This place seems pretty much under the radar, no mention of it on this site or zootierlist. it's mainly a farm park but among other exotics are Virginia opossum and brushtailed possum. Chew Valley Animal Park | Hands On Family Run Zoo
Have you visited it Ned ? I went one day last year and it was very much just a petting zoo (farm park). They had Tanukis. Coati's , Meerkats, Capybara's, Camel and a couple of other exhibits. The Opossum must be new as they didn't have them before (July 2018) but the place is very small and there really isn't a lot to see there. It was about £9 to visit last year and personally I felt it was on the expensive side. The cafe was also pretty ordinary and expensive for what you get.
Thanks for the information @Zooreviewsuk. I haven't been there yet but as it's only half hour or so away from where I live I thought I might check it out. There are photos on their facebook page of opossum and possum from August 2018 so maybe you just missed them. I might combine it with some birding at Chew Valley lake.
