The 410 acre park is mainly open parkland which offers a wide range of amenities including, a lake with a wildlife, gardens, a boating area, sports pitches, and children's playgrounds. The headquarters of the Zoological Society of London and London Zoo are both located on the northern side of the park. There are several public gardens including Queen Mary's Gardens in the Inner Circle, which features the Open Air Theatre; the formal Italian Gardens and the informal English Gardens in the south-east corner of the park; and the gardens of St John's Lodge. Nearby is the domed London Central Mosque, better known as Regent's Park mosque.

The Regent's Park was used as a hunting ground by Henry Vlll as he considered it to be an invigorating ride from Whitehall Palace. By 1811 London was growing rapidly and Marleybone Park presented a better opportunity for the crown as development rather than for farming. At that time the new Prince Regent, later King George lV, wanted a new summer palace in north London set in exclusive grounds and John Nash, a government architect, produced a scheme that was bold enough to appeal to the Prince.  The area was renamed The Regent's Park and designed as a huge circle with a lake, a canal and the new royal residence. To pay for it, Nash planned 56 villas in the park and a series of grand Regency terraces around it.

Regents Park is very accessible by public transport including Underground stations at Regents Park (Bakerloo Line) and Baker Street (Bakerloo, Jubilee, Hammersmith & City, Metropolitan and Circle Lines.  There are also a number of buses stop around the park.
