Step outside and explore Hampstead Heath, London Zoo and beyond.
Morning: Hampstead Heath and Camden
Glorious Hampstead Heath is the perfect place to spend a morning. Situated on the edge of the heath is Kenwood House, a magnificent neoclassical mansion set in 112 acres of .landscaped parkland. Open to visitors all year round, the house's superb collection of paintings by masters such as Rembrandt and Turner is a real highlight.
Hop on the bus to Archway Tube station and take the Northern Line to vibrant Camden. You could easily spend hours here, browsing the bustling arts and antiques markets, relaxing along the canal and wandering the colourful streets.
Afternoon: London Zoo and Regent's Park
One of the world's oldest zoos, ZSL London Zoo is famous for its conservation work and incredible diversity of animals (758 species can be found here). Highlights include the Tiger Territory enclosure, home to the zoo's two critically-endangered Sumatran tigers, the Gorilla Kingdom and the ever-entertaining penguin beach.
London Zoo is located at the edge of Regent's Park, so while you're there stroll around Queen Mary's Garden and the boating lake. If you are feeling energetic, walk up to the top of Primrose Hill for lovely views across London.
Evening: Open-Air Theatre and Dinner
Regent's Park is also lucky enough to have its own Open-Air Theatre. The season runs over the summer months and group discounts are available. If you visit out of season, try Shakespeare's Globe, which is open for slightly longer (from April to October) - or its new candlelit indoor theatre, Sam Wanamaker's Playhouse, which is open all year.
Finish the day with an al-fresco dinner on the waterside. If you're around Regent's Park, head for chic Rotunda along the canal near King's Cross. Or if you opted for a show at Shakespeare's Globe, walk up the river to Butler's Wharf and take a seat on the terrace at Butler's Wharf Chop House, for an amazing view over Tower Bridge at night (note: terrace tables cannot be reserved).
