Camden Lock is a great place to have lunch or simply sit by the water, drink in hand (of course) and aimlessly watch the canal barges float by. You can also take trips along the Regent's Canal when you visit the markets.
There's no place like Camden...
You'll always find something that catches your eye... Street performers are commonly seen on Camden high street and are an amusing highlight to add to your day trip. They also make great snap shots too!
