Near the white sand beaches of Lovers Key, a tranquil path weaves through forests of palms and sea grapes on berms and canals returned to nature after being saved from development.
Slated to become a condo complex, Black Island on Estero Bay was cut up into an odd series of artificial canals and berms before the state purchased it. Coastal vegetation has since reforested these narrow slices of land.
Lovers Key State Park established a system of scenic trails within these tropical landscapes. The Black Island Trail covers 2.7 miles on one peninsula.
The Eagle Trail traverses 1.5 miles on a separate stretch of land accessible from a service road leading to the north end of the island.

Black Island trailheadCabbage palms and sea grapes line the winding pathway, casting patches of shade on white sandy soils.
Unique copper tinted gumbo limbos with peeling bark stand out among a forest of green leaved trees with predominantly gray trunks.
Gumbo Limbo treeAn intriguing agave known as false sisal seems to creep across the ground at the trail’s edges, searching for sunlight under a spotty canopy of sea grape trees.
Reaching a fork at 0.4 mile, turn right to begin an elongated loop portion of the trail.
Sea grapes and false sisalIn less than a tenth of a mile, the first of several covered benches sits alongside the trail, overlooking the cloudy blue water of a canal teeming with aquatic wildlife.
Passing one of three numbered shortcut trails, the path begins to climb a tall mound with a prominent stranger fig near the top.
Covered benchThe trail curves to the left at the next bench, following a thin slice of land between canals. Meander towards the end of the peninsula.
Iguanas skitter across the path and jump from trees to make an escape by plunging into the brackish waters.
Basking iguanaThe trail cuts across to the other side at 1.5 miles, passing a short side spur leading to the northernmost point before tracing along an edge of the canal.
Mangroves hug contoured banks of the berm alongside clusters of sea oxeye sporting showy yellow flowers.

The service road continues north for 0.4 mile to the trailhead and the Eagle Trail explores the innermost peninsula along a 1.5-mile loop.
