Isla Bella Beach Resort is Marathon's premier luxury wedding destination — a recently developed oceanfront resort on a private island at the approach to the Seven Mile Bridge, surrounded simultaneously by the turquoise waters of Florida Bay and the Atlantic Ocean. The resort's private white sand beach, turquoise infinity pool, overwater sunset pier, and Atlantic-facing ceremony lawn create multiple extraordinary wedding settings in one of the most geographically dramatic locations in the entire Florida Keys. For couples seeking a destination wedding with full luxury resort services and the Keys' iconic blue water backdrop, Isla Bella is the definitive choice in the Middle Keys.

Sunset times are calculated for this venue's coordinates, shown in EDT for the 15th of each month in 2026. Golden hour is the 60 minutes before sunset. The ceremony start is my rule of thumb — about 2 hours before sunset, so a short ceremony and family photos still leave the two of you in golden light. Adjust it to your own timeline. Average temperatures and rainfall are NOAA 1991–2020 normals from MARATHON AP, 3.3 miles away.
