The easiest approach to Corlic Hill is from the Old Largs Road running between Greenock and Largs. There are other options but they tend to be spectacularly wet and boggy.
There are many options for parking off the Old Largs Road but please do not park at the entrance to the private road which leads to the hill (N55°55.613' W004°46.211').
Follow this road up past Whitelees Cottage, and the obvious path continues on to the summit. The going can be wet and muddy so walking boots or wellies are recommended.
From the top of the hill you will have views over the Clyde estuary to the north, and the Gryffe Reservoirs to the south. Good views can also be had over Loch Thom to Dunrod Hill.
A few years ago there were plans to build a wind farm up here and on Devol Moor to the east, 23 steel towers 312 feet high were proposed by developers Airtricity, but fortunately permission was refused after a public enquiry.
UPDATE: A new proposal to develop a wind farm on this site was made by 2020 Renewables, a company whose board are made up mostly by ex-Airtricity directors and managers. Sadly this was given the go-ahead so this area will be full of wind turbines soon.
The cache is a 450ml clip-lock box in a green waterproof bag. At the time of placing it contained a guitar pick, a keyring, a couple of badges, a whistle, a bouncy ball, a yo-yo, an eraser, and a glowstick necklace.
