Mile Markers 28 & 29 — The three Torch Keys are at mile marker 28 and 29 on the Overseas Highway. There are three keys — Little, Middle and Big Torch. They were probably given their base name, “Torch,” because of the native torchwood tree, Amyris elemifera. The islands’ most likely claim to fame was as a relatively frequent fishing destination for President Harry S. Truman. Little Torch Key is the most densely populated of the three islands and it’s also home to a couple of commercial ventures, including a restaurant and a resort. The famous Little Palm Island Resort & Spa has its land base on Little Torch.
