Don't want to venture too far from London to find a countryside walk? This is when the Dollis Valley Greenwalk makes an entry. This decently long walk through Barnet and Finchley is that good surprise as it takes you through what is left of former countryside fields in the Capital city.

When the sun makes an appearance, we all want to venture outside. But where to go in London to have a pleasant stroll without melting? Well, a walk around Welsh Harp, also known as the Brent Reservoir, comes as a nice surprise. Not so popular (except if you live locally), the Brent Reservoir offers shade and fresh air. It’s a perfect place for a nice day out with friends and family.

The Wealdstone Brook is one of the lost rivers of Middlesex. It's a short urban walk, one of my 'lost landscapes' routes around the Harrow area. Ironically, there is no trace of the river left in Wealdstone itself, where it has all been culverted. However, it meanders very prettily through Woodcock Park in Kenton, surrounded by grassy banks and willow trees. This is the best bit! There are further glimpses of it along the route of this walk.

This is a short urban walk exploring the 'lost landscapes of Middlesex'. I was recently introduced to a secret park which I never knew about, and realised this must be the summit of the original Sudbury Hill before it was swallowed up under the tide of suburban housing. The walk visits Elm Park and also takes you past the Harrow School sports fields. It starts and finishes near Harrow School, Harrow-on-the-Hill.

This is a short urban walk exploring another of the 'lost landscapes of Middlesex'. The Yeading Brook rises at Headstone Manor and can be tracked all the way to Ruislip Gardens. This walk starts and finishes in West Harrow, and follows the most attractive section of the river through two pretty linear parks : The Yeading Brook Open Space and Streamside Recreation Ground.

This is the first section of a 12 mile walking route which follows the River Pinn from Pinner to Uxbridge. Of all Middlesex's 'lost rivers' the River Pinn is perhaps the most visible.

The good thing about London is that you do not need to go far to track down some exceptionally decent walks. Take Horsenden Hill for instance: who would have thought that you could walk through meadows, a farm, a forest and along a Canal, all within a London postcode and accessible by tube? And you can! A walk through Horsenden Hill will definitely make you forget you are in the city.

This beautiful walk takes you from the outskirts of Watford into the depths of the countryside to see a host of wild flowers.
