Was out geocaching the other day and stopped at Double Trouble. Sign on the park information building says the tentative dates for this years harvest is October 8 until October 11, subject to change based on leaseholder's schedule.
County has posted no parking signs all around the park entrance on Pinewald Keswick and Double Trouble Roads. Guess there were some problems last year with all the people.
The Double Trouble website has been updated recently and has more on the harvest. From http://www.state.nj.us/dep/parksandforests/parks/double.html:
Cranberry Harvest at Double Trouble State Park:
Several cranberry bogs in the Double Trouble Village section of the park are leased and maintained by local farmers. The leaseholder is on site daily; please use caution on the service roads around the bogs and reservoirs.
Unlike the days when the village's population of migrant workers would dry harvest the cranberries by hand over the course of several months, the leaseholder utilizes the modern wet harvesting technique of flooding the cranberry bogs and using machines to knock the berries off the vine. The cranberries then float to the surface of the water where they are corralled and removed from the bogs for processing. This wet harvest requires fewer people and is faster; it now takes less than two dozen people under a week to harvest the cranberry bogs at Double Trouble Village.
The harvest is open to the public to observe and usually occurs in mid-October. The public is not allowed to pick the cranberries or go into the bogs. Cranberries harvested at Double Trouble Village are taken to a central receiving station in Chatsworth and are not for sale at the park.
The Double Trouble Village cranberry bogs are located between a quarter mile and a mile walk along dirt service roads from the parking area; no vehicles are allowed in the village. As this is a weather dependent livelihood for the leaseholder, there is never an exact start or end date; the berries are harvested once they are ready to be harvested. An approximate start date as provided by the leaseholder is posted on the Double Trouble interpretive center bulletin board and voicemail (732) 341-4098 after Labor Day. Please note that this is only an approximate date that can easily change at any time dependent on the leaseholder’s schedule.
Once the harvest has started, the voicemail message will be updated. The Double Trouble Village harvest takes approximately 4 days and the leaseholder usually starts working by 9 a.m. and works through mid-afternoon, usually reaching a breaking off point sometime between 2 and 4 p.m. The cranberry harvest is not a demonstration or a festival – it is an actual harvest by the farmers who have been maintaining the bogs in the Double Trouble Historic District.
Watching the harvest is self guided; there are no harvest tours and reservations are not required. Signs at the interpretive center in the park information building will direct visitors to the cranberry bogs. Various stages of the harvest may be observed, from the flooding of the bogs to the knocking of the berries, forming the famous cranberry “raft” as the floating berries are corralled to one side of the bog, and removal of the berries for shipment to the receiving station in Chatsworth. (See Historic District Trails and Cranberry Bogs Map, for village bog locations.)
On harvest days that the Double Trouble interpretive center is open there will be scheduled tours of the early 20th century cranberry packing house that was used during the dry harvest era at Double Trouble village; there will also be a video of the dry harvest filmed at Double Trouble Village in the mid-20th century playing throughout the day in the interpretive center.
