Best Hiking Trails Near London 2026

London is a flat city built on the Thames floodplain but it is surrounded by a green belt of protected countryside and the chalk ridges of the North and South Downs provide genuine hill walking within an hour by train. The Thames Path national trail also runs through central London providing 184 miles of riverside walking in both directions. Here are the best hiking options near London for 2026.

Box Hill and the North Downs Way

Box Hill in Surrey, 35 kilometres south of central London (50 minutes by train from London Waterloo to Box Hill and Westhumble station), is the most popular day hiking destination from the capital. The chalk and greensand hill above the River Mole, made famous as the picnic destination in Jane Austen's Emma and as the finish of Stage 14 in the 2012 London Olympics road race, rises 224 metres above the Mole Valley with views across the Surrey Hills to the South Downs. The National Trust estate at Box Hill includes the zigzag road up the escarpment, the viewpoint café at the summit, and a network of walking trails through the chalk grassland and ancient box woodland that gives the hill its name. The North Downs Way national trail passes through Box Hill and can be walked east toward Dorking or west toward Guildford in either direction for longer linear walks.

South Downs Way: Lewes to Alfriston

The South Downs Way national trail, running 160 kilometres from Winchester to Eastbourne along the chalk ridge of the South Downs, offers the finest open downland walking within reach of London. The section between Lewes (55 minutes from London Bridge) and Alfriston via Firle Beacon (217m) is among the most spectacular: the open chalk ridge with 360-degree views of the Sussex Weald to the north and the English Channel to the south, the sweeping dry valley landscapes, and the absence of trees on the exposed ridge combine to create a walking landscape entirely different from the enclosed woodland of the North Downs. The section is approximately 15km one-way and can be returned by bus from Alfriston to Lewes or walked as a loop via the Weald villages below the escarpment.

Chiltern Hills: Ridgeway Trail and Wendover Woods

The Chiltern Hills northwest of London, accessible from London Marylebone to Great Missenden or Wendover (50-60 minutes), provide beech woodland walking that is characteristic of this chalk escarpment region. The Ridgeway national trail, Britain's oldest road, follows the Chiltern escarpment and provides elevated walking with views of the Thames Valley and the Vale of Aylesbury. The Wendover Woods forest park near Wendover provides a network of trail through mature beech and pine forest with the Hale Wood and Boddington Hill circuit providing a 5-10km forest walk. Autumn (October-November) is the finest season for Chiltern walking when the beech forest is at the height of its copper-and-gold colour change.

Practical Guide to Hiking Near London

All major hiking destinations from London are accessible by National Rail train from central London termini (Waterloo, Victoria, London Bridge, Marylebone). The National Trust and Natural England maintain detailed trail maps for all sites. The Ordnance Survey app (OS Maps) is the standard navigation tool for UK walking and provides the 1:25,000 Explorer series maps covering all areas described. The green belt protection around London ensures that the countryside immediately beyond the suburban edge remains largely undeveloped.
