Just under 100 miles from Manhattan, the Hudson Valley has long been a beloved vacation spot among New Yorkers seeking a serene, easy escape from the city. In recent years, the region has — and continues to — grow in popularity, ushering in dozens of buzzy new restaurants, bars, and accommodations. However, one Hudson Valley institution that has withstood the test of time is Mohonk Mountain House, a Victorian castle resort and National Historic Landmark that looks like it’s been plucked straight out of a storybook. The family-friendly, all-inclusive oasis (consistently named one of the best hotels in the U.S.!) has welcomed guests since 1869, and most of its dedicated staff has worked there for decades. We tapped two of the resort’s concierges — Diane and Regina, who have worked at Mohonk for 17 and seven years, respectively — to reveal how to make the most of your stay here.
