I have provided a Waypoint for the Parking Lot, which is where the Main Trailhead is located, in addition to the Kayak Launch.
There is also a Disc Golf Course and Activities/Display Center to keep your non-Caching Friends entertained.
On your way to the Parking Lot you pass the Playground (with it’s own Parking Lot) and Restrooms.
Ground-Burns are performed regularly here but are scheduled no more than two Days in advance, so there is a chance that you may not be able access all Areas of the Preserve on the Day you are there
For more information about the Preserve: https://grahamcreekpreserve.org/
Choose your approach carefully, step wisely and the Terrain Rating will drop...unless it has rained in the last two Days.
