I've written several travel books about Charleston, South Carolina. Here's my ultimate guide to the city.

• I'm a travel guidebook writer and I've visited Charleston many times to research features and books.
• Here are my top picks in Charleston, a city with a scenic downtown and waterfront, and great food.

As a travel writer specializing in the Deep South, Charleston, South Carolina, is a place I've visited frequently for decades. I try to make it back there at least once a year, and in my opinion, it's the best place to go in the region for an elevated level of Southern charm.

I think Charleston is one of the best-preserved cities in the United States. I love exploring the dozens of buildings that date back to the 17th century, alongside 19th-century Victorian mansions, and a picture-perfect harbor.

The city is also surrounded by outstanding stretches of coastline, with some of the South's most pristine beaches, though chances are if you're planning a visit here, food is top of mind — and for good reason. Charleston is renowned for its world-famous cuisine. I always look forward to particularly delicious seafood, and never leave without savoring a bowl of she-crab soup, a specialty.

All combined, Charleston is a destination that I've returned to time and again for both leisure and while researching travel guidebooks. Here are my favorite places I've discovered along the way to go, see, and stay.
