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.
The house's last incarnation was as Cowal Resource Centre, which provided daycare for adults. Staff and clients regenerated the woodland area and when the centre was demolished the woodland was taken on by Bullwood Nature Trail community group as a resource for adults of varying abilities to gain experience of woodland maintenance and development. It is currently being looked after by the Grow Food, Grow Dunoon project team, who are reviving the community food growing aspects of the site.
