I went with a National Trust group but individuals, couples etc. can just book a tour of the brewery. Fascinating history although only reopened by the ‘black sheep’ of the Theakston family in 1992. Very good bistro/cafe and bar as well as the ‘Sheepy Shop’ where their beers and other souvenir products are sold. Possible to book a combo tour and 1-2 or 3 course meal. Two courses were more than adequate for me. After the tour we were given a beer card with 3 vouchers for a 1/3 pint beer each or all 3 for a pint bottle to take home if you’re driving! It looked as if it were possible just to go for a meal without a tour. Several families there including some gurgling and only occasionally crying babies.
Lots of other places nearby. I especially like Thorpe Perrow arboretum which also has a mammal centre starring Meerkats and Wallabies as well as a Bird of Prey centre. Owls fly at 11.30 and other raptors at 1.30 and 3.30. They also have a small cafe. Jervaulx Abbey, a privately owned ruin with cafe and shop is 6 miles from Masham. Could go on but won’t.
