Here's why it's called Red Strand Beach.
In spite of it being in July, the water was freezing and even our granddaughters wouldn't get in it. But they enjoyed running in the sand and playing on the rocks to the east.
There were lots of shells and jellyfish to play with and avoid.
We had been there in 2015 and this time there was a food truck there.
The web sites referenced in the 2015 post have mostly gone away but don't let that dissuade you from visiting. Take a blanket to spread out and turn the kids loose.
We went more than once during this trip.
