Captiva & sandbar route guide
Captiva, Redfish Pass sandbars, and the Cayo Costa option
The route: Cape Coral to Captiva and Redfish Pass
Follow the Sanibel route through the Caloosahatchee and San Carlos Bay, then continue west past the Sanibel Lighthouse. The channel runs along Sanibel’s north shore through Pine Island Sound toward Blind Pass, the narrow cut between Sanibel and Captiva.
Once past Blind Pass, Captiva Island opens up to the north. The village area has waterfront dining and the iconic Bubble Room restaurant. Roosevelt Channel on the east side of Captiva is a calm, scenic stretch named for Teddy Roosevelt, who fished here regularly. Continue north to reach Redfish Pass—the channel between Captiva and North Captiva Island—where shifting sandbars create the area’s most popular boat anchorage.
Sandbars at Redfish Pass: timing and conditions
The sandbars near Redfish Pass shift with currents and storms, but they reliably appear during low tide as shallow wading areas with clear turquoise water. Plan your arrival around the tide chart—two hours before through two hours after low tide is the sweet spot.
On weekends and holidays, the sandbars can get crowded with local boaters. Weekday trips are noticeably quieter. Current through the pass itself can be strong, so anchor on the sandbar edges rather than in the channel. Keep an eye on the tide—what was ankle-deep at low tide can be waist-deep an hour later.
Side trip: Cayo Costa State Park
If the day and fuel allow, Cayo Costa is just north of North Captiva—roughly 20 minutes from Redfish Pass. This barrier island has nine miles of completely undeveloped Gulf beach, accessible only by boat. The state park protects 2,500 acres of pine forest, mangrove wetlands, and oak-palm hammocks.
Four species of sea turtles nest on Cayo Costa’s beaches. Bottlenose dolphins are common along the shoreline, and manatees frequent the dock area. Entry is $2 per person via honor box. The park is open 8 a.m. to sundown. There is no food service on the island, so bring everything you need. This is widely considered the best shelling destination in the area—even better than Sanibel for serious collectors.
