Can You Scatter Ashes on a Miami Beach or in Biscayne Bay?

It is one of the first questions families ask, and it is a reasonable one. When someone loved a particular beach, or spent years on the water in Biscayne Bay, returning them to that exact place is the natural thought. A gathering on the sand also sounds simpler than arranging a boat.

The answer is not a straightforward yes or no. It depends on precisely where you are standing, who manages that stretch of land or water, and whether the ashes are going onto sand or into water. Those distinctions matter more than most families expect, and they are the reason many end up choosing an offshore ceremony instead.

The three-mile rule does not apply here

The federal requirement that cremated remains be released at least three nautical miles from shore comes from the Marine Protection, Research, and Sanctuaries Act, and it governs ocean waters. It does not extend to bays, rivers, or lakes. The EPA states this plainly: scattering cremated remains in lakes, rivers, or other inland waters is not subject to federal regulation under that Act, though states may have their own requirements, and states may authorize scattering in inland waters including bays under state law or the Clean Water Act.

The reason has to do with where the measurement starts. The EPA describes the three-mile boundary as running from the ordinary low water mark, or from a closing line drawn on nautical charts across the openings of bays and rivers. Water inside that closing line is not ocean water for these purposes, which is why the offshore rule does not reach into the bay.

So Biscayne Bay is not covered by the rule that governs an offshore scattering. This surprises many families, and it is worth stating clearly, since it is a point on which published guidance is often inconsistent.

Florida, for its part, does not impose a statewide ban on scattering in inland waters. There is no state law that makes it broadly illegal.

If that were the whole picture, the bay would be an easy answer. It is not, because the question of who manages the water turns out to matter far more than federal or state law.

Biscayne National Park covers much of the bay

The southern portion of Biscayne Bay lies within Biscayne National Park, and the National Park Service has its own rules that apply regardless of what federal or state environmental law permits.

Scattering cremated remains inside the park requires a Special Park Use Permit. Applications go to the park’s Special Park Uses Coordinator, are reviewed over a minimum of fifteen business days, and must be signed by the Superintendent. The approved permit has to be in your possession at the time of the ceremony.

The condition that matters most is this: cremated remains cannot be placed or dispersed within 100 yards of a body of water, a road or trail, or within developed areas. For a family hoping to release ashes into the bay itself, that requirement rules it out. The park also notes that EPA and Clean Water Act rules apply in addition to the permit, not instead of it.

Because of the distance requirement, scattering is not permitted at Convoy Point, which is the only part of the park reachable without a boat.

Not all of Biscayne Bay falls inside the park; the northern reaches closer to downtown Miami and the causeways lie outside its boundary, where park rules do not apply. If you have a specific location in mind, it is worth confirming with the park whether it sits inside the boundary before assuming either way.

Beaches are governed locally, not federally

Florida sets no single statewide rule for scattering on beaches. Instead, whoever manages that particular stretch of sand sets the policy, and policies differ.

Counties and municipalities set their own ordinances, and these vary from one jurisdiction to the next along the same coastline. A rule that applies on one beach may not apply half a mile away. State parks and county parks generally require permission from the managing agency, and some set minimum distances from the water’s edge. There is no single figure that applies across Florida, which is precisely the difficulty: the only reliable answer comes from the authority that manages the specific beach you have in mind.

There is also a distinction worth understanding. Scattering on sand above the tide line is not the same act, legally, as releasing remains into ocean water. The first is a question of local ordinance and property management. The second is where federal ocean rules begin to apply. Families often assume a beach ceremony is a middle path between the two. It is really a third category with its own set of authorities to ask.

The practical consequence is that a beach scattering requires you to identify the managing authority for that exact location and ask them directly. That is doable. It is simply slower and less certain than most families expect when they start planning.

The part the rules do not cover

Even where a shoreline scattering is permitted, the conditions attached to it are worth reading closely before you commit.

Inside Biscayne National Park, for example, the permit does not give your family exclusive use of the site. The park states directly that access must remain open to the public, that the ceremony cannot interfere with normal visitor activity, and that it will neither exclude other visitors nor allow you to. Audio devices and music may not be used in a way that disturbs other people. Nothing may be left behind afterward, including an urn, a photograph, a plaque, or flowers, and the release of birds or butterflies is prohibited. The park also makes clear that it does not commit to treating the location as sacred or as a burial ground, and that park operations continue without regard to the presence of cremated remains.

Those terms are reasonable ones for a national park to set. They are simply not what most families picture when they imagine a quiet ceremony at a place that mattered to someone.

Conditions on the day are the other consideration. The EPA acknowledges that surface scattering is not always appropriate depending on the wind, which is why it also permits the use of a fully decomposable container. On open water a captain can choose the moment and the position; from a fixed point on a shoreline, there is far less room to adjust.

Why most families go offshore

Ocean scattering has a clearer set of rules, and they are the same everywhere along the coast. No advance permit is required. The release must happen at least three nautical miles from shore, materials must be readily biodegradable, and the EPA must be notified within thirty days afterward. There is no local authority to identify and no jurisdiction to research.

It is also considerably more private. Three miles out there is no shoreline audience, no schedule but your own, and the ceremony belongs entirely to your family.

The practical requirement is a boat capable of reaching that distance safely, with someone aboard who knows the rules and handles the reporting. That is the service we provide, and it is why a great many families who began by asking about a beach end up on the water instead.
