Guide only. Tide times are official Hilbre Island predictions from the UK Hydrographic Office (falling back to Open-Meteo model estimates if the feed is unavailable); the indicative route is based on Friends of Hilbre crossing guidance, not a surveyed or ranger-approved line. The 3-hour departure and 3.5-hour return margins are app planning rules, not an RNLI-approved schedule. Wirral Council crossing guidance describes the route and walking time. Always follow the official information at Dee Lane and your own judgement of the conditions.
