Even the most die-hard Soho-ite, might not have heard of this little gem. Tucked away just behind the junction of Charing Cross Road and Shaftesbury Avenue, its a little oasis of calm in the hub of the city. Its also got its own slice of history - originally a WWII bombsite and later a car park, it was then taken over by the Covent Garden Open Spaces Association. Granted its not as pretty as one or two of the other parks in London weve included (there are no manicured lawns and neatly tended flowerbeds here), but though it's a bit rough and ready, it's also a lovely little place to hang out. Best of all, while Soho Square and Golden Square are jam-packed with people weekend and weekday, Phoenix Garden is almost always pretty quiet, and can even be hired out completely for your own private summer party.

Chelsea Physic Garden
Founded in 1673, the Chelsea Physic Garden is the second oldest botanical garden in Britain. It's home to over 5,000 different types of medicinal plants and herbs, many of them rare and endangered species. Theyve also got the largest fruiting olive tree and the worlds most northerly grapefruit tree. After pottering around the pomegranates, the gingkoes, the mulberries, and the eucalyptus, the place to make for is the award-winning Tangerine Dream Cafe where they serve the most amazing afternoon teas in the most fragrant of surroundings. It's not hard to see why it's one of Anya Hindmarch's favourites.

St Johns Lodge in Regents Park
Lovely as Regents Park is, hundreds of bikes, children and dogs dont always make for the most peaceful of strolls or relaxing of picnics. Which is why well generally be found sneaking off to the inner circle to the St Johns Lodge garden. The lodge itself belongs to the Sultan of Brunei and the half-open gate implies it might be a private garden - except it's not, it's totally open to the public and absolutely beautiful. You can head down the pergola walk, to a large circular garden and the most perfectly manicured lawns. With a tinkling fountain and pond and lots of hidden pockets of green, both of which are bathed in sunshine and under shaded trees, its the perfect place for a wonderful lazy summer's afternoon. Frankly, it's so lovely, were not entirely sure why were sharing it...
Address: Regents Park, NW1 4NR
Kyoto Gardens Holland Park
Originally the grounds of Jacobean mansion Holland House, Holland Park is one of our favourite parks in London for a long, lazy picnic. The ruins of Holland House are now the backdrop for the wonderful open-air Holland Park theatre and half of the park's 22 acres are now semi-wild woodland - both are really quite beautiful. For a more secluded picnic, the place to head for is the zen-like Kyoto Gardens. Built in the park, the gardens were laid out by specialists flown in from Japan and feature ponds filled with carp, a waterfall and hundreds of Japanese trees.
Address: Ilchester Place, W8 6LU
