The extraordinary, often bizarre treasures housed in America's museums represent wondrous chapters in history, but a physical display can tell only part of their story. Behind each artifact are amazing tales and secrets to be revealed -- tales sometimes brimming with scandal, mystery, murder and intrigue. In "Mysteries at the Museum," host Don Wildman visits a wide variety of museums across the United States, taking viewers on a sometimes shocking tour of America's past by re-examining what's been left behind. Interviews, archival footage and re-enactments bring to life the artifacts' enduring mysteries, some that have never been told before on television.

Travel Channel's fascination with mysteries grows with this series, adding it to a catalog that also features "Mysteries at the Castle," "Mysteries at the Museum" and "Monumental Mysteries." America's vast network of national parks -- dense expanses of virtually unexplored wilderness -- offers breeding grounds for the unsolved and unexplained. Each hourlong episode presents several perplexing stories detailing unusual events at sites including Montana's Glacier National Park, Pennsylvania's Gettysburg National Military Park, California's Shasta National Forest, and Puerto Rico's El Yunque National Forest.

From the inspirations for Mary Shelley's "Frankenstein" to Alexandre Dumas pere's "Man in the Iron Mask," the series "Mysteries at the Castle" (formerly called "Castle Secrets & Legends") features visits to stunning palaces, amazing manor houses and magnificent mansions throughout the United States and around the world, revealing some incredible stories that are contained within them.

This show takes viewers on a tour across the U.S. to visit mysterious and spooky paranormal hot spots. Locations vary from world-famous businesses to humble homes, each with its share of ghost sightings and unexplainable phenomena. Notable sites profiled in the series include the Liar's Club in Chicago, the Shanghai Tunnels below Portland, Ore., and the Stanley Hotel in Colorado, which provided inspiration for Stephen King's "The Shining."

As the host of numerous Travel Channel docuseries aimed at exposing truths lying beneath the surface, Don Wildman has ventured deep into the vaults of America's most revered institutions and unearthed wondrous treasures from the past. In "Beyond the Unknown," Wildman's adventures continue, as he seeks to answer history's biggest questions and explores the most astonishing and explainable events in recorded time. Each story features interviews, archival footage and stylized reenactments.

While the title of this popular series has changed (formerly called "Samantha Brown: Passport to Great Weekends") the end result looks just as relaxing. Capitalizing on the growing trend among American families to take weekend trips in lieu of the traditional one- or two-week vacations, Samantha visits popular weekend destinations ranging from San Francisco, New York and Orlando, Fla., to Paris, with each trip built around a theme (a Washington, D.C., visit that de-emphasizes the usual historical monuments and museums, for example).

Don Wildman takes his thirst for adventure into terrifying new territory to explore mankind's darkest mysteries.

In one of the most popular series in Travel Channel's history, actor Casey Webb -- assuming the mantle from original host Adam Richman -- travels across America to sample some iconic regional dishes and take on some daunting food challenges, such as attacking a pitcher-sized bloody mary garnished with a whole fried chicken, tucking into a four-and-a-half-pound Reuben sandwich, and a choice between taking on a 151-ounce milkshake, an eight-pound sloppy joe or eating six habanero ghost chili wings. Talk about the big, the bad or the burn!

Intrigued by legendary mysteries and driven by curiosity, Josh Gates is on a mission for answers. "Exhibition Unknown" chronicles his global adventures as he investigates iconic unsolved events, lost cities, buried treasures and other puzzling stories. Armed with a degree in archaeology, a quick wit and a thirst for action, Gates investigates recent developments before embarking on a detailed exploration. Whether he's trekking through Fiji in search of Amelia Earhart's remains or diving the deep seas of Panama to locate Captain Morgan's pirate ship, Gates' roughshod expeditions lead him one step closer to the truth.

Possessed by a strong curiosity and, apparently, an even stronger digestive system, host Andrew Zimmern (a chef and food writer by trade) traverses the world in pursuit of unusual regional delicacies and startling native "delights" on the menu, as he tries to ferret out the weirdest foods a location has to offer -- possibly including ferret, actually. In addition to vivid descriptions of the taste and texture of the foods he discovers, Zimmern also provides a short history of each dish. Some of the locales Zimmern has traveled to include Ecuador, Taiwan, Iceland and Minnesota (because not all "unique" foods are found in exotic locations).
