Hi Colin,
Best to check the contact information on the main Forum . Give the hotels a ring , if you have,nt already. It is a bit hit and miss at this time of year given the extremely variable weather we are having but don't let that put you off. The Don can really come up trumps ,even this early in the season , as the bigger trout can switch on to the feed but in my opinion I would caution against fishing the very upper beats as , for me, it's still too early for them.
Hope that helps.
Paul.
