Outdoor enthusiasts have something to celebrate this month, when the Hudson River Valley Greenway and National Heritage Area hosts its 15th annual Ramble. The event encourages valley residents and visitors to take advantage of the historic and ecological sites in the region, stretching from Albany County down to the Bronx. It's truly a community effort—this year's Ramble will include over 200 events organized by 150 partner organizations, including bike tours, hikes, river paddles, and historic site tours. Music connoisseurs can look forward to the Albany Riverfront Jazz Festival on September 6, apple addicts will love Peach Hill Park's Apple Cider Ramble on the 28th, and history buffs won't want to miss tours of the Revolutionary War Headquarters in Fishkill. Events run every weekend in September. (518) 473-3835; Hudsonrivervalleyramble.com.
