Surrounded by 30 acres of parkland that leads to the coast at Climping, the bucolic setting alone makes a stay at this luxury Sussex hotel feel like a proper reset-and-recharge getaway. But it has several themed retreats too, including one night of mindful stargazing (dates in April, September and October) with Mark Westmoquette, an astrophysicist who teaches yoga and mindfulness. Less about understanding scientific concepts or cosmological theories and more about being at one with the universe, it includes celestial meditation, a group discussion on our place within the world, a dusk Qigong breath work and movement session, and dawn zen yoga. Plus, of course, a three-course dinner, full English breakfast and full use of the spa, including the indoor and outdoor pools. Other current offers include spa and dine, a spoiling overnight special, from Sunday to Thursday, with a two-course dinner.
