Our family returns here every time we are in the Keys. We take our own boat out there and tie up to an anchor point (they have a variety of locations). The reef spreads out from the lighthouse and depths range from fairly shallow (4-5ft.) to around 25-30ft. Our kids enjoy snorkeling, and we usually tie up a few floats... More

We rent boats and snorkel to avoid the crowds. Sombrero reef is the nicest in the area, and best in the early AM, before the crowded snorkel boats arrive. And most will moor up right next to you even if every other mooring ball is available. GO EARLY! More
