As another local cruiser told us, this is one of the best places on the St Johns River. Located on the west shore of Lake George, this is a federally managed facility by the National Forest Service. shallow draft boats can even enter the spring and stay overnight. the spring water is crystal clear after coming off the tannic rich waters of the lake. Back up by the spring, local boats anchor on the shallows...reportedly can be very busy on weekends and holidays....a popular party spot. Yesterday there were probably 20 boats in there and as we left a 50' houseboat was headed in. Draft will vary with water levels and it's down now. Apparently you might get in with a 4' draft, but looked more like 2.5 to 3. Entrance is weedy with sandy muddy bottom. We anchored out in the lake and dingied into the spring. We went all the way back to the start of the fee area around the actual spring. if you go on land there is a $5.50 user fee, but if you stay in the water you can walk past the two sets of steps and enter the spring at no charge. take a swim mask and swim in the crystal clear spring. BTW, do not tie off to the vegetation.....$150 fine! also, today we hope to dingy up to Salt Springs on the northwest corner Lake George, reportedly a lovely canoe/kayak trail. we have been there before by land yacht....it's actually a more interesting spring than silver glen with multiple sources and more spring structures to explore. We are at the nearby Georgetown Marina. Jim Quince TWINS
