Leave Oxford Street behind, forget Covent Garden and steer clear of Leicester Square. Instead hop onto the Victoria line and head south until you reach the final stop in Brixton.
When you re-emerge into the daylight, turn right out of the station and take the first right along Atlantic Road. After a short walk, you'll see an entrance to Brixton Village on your left.
Brixton Village is a wonderful market bursting with boutiques, bistros, delis, cafes, vintage clothes shops and retro furniture stores.
The building that houses the market used to be known as Granville Market and was almost demolished a few years back. Thanks to the tireless work of a group of local residents and traders, the historic structure was saved and renovated, and recently reopened as Brixton Village.
Take some time to explore the small independent shops, but be sure to pay a visit to Federation Coffee (above) while you're there. For many, this place serves the best coffee in the whole of London. If you're not a fan of coffee, order a cup of tea instead, and enjoy it with one of their mouthwatering cakes.
Once you're done, it's time for a stroll. Take the exit which comes out onto Coldharbour Lane and turn left. Walk (or take a bus) along Coldharbour Lane until you come to Loughborough Junction train station. Turn right into Herne Hill Road and continue along until you come to Finsen Road on your left. Here you'll see an entrance into Ruskin Park.
Relax and enjoy this lovely 36-acre sloping park. Make your way to the top and take a look back across central London. On a fine day you should be able to spot several famous landmarks.
Having explored Ruskin Park, the chances are you'll be needing some liquid sustenance. Well, you're in luck as there's a brilliant boozer in the vicinity. Just leave the park at the same place where you came in, turn back down Herne Hill Road and take the first right into Kemerton Road. There you'll find The Cambria pub.
The Cambria is a welcoming establishment with a stylish interior and pleasant garden area. If you're there late in the day, how about getting a bite to eat too?
