Bonchurch Landslip is managed by the National Trust and has to be towards the top of your must-visit list of things to see whilst visiting the Island. It is literally an old LandSlide and the resulting scenery resembles something from a long lost world and has an almost tropical rainforest feel to it. The Devil's Chimney is a narrow gap in the rock cliff through which have been hewn steps. You will not believe your eyes and visiting this for the first time is definitely memorable. Visiting it for the 100th time is something you will probably end up doing.
The Smuggler's Haven tea room at the top of the walk has plenty of food and drink with great views over the sea to enjoy.
The Landslip is believed to have existed for thousands of years, but its present terrain derives largely from major landslide events in 1810 and 1818. An 1811 account by Thomas Webster described the scene:
I was surprised at the scene of devastation, which seemed to have been occasioned by some convulsion of nature. A considerable portion of the cliff had fallen down, strewing the whole of the ground between it and the sea with its ruins ; huge masses of solid rock started up amidst heaps of smaller fragments, whilst immense quantities of loose marl, mixed with stones, and even the soil above with the wheat still growing on it, filled up the spaces between, and formed hills of rubbish which are scarcely accessible. Nothing had resisted the force of the falling rocks. Trees were levelled with the ground ; and many lay half buried in the ruins. The streams were choked up, and pools of water were formed in many places. Whatever road or path formerly existed through this place had been effaced ; and with some difficulty I passed over this avalanche which extended many hundred yards.
The Bonchurch Landslip was developed as a picturesque woodland walk in Victorian times, with natural features including the Devil's Chimney, the Chink, and the Wishing Seat (a.k.a. Wishing Stone, a large moss-covered rock by the path).
