Hilbre Islands Local Nature Reserve

'The Islands are cut off from the mainland by the tide for up to 5 hours out of every 12 hours. When planning your journey you must find out the time of high water and allow sufficient time to complete your visit to the islands and your return journey to West Kirby safely. It is possible to visit the islands over high water, in which case allow for a stay of at least 5 hours whilst the tide is in, or alternatively, you can walk there and back over one low water period.'
