December 6 My own private Idaho by Alex Gaston
park review stars; one to five I had a great time. Truly one of the most beautiful spots in the world. I am glad my children got to see what I had when I was their age.
September 21 Breathtaking!! by Amy
park review stars; one to five Harriman Sate Park is wonderful in every season. I often come during the fall and witness the elk rutting season. It is amazing with migratory birds, less people and the amazing sounds at sunset and after of the mating elk. I love this place and have seen moose, eagles, swans, pelicans, bluebirds, bats, snakes, all sorts of ducks, an Ibis !!!, osprey, blue heron, and elk. Come and pay your fee to support this majestic place. Also, in the summer - take the tour of the houses & ranch. You can also stay here overnight! What an incredible history - from Harriman to the Guggenheims.
