On the outskirts of Tallinn, the park at Kadriorg Palace is a beautiful and peaceful spot. It was a glorious day when we visited, in the middle of summer, and yet we saw only a very small number of visitors wandering through the grounds. I loved all the colourful flowers, and it was a wonderful place for a gentle walk. I was surprised that it seems to be so overlooked.
There's also a museum in one of the palace buildings, but it was closed when we visited.
