Just after you enter Mississippi take the first exit, check out the info at the welcome center, then instead of going back to I10 take highway 90 down to the beaches. There are small towns, Bay St. Louis, Pass Christian, Long Beach, with local seafood restaurants on the water. Continue on eastbound to Gulfport and Biloxi where you will find casinos, restaurants, shrimp tours, lighthouse tour, and George Orr museum. You can take I110 north out of Biloxi to I10 and continue east into Alabama. It is a beautiful drive along the coast. Have fun.
