Enjoy some of the most attractive landscape in Portumna Forest park while walking the Bonaveen Looped Trail.The Bonaveen Walking Trail is the longest loop through a variety of trees and open lakeshore. It covers the western side of the park and includes the Bonaveen Point section by the lake. It is on single track which is narrow and twisty in places. The long section around the lakeshore is some of the most attractive landscape in the park with great views out over the expanse of Lough Derg. This trail is open to bad weather at times and can be quite exposed.
