Bristol Lost Underground Waterways

I got myself a s i b boat in order to be able to explore some some of those hard to get to places. I thought a good place to start would be Bristol Underground tunnel network of waterways and lost rivers which are now covered up by the city streets. Some of these tunnels used to be access ways to get goods into the town Centre and a rumoured to be be slave Tunnels and also no pirate smuggler tunnels. The main tunnel we're looking at has been explored by some other people in the past but we are hoping to go beyond and the point that a lot of people stop out and explore into the distant reaches beneath Bristol in future videos.
