May will be a monumental month for American Cruise Lines, ushering in many exciting “firsts” for U.S. river cruising around the country. Next month, American Encore launches on the Columbia and Snake Rivers and becomes the first ship ever to be christened in the state of Idaho. May will also mark the first 2026 departures for two of the longest domestic cruises ever, the 52-Day Great United States Cruise and the 36-Day Civil War Battlefields Cruise. Each was specifically designed to celebrate the country’s 250th birthday while exploring up to 18 states in a single journey. Finally, the month of May will introduce American’s first season on the Great Lakes, featuring the only domestic cruises on the Great Lakes, all operated by American Patriot, the newest small ship in the region

“What, where, when, and how you can cruise throughout The United States today is a tremendous accomplishment that has been decades in the making,” said Alexa Paolella, spokeswoman for American Cruise Lines. “Our U.S.-flagged fleet and array of small ship itineraries honor American ingenuity, grit, and perseverance. This year, we are cruising more domestic waterways than at any other time in our company’s history, and we are looking forward to celebrating the country’s 250th birthday on board with our guests cruising from Alaska to the Florida Keys.”

Best new riverboat in the world, American Encore, launches May 5th on the Columbia and Snake Rivers, becoming the first ship ever to be christened in Idaho on May 12th (festivities to take place at American’s new dock in Lewiston).

First 250th Civil War Battlefields Cruise begins on May 5th in New Orleans, Louisiana. This 36-Day U.S. River cruise was created to honor the complex history and battles of the Civil War, and the 250th birthday of The United States (cruise concludes June 9th in Gettysburg, Pennsylvania).

American Cruise Lines’ Inaugural Great Lakes season opens May 22nd with American Patriot departing from Oswego, New York along the company’s 9-Day Great Lakes & Thousand Islands Cruise (cruise includes hotel stay in Syracuse, NY, and concludes in Buffalo, NY).

First 250th Great United States Cruise begins on May 29th in Portland, Oregon. This 52-Day bucket list cruise was specially designed to highlight the country’s diverse geography, unique cultures, storied history, and the 250th birthday of The United States (cruise concludes July 19th in Boston, Massachusetts).

American’s line-up of May “firsts” highlights the ongoing development of the domestic cruise market led by the company for over 50 years. More importantly, these advancements also illuminate the growing demand for world-class U.S.-built ships and exceptional itineraries that can be cruised a little closer to home.
