Carnival Horizon

Moody Gardens

Three glass pyramids rising out of a Gulf island, each housing something more elaborate than the last — an aquarium, a rainforest, a 4D cinema. Pack for a half-day; the penguin habitat alone has been known to delay cruise departures.

🕒 Daily 10 AM – 6 PM (extended summer hours; verify seasonally)

Bishop's Palace

An 1892 Victorian castle a Galveston lawyer and colonel built to out-Victorian the Victorians — turrets, stained glass, carved fireplaces, the works. Ranked among America's great houses; no argument from anyone who has seen the staircase.

🕒 Tue–Sun 10 AM – 5 PM

Elissa

An 1877 iron barque that sailed the world's trade routes for nearly a century, now Texas's official tall ship — and you can board her, which puts her ahead of most state symbols. Still seaworthy; moored at the Texas Seaport Museum waterfront.

🕒 Daily 10 AM – 5 PM (verify seasonally)

Galveston Seawall

A 17-foot concrete wall built after the 1900 storm killed thousands — Galveston's version of 'never again.' Free to walk or bike, with big flat Gulf views and a promenade long enough to settle most arguments.
