This is about a 6 mile out and back hike along the Green River Cove trail. (Or about a 5 mile out and back hike along the Pulliam Creek trail.) The 6 mile hike has less elevation gain/loss, but you do you.
Enjoy the river. Enjoy the kayakers. Enjoy the widlflowers. Enjoy the creek crossings. And don't forget to look for the cache, which is a small blue water bottle. The log is pink survey tape, which is waterproof.
