Chelsea Physic Garden
A true classic among London’s gardens, Chelsea Physic Garden is an enchanting oasis just a short walk from the River Thames. Founded in 1673, it’s one of the oldest botanical gardens in London and home to more than 5,000 species of medicinal, edible and herbal shrubberies.
While the garden’s not free to enter, the peaceful atmosphere, historic glasshouse and beautifully curated borders make it well worth a visit away from the hustle and bustle of London. It’s a rare chance to experience centuries of botanical history right in the heart of a high-class area of the city, Chelsea.

Run entirely on donations, it’s one of the area’s few green refuges and a lovely place to pause, especially if you’re exploring North London on foot. Why not come and see one of the best gardens in London for yourselves?

St. Mary’s Secret Garden
Despite its name, St Mary’s Secret Garden is one of East London’s most inspiring green spaces, providing a relaxing retreat in Hackney. This community-led garden offers much more than a peaceful walk, it supports wellbeing, education and skill-building through gardening courses and volunteering opportunities. Visitors can also support the garden by purchasing indoor and outdoor plants, homemade jams and garden supplies.
Explore woodland paths, a tranquil pond, sensory and herb gardens, wildflowers and the much-loved ‘Wish You Well Garden’. The space’s aim focuses on those in need to develop valuable skills and contribute to a greener community.

Phoenix Garden
Built on a former WW2 bomb site by volunteers in 1983 and tucked behind Soho’s lively streets, Phoenix Garden feels like a secret world of its own. This small but beautifully maintained community garden is in the heart of the city, but once you step in, you forget you’re in London. It might be dainty, but it’s a perfect getaway on a summer’s day and for a quiet break during a busy day in the West End.
Run by volunteers and supported by donations, the garden has a no-bikes, no-dogs and no-alcohol policy, keeping it calm and welcoming for all.

Kyoto Garden, Holland Park
One of London’s most tranquil Japanese-style gardens, Kyoto Garden is hidden within Kensington’s Holland Park. Featuring waterfalls, koi carp and carefully sculpted landscaping, it’s especially stunning in spring and autumn.
Originally built as an addition to the park in 1991 to celebrate the upcoming 1992 Japan Festival in London, it’s a popular spot, but still feels peaceful if you visit early in the day. The park was a gift from Kyoto, honouring the friendship between the two countries. It's well worth a proper wander round when you visit, making sure you don’t miss out on some of the park’s hidden beauties.

Postman’s Park
Just moments from St Paul’s Cathedral, Postman’s Park is a small but moving green space steeped in history. It’s best known for the ‘Memorial to Heroic Self Sacrifice’, commemorating ordinary people who lost their lives saving others and might otherwise have been forgotten. The park acquired its name due to its popularity as a lunchtime garden with workers form the nearby old General Post Office.
With shaded seating, seasonal flowers and a reflective atmosphere, it’s a perfect pause during a day of central London sightseeing. Weave through the garden from east to west with its pathway.
