This weekend, Sept 12-13, marks the first annual Hudson River/Champlain Valley Heritage Weekend held on every stretch of the valley from Staten Island all the way up to Fort Montgomery in Rouses Point, NY. That's 345 miles of history, wonder, and awe.

More than 100 museums, historic sites, battlefields, and parks, many open this weekend only, will welcome visitors free or at reduced rates with special events, exhibitions, tours, hikes, performances, reenactments, and even paddles on the river. 

One of the many Heritage Weekend participating sites is Historic Hudson Valley's own Montgomery Place located in Annandale-on-Hudson in Dutchess County. Montgomery Place is a picture-perfect example of a Hudson Valley estate. Its 434 acres hold gardens, an arboretum, woodlands, and orchards. The grounds and the house will be open for free admission from 10-5 on Saturday and Sunday. Reservations are not required.
