The area was beautiful and peaceful, save for one English idiot (me) who disturbed the tranquility by splashing in the water for an hour. But the water was lovely, and with the lake being around half a mile long (the photo shows the width), it meant there was no endless turning round, as with a pool.
It wasn't possible to check the temperature of the water, but judging by the fact that I could only last an hour before the shivering set in, I think it was anywhere between 10-12 degrees. It did make a lovely change to a pool swim, I must confess.
Tonight I am being taken back (again by Neil). I'm hoping to endure an hour and 15 minutes of the cold but tranquil water.
