Anne's Beach is the kind of place that wins you over for what it is rather than what the brochures promise. It is a small free park on the ocean side of Islamorada, at mile marker 73.5 on Lower Matecumbe Key, and its charm is the mangrove boardwalk and the gentle shallow water rather than a wide sweep of sand. If you are driving the Keys and want a real, unfussy stop with the children, a picnic and a paddle, this is one of the best free pull offs on the whole highway.
The setting is the draw. A long boardwalk threads through the mangroves and coastal forest, linking the two parking lots and passing a string of covered pavilions with picnic tables, so you can claim a shaded spot, lay out lunch and step down to the water whenever you like. The water itself is warm and very shallow, the kind of calm flats where small children can wade and hunt for little fish and crabs in safety, which is exactly why families return to it. It feels natural and local rather than built up or commercial.
Be honest about the limits before you go. This is not a swimming beach in the deep sense, as the flats stay shallow a long way out and there is grass and soft mud in places, so water shoes help and you set your sights on a wade rather than a long swim. There are no shops, rentals or food on site, just restrooms and the pavilions, so bring your own water, food and shade. Seaweed can gather along the calm shoreline through the warm months, which is natural, so the dry season is cleanest.

The calm shallow flats make a gentle launch for a kayak or paddleboard you bring yourself, with no on site rental, so plan to carry your own gear or hire it elsewhere in Islamorada.

Anne's Beach sits on the ocean side of the Overseas Highway at mile marker 73.5, on the southern end of Lower Matecumbe Key in Islamorada, in the Upper Keys. There are two small roadside parking lots, one at each end of the boardwalk, and they fill on busy weekends and holidays, so arrive earlier for a space and take care turning in and out on the highway. It is an easy, well signed stop on the drive between the mainland and the Lower Keys.
Pack as if there is nothing on site, because there is not, so bring your own water, food for the picnic, and shade, though the mangroves and pavilions give some natural cover. Water shoes help over the grass and soft mud in the shallows, and reef safe sunscreen and bug spray are both worth having near the mangroves. Keep a close watch on children in the shallow flats as there is no reliable lifeguard, and treat the calm and clarity as typical rather than guaranteed.

It can, like all the ocean side beaches in the Keys, with sargassum drifting in mainly through the warm months, and because the water is so shallow and calm the weed can linger along the shoreline. This is natural and beyond anyone's control. The dry winter season tends to be the cleanest, and the mangrove setting and picnic pavilions are a draw whatever the shoreline is doing on the day.
