Lafayette to Gulfport Road Trip: Bayou to Beach Guide

Just after the Vermilion River bridge on I-10 east of Lafayette, the bayou cypress give way to a horizon that flattens into marsh and sky.

The drive covers roughly 275 miles and takes about 4 to 4.5 hours without stops.

Highways and Navigation

The primary route uses I-10 east from Lafayette, then US-90 east from New Orleans through the Mississippi Gulf Coast.

Natural Landscapes & Attractions

The most dramatic landscape change is crossing the Atchafalaya Basin between Lafayette and Baton Rouge (miles 100–155 on I-10).
