Texas is blessed with some of the nations most interesting "show" caves and thousands of "wild" caves throughout the state. Because of the varying geographical regions and features of Texas, you could literally tour the entire state by jumping from cave to cave.
Known as Waiahuakua, this is the second longest sea cave in the world, stretching 1,155ft. It is known as the Sacred Water Cave and as the Double Door cave – as it has both an entrance and an exit. Kayak tours run through the cave to allow visitors a close-up view of the caverns huge length. A fissure in the roof of the volcanic rock allows water to gush into the amazing cavern.
My favourite picture view of the river Nidd in Knaresborough. My grandparents lived here, and it was my second home since I kept my ponies at Manse Farm in Knaresborough from 1975-1979 when we emigrated.
