Walking Tides
For most of the year, Tresco and Bryher are separated by a narrow channel of clear Atlantic water. But when the lowest spring tides arrive, the water retreats to reveal a temporary trail of sandbars and shallows between the two islands.
Walking tides are a wonderfully unique Scillonian occasion: part adventure, part gathering, and a chance to cross a stretch of seabed usually hidden beneath the water.
With sand underfoot and the sea drawn back, you can wander between the islands, enjoy a taste of life across the channel, and return with suitably wet feet and a story to tell.
Below are the dates, times and predicted tide heights when the crossing should be possible.
The route begins at Flood Hatch beach on Tresco. Set off roughly in the direction of Samson, follow the sandbars towards the middle of the channel, then turn for Church Quay on Bryher. Wet ankles are to be expected, and wet knees are not unheard of. Much beyond that, however, and it may be time to check your navigation.
A few words from the Harbourmaster
The sea may have retreated, but Mother Nature is still in charge. Our Harbourmaster has the advice below before you venture forth...
- Wear suitable footwear
- Check the tide times, weather forecast and local conditions before setting out, as wind and atmospheric pressure can alter the height and timing of the tide. If in doubt, check with the Island Office
- Never attempt the crossing in fog or poor visibility
- Always tell someone you are going
- Never begin walking back more than 30 minutes after low water
It is possible to cross to Bryher and return on foot, but should Bryher tempt you to linger, never try to outrun the returning tide. Far better to stay a while, explore the island, and take the boat back to Tresco instead – check the day’s times with Tresco Boat Services.
