as far as Westminster to the west, you can visit various piers where different types of cruises set sail and cross the river. From these boats, you'll see the city in a different way: facades and monuments that you find on the riverbank like the Tower of London, the Parliament or even the bridges surrounding it. Furthermore, it's an activity that you can adjust to your plan of the day since there are many combinations and types of tours, from 20 to 50 minute journeys, to lunches or dinners in the on board restaurant. If you prefer, it's possible to get off somewhere that you feel like talking a walk for a while, and then you are able to catch the next boat later, to continue your voyage.
