Sherwood Forest - One forth the acreage, more speedball oriented.
The Paintball Zone - About the same size, another good Rec field.
I'll start by stating this - I'm a recreational player and I love paying in the Woods! The Paintball Jungle is about 65 acres of trees, brush, bunkers and five major structures. It has three significant areas, Zulu Territory, The Speedball area, and The Jungle.
The Jungle frequently draws 150+ players on each day of the weekend but there is plenty of room and cover. This makes for a target rich environment! If you want to play speedball the jungle will be disappointing.
