I placed this in the winter, so spring and summer growth will make this one more difficult to access. Although the easiest access to the cache is from the B&A Trail, you can access it from outside of the park. The cache is not in the park, but if you access it from the park you'll be limited to daylight hours. The park hours are "Dawn to Dusk". Please respect that. I did not enter the area from the nearby establishment.
The parking waypoint provided is also Dawn to Dusk, please obey all signage.
