Rutland Water Bathing Beach

 
This life-guarded swimming oasis boasts a sandy beach and warm clear water. It stands as a beacon of best practice, a shining example that could be replicated country wide if only local authorities and water companies could face up to and overcome their current prejudice towards outdoor swimmers. A heartening example of what can be achieved to advance the interests and quality of life for all.
