The Cannon Point and Birchville Dam walk is a 90-minute intermediate level trail through the hills north of Upper Hutt. It is 8km long and passes through both private land and Greater Wellington’s Akatarawa Forest. The trail starts from Tulsa Park and zigzags uphill through private land and Akatarawa Forest to the summit, where you’ll find spectacular views over the Hutt Valley. It then continues along old forestry roads to the north and descends to the historic Birchville Dam
