Alfoxton Park has become a country hotel, which the owners have kept in the style of the original house, although it seems to be the wrong way round, facing a steep hill and turning its back on the lovely view across country to the Bristol Channel. We ask directions to Dorothy's Glen, a ravine with a waterfall and rushing stream that Coleridge described in the poem This Lime Tree Bower My Prison: "The roaring dell, o'erwooded, narrow, deep/And only speckled by the midday sun." The friends often walked from here to Kilve on the coast, following Holford Stream. They must have had the agility and stamina of mountain goats. The glen is so steep that I fear a wrong step will have me tumbling uncontrollably to the rocks below. I sit down for safety and find myself in a dense white drift of aromatic wild garlic.
