Bartender Spring is located at around 2,175 feet on the Ridge Trail. This is the last water source if you are going up the Ridge Trail and the next water will not be until you reach Old Rag Shelter at the ends of the Saddle Trail and the Old Rag Fire Road. While it is unusual, Bartender Spring sometimes dries up in the summer. All water obtained outdoors on the mountain should be filtered, boiled or treated. The spring is 3 tenths of a mile before and 200 feet in elevtion below the last good camping spot on your way up the Ridge Trail. This camping spot is just before the No Camping Sign (see picture below) which is located at about 2,400 feet on the Ridge Trail. In order to protect its fragile micro habitats, there is no camping on the high rocky parts of Old Rag. The no-camping-zone is marked by the sign on the Ridge Trail and a similar sign just above the Byrds Nest shelter on the Saddle trail.
Remember to practice Leave No Trace ethics and to follow the park's regulations (both organization's websites have links above right) .
NOTE: THE LARGE WIDOW MAKER(LEANING TREE) FINALLY FELL AND IS NOW CUT INTO THREE LARGE PIECES THAT REST ALONG THE TRAIL BLOCKING WHAT WAS ONCE THE SOCIAL TRAIL TO THIS LAST CAMPING SPOT.
