Here are a few quick suggestions for cool places to go and things to do when it's too sunny - if there can really be such a thing?
Take a walk by a cool Dales stream or river - you can't go far without coming across one. Paddling optional. Take the plunge with some wild swimming or just pop along to Ingleton Open Air Lido
Go underground - the temperature in caves like Ingleborough, Stump Cross and White Scar tends to be around 9 degrees centrigade, regardless of the weather outside.
The huge thick walls of castles such as Skipton and Bolton Castle were designed to keep out intruders, but they're also pretty effective at shielding visitors from the sun.
Enjoy a walk in the dappled shade in one of our wonderful woodlands such as Hackfall or Skipton Castle Woods.
Climb to the top of a hill in search of cooler air, perhaps one of the lesser known Dales 30 and look around to see if there's anyone around. Chances are you'll be entirely alone.
Enjoy a walk in the shade, maybe exploring the arches of the immense Ribblehead Viaduct, or the inside of the Hoffmann Kiln.
Find a lovely cool piece of limestone pavement (rocks foundation, not by the road!), lie down on your back and gaze up at the endless sky and watch the birds swooping below.
