Weather permitting we will visit RHS Wisley : https://www.rhs.org.uk/gardens/wisley/introducing-wisley/looking-good-now. Fingers crossed the weather is as good as it was last year when the sun shone all day, we were able to eat outside, the gardens were awash with crocuses and other spring flowers and as you can see from the photo we enjoyed the living willow sculptures by the lake.
If it rains, or is very cold, we will visit Guildford Cathedral instead when there will be a free organ recital as part of their programme of coffee concerts : https://www.guildford-cathedral.org/events/coffee-concerts
