Watford.

Watford sits just northwest of London in Hertfordshire, close enough for an easy day trip yet with its own distinct pull, from Cassiobury Park's old canal paths to a high street that keeps things lively after dark. Coffee lovers are especially well served, with cafes scattered across town for a slow morning or a quick pick-me-up. When it's time to settle in, choose among hotels, and round out the visit at one of the local restaurants.
