Exploring the Spoil Islands of Fort Pierce: A Hidden Treasure of the Indian River Lagoon
Posted on December 21st, 2025
Tucked quietly along the eastern edge of Florida’s Treasure Coast lies one of Fort Pierce’s most fascinating and least-understood natural treasures: the Spoil Islands. Scattered throughout the Indian River Lagoon, these low-lying islands offer an extraordinary blend of history, wildlife, and scenic beauty. For visitors and locals alike, the Spoil Islands represent a rare opportunity to experience “Old Florida” — wild, peaceful, and deeply connected to the natural rhythms of the lagoon.
For many years, guided eco tours operated by Motorized Kayak Adventures have introduced guests to these remarkable islands, helping them understand not only what they are seeing, but why the Spoil Islands are so important to the long-term health of the Indian River Lagoon.
What Are the Spoil Islands?
The Spoil Islands are man-made islands created during dredging projects intended to maintain and deepen navigation channels within the Indian River Lagoon. The dredged sand and sediment — known as “spoil” — was placed above the waterline, forming dozens of small islands throughout the lagoon system.
What makes the Spoil Islands special is what happened next. Over time, mangroves took root, native plants stabilized the soil, and wildlife quickly colonized the new land. What began as piles of dredged sand evolved into thriving ecosystems that now support birds, marine life, and coastal species year-round.
Today, these islands are among the most ecologically productive areas of the lagoon and a highlight of many motorized kayak tours in Fort Pierce.
A Vital Part of the Indian River Lagoon Ecosystem
The Indian River Lagoon is one of the most biologically diverse estuaries in North America, and the Spoil Islands play a critical role in that diversity.
Mangrove shorelines protect the islands from erosion while creating nurseries for juvenile fish, crabs, and shrimp. These sheltered waters help sustain the food web that supports dolphins, birds, and larger predatory fish. The islands also provide safe nesting and roosting areas for wading birds, away from predators and human disturbance.
Guests on guided Spoil Islands kayak tours often see how interconnected the lagoon ecosystem truly is — from fish darting through mangrove roots to birds feeding along the shoreline and dolphins cruising nearby channels.
Wildlife Commonly Seen Around the Spoil Islands
The Spoil Islands are a wildlife hotspot, making them a favorite destination for nature lovers, birdwatchers, and photographers.
Birdlife commonly includes pelicans, great blue herons, snowy egrets, roseate spoonbills, ospreys, and bald eagles. During nesting season, some islands become active bird colonies filled with constant movement and sound.
Marine mammals such as bottlenose dolphins are frequently seen, often surfacing close to kayaks. Manatees are also common visitors, particularly during warmer months.
Because of the quiet, low-impact nature of kayaking, wildlife photography kayak tours in this area are especially rewarding.
Why Kayaks Are the Best Way to Explore the Spoil Islands
Kayaks offer a quiet, low-impact way to explore these sensitive environments. Unlike larger boats, kayaks can glide silently through narrow channels and shallow water without disturbing wildlife or damaging seagrass beds.
Motorized kayaks add an important benefit: they allow guests to explore more of the lagoon comfortably, regardless of age or physical ability. This makes the Spoil Islands accessible to seniors, families, photographers, and visitors who want a relaxed yet immersive eco-tour experience.
For many years, Motorized Kayak Adventures has been conducting guided kayak tours to the Spoil Islands, combining effortless travel with expert interpretation and environmental education.
A Deep Connection to Conservation and Preservation
The Spoil Islands are not just scenic destinations — they are fragile ecosystems that require thoughtful protection. Conservation efforts over the years have focused on preserving bird nesting areas, restoring mangrove habitat, and educating the public about responsible use of the lagoon.
A key part of that conservation story is the creation of Friends of the Spoil Islands, an organization founded specifically to help protect and preserve these islands.
The owner of Motorized Kayak Adventures was the founding president of Friends of the Spoil Islands, helping establish the organization to advocate for habitat protection, responsible access, and public education. That leadership reflects a long-standing commitment not only to sharing the beauty of the Spoil Islands, but also to ensuring they remain healthy for future generations.
History Beneath the Surface
Beyond their ecological importance, the Spoil Islands tell a story about Florida’s changing waterways. Created during mid-20th-century dredging efforts, the islands illustrate how human activity and natural recovery can intersect.
In just a few decades, these once-barren sand piles transformed into thriving habitats — a powerful reminder of nature’s resilience when given time and space to recover.
A Photographer’s Dream Location
With calm waters, dramatic skies, and abundant wildlife, the Spoil Islands are a paradise for nature photographers. Sunrises and sunsets cast golden light across mangroves and water, while birds and marine life provide constant photographic opportunities.
Many guests combine these experiences with private kayak tours of the Indian River Lagoon, allowing extra time for photography and exploration.
