Nestled behind the colourful Tigh na Cladach eco-house development on the outskirts of Dunoon, Bullwood nature trail is a wooded hillside that was once the extensive garden grounds of a mansion house called Alderwood. There are many mature trees and many woodland plants, including hawthorn, primroses, foxgloves, ferns, mosses and fungi. A wildlife pond is a habitat for frogs and more. The site it currently quite overgrown in places with some large patches of invasive plants including Himalayan balsam.
