Thames River Ferry

Board opposite the London Eye. There are different ferry companies, but they all basically cover the four main stops: Big Ben, London Eye, Tower Bridge, and Greenwich. You can buy a one-way ticket or a round-trip ticket. If you buy a 24-hour ticket, you can hop on and off at any time within 24 hours from the time of purchase. Take the boat to enjoy the sun and the scenery along the river. After getting off at Greenwich, walk south along the road, pass through the large park, and check in at the Observatory. Definitely worth a ride~
