Forge further north along the Georgia shore, beyond St Simons Island, and you roll into one of America’s oldest cities. Savannah was founded in 1733 – but its epic heritage does not have to be daunting for youngsters. The Savannah Safari is a free downloadable trail which guides children around the key sights – such as the spooky Colonial Park Cemetery, a graveyard which dates to 1750.
There are exciting 20th-century tales, too, at the Mighty Eighth Air Force Museum (adults £6, kids 6-12 £3.50) – where fighter planes and stories of derring-do salute some of Georgia’s Second World War heroes. And if this adds up to too much history, sugary compensation can be found at Leopold’s Ice Cream – an old-fashioned parlour with 21st-century flavours (such as mocha chocolate chip, and chocolate raspberry swirl).
Some 15 miles to the east, Tybee Island is the city’s seafront companion (to the extent that it was once marketed as ‘Savannah Beach’ ). There is much soft sand here – but also child-friendly ecology at Tybee Island Marine Science Center (tickets £2.50), which looks after injured Carolina Diamondback Terrapins. Island biologist Dr Joe Richardson, meanwhile, runs Tybee Beach Ecology Trips, which explore the rock pools and dunes of this pretty outpost (price varies according to group size).
There’s plenty of room in this comfortable air-conditioned ride that’s perfect for large families taking a trip out of state.
