Green Chain Walk

The Green Chain Walk page covers a 29.42 km route with 373 m of total elevation gain, and it is graded easy. That makes it a long day walk or a relaxed multi-day outing rather than a steep or highly technical hike.

Most hikers should allow roughly 6.5 to 9 hours of moving time for the 29.42 km Green Chain Walk, depending on pace and stops. The route is rated easy, but the full distance across southeast London is long enough that many walkers split it into shorter sections.

Yes. Transport for London describes the Green Chain as part of the Walk London network and notes that these routes are designed so people can walk as little or as far as they want by using sections. That fits the Green Chain well, especially across southeast London where public transport access is built into the route.

The Green Chain is a signposted network across southeast London that links woods, parks, and major green spaces. Official descriptions highlight places including the Thames Barrier and Crystal Palace, while the Royal Borough of Greenwich notes routes rising from the Thames through Lesnes Abbey and Woolwich Common, converging at Shooters Hill, then continuing toward Eltham, Grove Park, and Crystal Palace Park.

Yes. Transport for London states that the Walk London routes, including the Green Chain, are specifically designed to be easily accessible by public transport. That makes it practical to start or finish different sections without needing a car, especially around Thames-side access points, Eltham, Grove Park, and Crystal Palace.

Dogs are generally allowed on much of the Green Chain because it passes through public parks and open spaces where dogs are welcome, but local park rules still apply. In Royal Greenwich, dogs are permitted in parks with controls in place, so leads or extra care may be needed in signed areas, around wildlife habitats, sports pitches, or other restricted spaces.
