The drive beyond the house lures you down to the Black Loch, where a broad grass walk leads round among trees, rhododendrons and azaleas. Between the loch and the Policy Field are planted a variety of exotic rowans and maples noted for their autumn colours, many of them raised from wild seed collected in Oregon and Japan. This is part of the garden where, on a quiet day, you may see rooks, red squirrels, swans, ducks or even a stately heron standing at the loch-side.
