Fabulous walk on mostly level ground with a variety of scenery.
Some steps and slopes but manageable for all.
We returned to our car the same way so obviously the walk is twice the distance recorded.
The route can be circular if you return from the beach on the other side of the lake but it is through wooded areas so quite shady.
The beach has no facilities at all so take water and provisions.
This walk can be done in reverse. There is a National Trust car park at Broadhaven Beach. If you do it in reverse, you have a pub and cafe in Bosherston for refreshments before you make your way back to Broadhaven and your car.
