About
A Massachusetts DCR campground in Winchendon, with 70 individually mapped campsites live on ReserveAmerica's own per-site facility map (15 popup/tent, 45 tent-only, 10 non-electric). 4 additional yurt unit(s) are also bookable here but are lodging, not counted in the campsite totals above. 3 separate group camping site/area(s) are also bookable here, separate from the individual/family campsites counted above. The facility's own live per-site map also plots one or more day-use-only shelter/picnic/meeting-room markers alongside the real campsites; those are excluded from total_sites here as they are not campsites. Reservable through the Massachusetts DCR's own ReserveAmerica/Aspira contract (contractCode=MA), hosted directly at reserveamerica.com.
Fees
Campsite Fees at Otter River State Forest $17 for MA resident / $54 for non-resident. There is a $4.50 non-refundable transaction charge for each reservation made. (reserveamerica.com, live per-facility fee notice)
