Shelter Area
A paved pathway connects the accessible shelter and a nearby shady picnic site to two handicap parking spaces. The pathway has a maximum slope of 5.8% for 20 feet just before reaching the shelter. The shelter accommodates 60 people and provides a group grill and extended-end tables. The individual picnic site has a pedestal grill and an extended-end table and is adjacent to the area's water fountain. A flush restroom is conveniently nearby for all users.

Historic Area
Just up the slope from the shelter is the old Hickam Cabin, which is representative of the architecture in the late 1820s to early 1830s in this area. It sits on a grassy knoll and can best be reached from the office parking lot for visitors who may be restricted by slopes. Access is over natural turf.
