Grand Lagoon is a sheltered coastal waterway near Panama City Beach, Florida, renowned for its calm waters, abundant marine life, and easy access to St. Andrews State Park.
Grand Lagoon is a natural tidal waterway separating the southern tip of Panama City Beach from the western edge of St. Andrews State Park in Bay County, Florida. Shaped by centuries of sediment movement and tidal exchange with the Gulf of Mexico through the St. Andrews Pass, the lagoon has long served as both a working waterway and a recreational resource for the communities along its banks.
The lagoon's calm, protected surface makes it a natural habitat for a wide range of coastal wildlife. Bottlenose dolphins follow the channel looking for mullet, while brown pelicans cruise overhead and dive without ceremony into the shallows. Anglers prize the grass flats for redfish, speckled trout, and flounder, and the deeper channel holds Spanish mackerel during seasonal migrations.
On the water, kayaking and paddleboarding are the most intimate ways to explore Grand Lagoon, letting you drift close to the mangrove edges and sandy shoals that powerboats pass by. Boat tours operating from the marina areas near St. Andrews Pass offer dolphin-watching trips that move between the lagoon and the open Gulf, giving visitors a broad sense of the ecosystem.
The surrounding area adds to the appeal, with St. Andrews State Park providing hiking trails, snorkeling at the jetties, and some of the most consistently praised beaches on the Panhandle. Grand Lagoon anchors this stretch of coast as a place where natural beauty and accessible outdoor recreation meet in a setting that remains genuinely tied to its Gulf Coast character.
Visit during the week in late spring or early fall to enjoy calmer waters and fewer boats sharing the lagoon.
Try fishing for flounder and redfish along the grass flats on the eastern shore, where the water shallows gradually.
Bring polarized sunglasses to cut the surface glare and spot dolphins and rays moving through the clear, shallow water.
Launch a kayak or paddleboard from the boat ramp near St. Andrews State Park for direct access to the lagoon's quieter coves.
Arrive early in the morning when the water is glassiest and the light turns the lagoon a vivid turquoise before the afternoon wind picks up.
