We did Ae last week for the first time and enjoyed it, we've done Dalbeattie three times previously and had great fun.
We've also done Kirroughtree and Glentress a couple of times and Mabie just the once.
Mabie is possibly the least favorite ( IMHO ), but overall ….
They're all damn good fun !!
Do which ever you fancy and then do the other on the next trip :)
