Cruising up the Bay we found that there are too many places to explore so we chose a few we had heard about and never visited when we lived here BK (Before Kids). St mary's is a well protected area with excellent holding and good breezes to keep you cool. The College maintains a dock that visiting Yachtsman can tie their dinghy's to for free and explore the grounds and the historic St Mary's site.
Entering from the Bay you will find the water deep (23' at it's lowest) and the river wide. Numerous mansions line the water with long flowing green lawns. We found it to be a place numerous boats come foro the weekend though Horseshoe bay is so huge that there is no crowding here.
St Mary's itself is quiet safe and very relaxing. We had many a good nights sleep here without worries of anchor dragging or the sounds of civilization.
