Lonely Planet, one of the world's most iconic travel guides, named the Catskill region one of its Best in Travel 2019 Top Regions. From the article:
This beautiful mountainous region west of the Hudson Valley has been a popular getaway since the 19th century. The romantic image of mossy gorges and rounded peaks, as popularized by Hudson Valley School painters, encouraged a preservation movement: in 1894 the state constitution was amended so that thousands of acres are 'forever kept as wild forest lands.'
