Located 15 miles southwest of East Grinstead (and within east reach of Arundel, Brighton, and Lewes), this spectacular country estate is the region's most luxurious stay, set within 92 acres of Sussex countryside and including a small vineyard, woodland walk, kitchen garden, and rockery. Still, it's what inside the hotel that counts. The beautifully appointed bedrooms, suites, and lakeside lodges are individually designed to combine heritage features with modern comfort, and there are wide-ranging dining options in the three excellent restaurants—including the Michelin-starred Ben Wilkinson at The Pass—along with the billiard bar and garden terrace. Perhaps the highlight, however, is the state-of-the-art spa, with an indoor pool and a natural outdoor swimming lake, as well as a scented sauna and salt steam room. Breakfast is served in the elegant Camellia, or you can eat in the spa restaurant Botanica, which has many vegetarian and vegan options. South Lodge is also an excellent family retreat, with extras for young children including a tent and books in the room, activity trails through the gardens (with prizes), and designated swimming times.
