Purbeck, Dorset, England
The chalk stacks at Handfast Point are as geologically connected to the Isle of Wight's Needles as they are spectacular. CoastMetric tells you exactly when to come.
About Old Harry Rocks
CoastMetric is a real-time conditions app built for coastal visitors. It pulls together live weather, tides, wind speed, air quality and path conditions into a single Visit Score — helping you plan the perfect visit to Old Harry Rocks and the Purbeck cliffs.
Old Harry Rocks and Handfast Point are exposed chalk sea stacks and headland on the open Dorset coast. Cliff edges collapse regularly. Data shown is gathered from third-party sources and may not reflect current on-the-ground conditions.

Out-and-back along the cliff edge from Knoll Beach car park to the Old Harry sea stacks. Flat and well-maintained path with panoramic Poole Bay views.
Return via the chalk ridge of Ballard Down for wider Purbeck views. Steeper ascent from the beach — good in fine conditions, slippery after rain.
