Galveston Island has lots of year-round attractions, including Moody Gardens, the Pleasure Pier and the Strand Historic District. There's also the Pier 21 Theater (with exhibits and screenings about the great 1900 storm that completely submerged the island), the Texas Seaport Museum (with the 1877 tall ship Elissa), and several historic homes, such as Moody Mansion and the Bishop's Palace. Don't limit your visit to the summer months, especially because Galveston Island is extremely popular during Halloween season. Why? Ghost tours. All those ornate cemeteries and hundreds of years of pirates, shipwrecks and devastating hurricanes, not to mention good old-fashioned only-in-Texas murders, make for plenty of ghosts. And then there was that reputedly cannibalistic Karankawa tribe. Think of it — pirates versus cannibals versus early settlers versus murderous storms. Surely, some of those spirits still haunt the island.
