The Hudson River is about 507 km long in the state of New York. It winds southeast for 172 km until it reaches Corinth and then turns northeast to Hudson Falls. It flows directly south into upper New York Bay. The basin covers an area of 34,628 square kilometers . A submerged valley extends about 320 km seaward from the mouth of the river. Together with its main tributary, the Mohawk River, it forms one of the most important waterways in the country.

The Source of the Hudson River is Lake Tear of the Clouds, 1,317 meters above sea level, in Adirondack Park. It should be noted that the stretch of river several miles from its source on maps is not listed as the Hudson River but as Feldspar Brook, the same name as the Calamity Brook after it confluence with the Calamity Brook. It then joins Indian Pass Brook and flows south at the mouth of Henderson Lake. At this point, the stream was officially called the Hudson River.

The Hudson River is a great place to go for a hiking, with lots of scenic spots, natural scenery and lots of farms.

The Hudson Valley has a long agricultural history, as it was settled with agriculture being its main industry. Around the 1700s, tenant farming was highly practiced. The farms' main products were grains (predominantly wheat), though hops, maple syrup, vegetables, dairy products, honey, wool, livestock, and tobacco were produced there. The region became the breadbasket of colonial America, given that the surrounding New England and Catskills areas were more mountainous and had rockier soils. In the late 1800s, most farms transitioned from tenant farming to being family-owned, with more incentive to improve the land. Grain production moved west to the Genesee Valley, and so Hudson Valley farms specialized, especially in viticulture, berries, and orchard cultivation. Agriculture began to decline in the 19th century, and rapidly declined in the 20th century.
