As night descends and the ocean recedes star like shapes of luminous green (bio-luminescence) begin to twinkle and sparkle in a few special spots at low tide. See the bio-luminescence and other marine life. Take a guided “moonwalk” across the sea bed near Seymour or Icho tower. Expect to get wet -maybe up to the knees- as you discover and experience the uniqueness of this walk. In just a few hours the sea will return and cover your footprints by up to 40ft of ocean. Note. The amount of bio-luminescence can vary. Due to the huge tide range do not venture into this area unless you have local knowledge, or are with a guide. Reservation essential. Walks are in small groups. Private walks on other dates are possible. Accredited Jersey Heritage Trust Seymour Tower guides. Adventuremark, Green Tourism approved.
