The River Quaggy flows northward through Chinbrook and forms part of the borough and postal boundaries there.

[1] The name Chinbrook is derived from "Chin Brook" which was an alternative name for the Quaggy River at the turn of the twentieth century.

Marvels Lane is a smaller road passing north to south; southward it joins Dunkery Road, which goes eastward also towards Mottingham; northward Marvels Lane joins Burnt Ash Hill which goes through the northern part of Grove Park towards Lee.

The 284 bus begins its route here at nearby Grove Park Cemetery and travels along Marvels Lane and Chinbrook Road.

There is a building on the northeast corner of the main crossroads containing many retirement flats, this was built in 1999 where Grove Park Tavern previously stood.

Chinbrook Estate, to the southeast of the crossroads is several small roads, has two high tower blocks plus many smaller terrace houses and flats and two community centres.

Some of the many footpaths crossing the park form part of The Green Chain Walk[8][9] and Capital Ring.

In the early 2000s however the concrete channel with its fences and hedges was demolished and river was remodeled to give a natural, meandering appearance with a small flood plain; this was to encourage wild plants and animals back to the area and to be more pleasant and attractive for the public.

There are several foot bridges with wooden hand rails over the river, that replaced the concrete ones with iron fences.

The footpath that leaves the southeast corner of Chinbrook Meadows is part of the Green Chain Walk passes the allotments then Grove Park Cemetery before entering Elmstead.
