Not sure where the Red Squirrels are supposed to be but I wonder if the picnic area, on the left as you drive into the car park and hidden from view, might be the best place in hindsight as people are likely to feed them there.
A wander around the conifer woodland looking for the Squirrels turned up a variety of birds including Goldcrest and Coal Tits and many others. Curlew was heard nearby on the adjacent moors and along the edge of the reservoir I had Snipe, Lapwing and Common Sandpiper.
Definitely worth a look if you are in the area.
