We can’t recommend Pure Boats enough. We decided to take a private boat tour to celebrate our daughter’s birthday. There were 12 of us, 6 adults 6 children. It wasn’t much more expensive then the impersonal group tours but so much better value for money. Nothing was too much trouble for Geertjie making the arrangements. They decorated the boat for us , provided cake and selfie props. Our guide was great fun and knowledgeable. We had a great time. Thanks so much.
