A trip to Speeton Sands

We spend the morning at Speeton Sands. There has been a gap in the weather and it's very pleasant, long sunny spells, with just a light breeze. It is almost low tide, and as we climb down the cliff onto the beach, we watch Gannets and Sandwich Terns diving for fish not far from the shore. Squadrons of Guillemots and Razorbills move to and from Bempton Cliffs. From the hillside a Chiffchaff sings.
 We search for fossils on the clay at the base of the cliffs, and for a long while we find nothing. Then we reach an area of slate grey clay and find a cluster of belemnites, some of them the smallest I've seen. Later we find another good patch and a large fragment of an ammonite.
 We walk until the base of the chalk cliffs and then turn round. A young seal is on the edge of the rising tide, trying not to get splashed by the waves, oblivious to us. It looks healthy, so we leave it alone.
 By the caravan park, we watch a pair of wagtails courting, the female not too welcoming to the male's courtship dance.

Spring at Speeton Sands

North of the chalk cliffs of the Flamborough headland lays Filey Bay, an arc of golden sands backed by clay cliffs. Reighton and Speeton sands make the southern end of this bay. At low tide the beach is very wide and the views impressive, with the backdrop of the cliffs on one side and Filey bay in the distance. Other than the usual beach entertainment, there are other things to explore: the eroding cliffs are covered on scrub and wildflowers, and the clay they are made of is the only site in the U.K. with a marine lower Cretaceous exposure. Walking along the bottom of the cliffs it is relatively easy to collect fossil Belemnites, Ammonites and bivalve shells. There is no need of equipment as the clay is quite soft. Occasionally the tides uncover fresh clay under the sand, and then it is a good opportunity for good finds. Every visit will be different because of the speed of erosion.
 A walk on the hillside illustrates how quickly plants and animals colonise the mudlides. Little primroses, coltsfoot and violets were growing on clay that evidently had settled not long ago.
 Today we spot the first swallows of the year flying south and the first Chiffchaffs and Willow warblers sing from the blackthorn and gorse.

These wellington boots left behind stuck to the mud serve as a warning to visitors. There are frequent mudslides and flows and the mud can be caked outside, but soft and sticky inside.

Location map
Access through the village of Speeton is not recommended due to recent mudslides. Go to Reighton Sands Holiday Village from Reighton leaving the entrance to your right. There is a car park and a relatively safe way down to the beach.
