Walking on the Sea Bed

Friday was a big tide, in fact a very big tide.  The tidal range of 11.8 metres resulted in a significant movement of water.  As it approached low tide we were able to go walking on the sea bed.
We met at La Rocque Harbour, the south east corner of the Island.  Unfortunately the blue skies and sunshine from the west coast were replaced by an approaching fog.  It was rolling in from the sea and obscuring all the physical features.
Icho Tower was about 1.5 miles away, the benefits of GPS ensuring that we had this information, but at times we could see less than a hundred metres.  Heading so far offshore in the fog requires confidence in your navigation abilities.  So for the first time in nearly 60 years of living in Jersey, when walking I had to walk on a compass bearing to ensure that we found our planned destination, Icho Tower.

Our departure point. La Rocque Harbour, with the fog starting to roll in from the sea.

Leaving La Rocque, at this moment our feet were still relatively dry! We were already walking on a compass bearing by this time.

As we headed across the beach there were a number of water filled gullies. They became increasingly deep, so the optimism of dry feet from wearing wellington boots, was changed into flooded boots and wet socks.

Icho Tower appeared out of the mist, when we were less than 100 metres away, according to the GPS.  The tower was built in 1811, part of the coastal defenses designed to protect the Island from possible French invasion.  It is easily seen whilst driving along the coastal road at Le Hocq but visiting on foot is restricted to the larger spring tides.  We decided to have lunch in the hope that the water retreated from the deeper gullies before we headed east towards Seymour Tower.

Icho Tower gradually appeared from the mist. We were within a 100 metres before we could see anything for definite.

As we had lunch on the rocks at Icho Tower the fog was gradually thinning and visibility improving.

As we walked between Icho Tower and Seymour Tower the visibility improved and the sun came out.

Approaching Seymour Tower after the sun finally came out.

Seymour Tower is unique among the defensive towers, which are found around the coast of Jersey, in that it is square.  It was built in 1782, a direct consequence of the 1781 invasion, which resulted in the Battle of Jersey.  Today it is a unique place to stay overnight, with bookings available through Jersey Heritage.  It lies at the heart of the RAMSAR site, situated off the south east corner of Jersey.

Sitting on the platform in front of Seymour Tower, the views to the south were amazing. Such a privilege to live on such a special Island.

Looking back towards Jersey from the steps on Seymour Tower, the coast is just visible through the hazy conditions. At this point we were only about half way towards the low tide mark. The sea really does retreat over the horizon.

This screen shot from the ViewRanger App shows our route. Friday’s route is shown in red whilst the black route is our walk on the last large spring tide.

The screen shot above, really does indicate that we were walking on the sea bed.  As the tide drops, particularly on the larger spring tides, a unique coastal environment is exposed.  A great place to explore but somewhere, which needs accurate planning to avoid being cut off by the tide.
