Where Caxambas Pass sits
Run down to the very bottom of Marco Island and you hit Caxambas Pass — the southern inlet, opposite Big Marco and Capri Pass up at the island’s north end. It’s tucked behind the southern beaches, fed by the back bays, and it opens toward the lower Gulf and the start of the Ten Thousand Islands. There’s a county boat launch and marina here, which is why so many trips — ours included — use Caxambas as the jumping-off point for everything to the south.
The water through the pass moves with the tide like any inlet, scouring channels and holding bait, which is exactly what makes it such a good fishing spot.
Calusa roots & the old Caxambas village
The name Caxambas comes down from the Calusa, the shell-mound people who fished this coast for a thousand years, and a real village stood here on those mounds well into modern times. Old Caxambas was a working fishing and clamming community — there was even a clam cannery operating in the area in the early 1900s — before Marco grew into the resort island it is today. You’re running out through a pass people have launched from for centuries. If that history hooks you, our deep dive on Caxambas village history tells the whole story, and it ties straight into the broader Calusa story at Key Marco.
| Pass | Location on Marco | Known for |
|---|---|---|
| Caxambas Pass | South end | History, launch & fishing; route to Kice & Cape Romano |
| Big Marco Pass | North end | Sand Dollar Island bar & bird habitat |
| Capri Pass | North tip / Isles of Capri | Deep dolphin water |
Gateway to Kice & Cape Romano
Here’s why we love starting a day at Caxambas: point the bow south and the wild stuff is right there. A short run drops you on Kice Island, a boat-only barrier beach with some of the best big-shell hunting near Marco, and a little farther on is Cape Romano with its broad shoals — and offshore, the half-submerged ruins of the old dome houses that Hurricane Ian toppled in 2022. They’re ruins now, not the standing curiosities they once were, and they’re still one of the most striking sights on the coast. Along the way the pass and the back bays hold redfish, snook, trout and more, which is why our Marco Island fishing charters often work this water.
Whether you’re after empty shells on Kice, the eerie dome ruins, or a backwater fishing day, Caxambas Pass is the launch that gets you there fast. Book a shelling tour and we’ll run you straight out the historic south inlet.
From the Helm: Choosing the inside line past the oyster bar at Caxambas Pass
Heading south out of Marco, the first call we make most mornings is which way we’re running out through Caxambas Pass — hugging the inside edge past the oyster bar, or swinging wide through the deeper cut closer to the Gulf side. A stiff onshore wind against an early falling tide is what pushes us toward that wider cut; anything calmer and we’ll thread the inside line and save a few minutes getting south.
That inside route runs close enough to a working oyster bar that we idle the whole stretch and keep the outboard trimmed up — oyster rock will open a lower unit in a hurry if you’re not paying attention, and the bar itself shifts enough season to season that we re-walk the line mentally on every trip rather than trust last month’s memory of it.
Guests at the rail through here usually catch the smell before anything else — that low-tide, mineral smell of exposed oyster rock and mud that’s as much a part of this pass as the water itself. A little further in, a back creek splits off toward the mangroves, and we’ll sometimes idle in just far enough to let the engine noise fall away and listen for whatever’s moving in there.
On days the outside bar at the pass mouth is standing up rough — usually a west wind fighting an outgoing tide — we’ll delay the run by twenty or thirty minutes and let the tide settle rather than punch through a stack of short chop right at the inlet. It costs us a little time at the dock, never a good ride once we’re out in it.
We also like clearing the dock before the wind fills in for the day. First light through Caxambas Pass is usually glassy, the oyster bar barely rippling and the whole inside line easy to read; by early afternoon the sea breeze has typically kicked up enough chop that the same stretch feels like a different pass entirely. It’s a big part of why our earliest departures tend to be the smoothest ones we run all week.
We also brief the plan differently depending on which route we take. Running the inside line past the oyster bar means everyone stays seated and idle-slow for a stretch; running the outside cut means a livelier ride with more spray off the bow. Neither is wrong, but we like guests to know which one they’re getting before we ever clear the dock lines.
Caxambas Pass has been the working route south since long before recreational boats ever ran it, and it’s still how we reach Cape Romano and the wilder keys beyond it, whether we’re out on a shelling tour or running further south still.
