If you surf to the State of Hawaii Park System website (google Kalopa State Park), you can download a map of the entire park, including all the trails. There are several caches in the park, including this one on the Jeep Trail. The trailhead is at the parking lot next to the cabins (You can rent them for an overnight stay if you like this area). There is also camping, parking and picnicking available. The water is not potable, so bring your own. There are a number of trails available in the park, and you can hike for hours if you wish, or choose to do a shorter loop. The area is heavily forested with massive eucalypts and other species of tree. A great place to spend an entire day if you have it available. Hours for hiking are daybreak to dusk.
Original cache contents: travel bug, octopus wooden nickel, Where's George dollar bill, pen, log, etc.
