Watch for the Park signs on Hwy 32 as you approach the turn-off. The Whispering Pine Trail is a 10 mile trail made up of a 6 mile north loop and a 4 mile south loop to give a combined total of 10 miles if you hike the outside of both loops. This trail also adjoins the one-mile Pickle Creek Trail. Water is readily available in Pickle Creek, a beautiful clear stream, but you will need to filter or treat it. One will hike along Pickle Creek on the west side of the north loop.
Overnight parking is available at the trailhead in the park.
I had always heard that this was a beautiful trail and I finally found out first hand that it is very beautiful. The hike along Pickle Creek and the bluffs on the west side of the north loop was spectacular and well worth the trip. It often gets crowded in this park due to its proximity to St. Louis so take off during the week and go when it is quiet. My hiking partner and I only ran into one person during our trek along the north loop. A few shut-in areas along the creek make for a great picture and a peaceful stop to ponder the beauty of the place.
