The arboretum is very unique. It has gravel trails and grassy trails that guide you through the arboretum. There are signs indicating which trail you are on, but without the printed map to accompany the signs, they can be confusing.
The park is divided into approximately 1/3 trees with gravel trails, 1/3 tall grass and scrubs with grassy trail, and 1/3 trees in the woods with dirty trails. I highly recommend wearing hiking shoes or athletic shoes. Sandals are not recommended because your feet can get very dirty from the dirt and gravel.
I went in early October and there was no bugs. During other time of the year, recommend preparing yourself with bug spray. Not to worry, if you forgot the bug spray, the arboretum is kindly to provide some. Once you exit the visitor center/gift shop where you pay for your admission, you will find bottles of bug spray available for you to use. The restaurant is also in the visitor center/gift shop. If you are traveling with your pets, pets are welcome and please pick up after your pet.
The arboretum also has a fenced in area for goats. There was a family of goats when I was there, and my dog just loved them as they loved my dog. The second they noticed my dog was approaching, the goats came out of their little house and started slowly walking toward us. They were curious, and my little dog wanted to play with them. That was the highlight of our visit.
