Take a bicycle ride down the exquisitely named Bolderwood Arboretum Ornamental Drive. Journeying south from Bolderwood car park, past the deer sanctuary and 2 1/2 miles later reaching the Knightwood Oak, the largest oak in the New Forest. Just before you reach the busy A35. If you cross here you are at the start of Rhinefield Ornamental Drive which leads to the Rhinefield House Hotel & Spa and eventually Brockenhurst.
