We saw about 6 people. A younger couple with a dog and two women with four dogs between them, also another couple getting into their car at a point where the forestry track crossed a small road.
We headed up to what was shown as a lake on the map, but it's not really a lake any more.
However, I don't recommend trying to walk across that area as it's very likely just a floating mat of vegetation with water underneath!
There was a tiny bit of water visible at one end.
This was the view as we sat and ate our cheese and biscuits.
The whole walk was only about 2.5 miles, but it was nice to get out and we avoided the crowded touristy areas.
