Yes, Roosevelt Island is absolutely worth visiting in 2026, especially for the unique "aerial" experience of the Roosevelt Island Tram. For the price of a standard NYC subway fare, you get a 4-minute ride with stunning views of the Manhattan skyline and the Queensboro Bridge. Once on the island, the atmosphere is remarkably quiet and residential compared to the bustle of Midtown. Key highlights include the Franklin D. Roosevelt Four Freedoms State Park at the southern tip, which offers a serene granite memorial and panoramic views of the UN Headquarters. You can also explore the historic (and slightly eerie) Renwick Ruin, the site of a 19th-century smallpox hospital. With its waterfront promenades and "hidden gem" status, it is a high-value escape for anyone looking to see New York City from a completely different perspective without leaving the borough of Manhattan.
