Sand and Barrel Jellyfish at Carlyon Bay, Cornwall.


Carlyon Bay beach, Cornwall

There is a long beach at Carlyon Bay, St.Austell, Cornwall. 

The photo above was snapped after I had walked to the far end of the sand, so not many people about! Well, none actually! It gets much busier though at the height of the summer season. 

This far end of the beach was once a designated for naturists. I'm not sure if this still applies as the beach has confusing plans for redevelopment - mind you this has been promised / threatened for many years, but actual building work has never commenced.

The other end of the beach (photo below), nearest the car park, is quite popular. There are rocks to explore and so on. Some people are even brave enough to plunge into the water.

You have to be a little aware, if close to the cliffs, as there are rock falls occasionally.

When I walked to the far end of the beach all seemed peaceful, other than a young seagull blowing in the wind.

But then I spotted something in the sea - jellyfish - big ones!

Barrel Jellyfish seen at Carlyon Beach

They are Barrel jellyfish (Rhizostoma pulmo) and are said to be the largest in UK waters. I have read that they can grow as large as a dustbin lid - and are sometimes, therefore, known as dustbin-lid jellyfish.

The jellyfish can sting but this is not normally harmful to us humans.

The jellyfish aren't at Carlyon Bay all of the time! They are most likely to be seen in May or June when the waters start to warm. They can get washed ashore if they swim too near the beach.

There always seems to be something interesting on a long beach. I have seen a very large fin whale washed ashore at Carlyon Bay, which was quite upsetting. 

After walking the length of the beach I retraced my footsteps to the most popular section - and the flags were flying!

As I walked back to the car - up a hill unfortunately - I snapped a final photo looking out to sea.

Kindly note this post was also published a while back. I am not available at the moment.

Many thanks for visiting my blog.
Good wishes ~ Mike.

  We had to make a short visit to Fowey so I snapped a few quick photos as we walked. The first two are views on the way from the Fowey car ...
