The tidal lagoon was created by a massive dredging project in the 1970s and has since evolved into a dynamic natural ecosystem.
The beach is a designated critical wildlife area for several threatened shorebird species, including the Snowy Plover.
The sandbar separating the lagoon from the Gulf of Mexico is not permanent and shifts position depending on storm surges and seasonal currents.
The lagoon floor is composed of soft, organic-rich sediment that can be difficult to traverse during low tide.
The area is a frequent site for horseshoe crab spawning during the spring months.
Tigertail Beach Park serves as the primary gateway to the Big Marco Pass, a major waterway between Marco Island and Coconut Island.
Tigertail Beach is a coastal park on Marco Island featuring a distinctive tidal lagoon separated from the Gulf of Mexico by a sandbar. The site provides a natural habitat for diverse bird species, particularly during nesting seasons. Visitors must often wade through the shallow lagoon to reach the outer barrier beach, which offers unobstructed views of the Gulf. The beach environment consists of soft white sand and is prone to shifting topography due to tidal action. Facilities at the inland area include a playground, butterfly garden, and picnic shelters. The park serves as a major destination for shell collecting and birdwatching. Water depth in the lagoon varies significantly based on tides and recent rainfall.

Wear water shoes to protect your feet from shells and uneven terrain when crossing the lagoon.
Check the tide charts before visiting, as low tide makes the lagoon crossing much easier and safer.
Bring a waterproof bag for your phone and keys if you plan to wade across the lagoon.
Carry plenty of sunscreen and water, as there is virtually no shade once you reach the outer beach.
Attempting to cross the lagoon during high tide or with heavy equipment if you are not a strong swimmer.
Stay clear of roped-off bird nesting areas; do not remove live shells or starfish from the beach.
