This is a very relaxed trip with friends that are brand new to backpacking. Total mileage is about 22 miles. Although we will almost definitely be traveling faster than 1 mile per hour, I calculated it at 1 MPH to allow breaks at scenic areas, to sleep in, or to rock hop on the Little Carp River. Here goes:
Arrive at Big Carp River trailhead at 5 PM. Hike Southwest 4 miles, stopping at campsite #1. Eat a no cook dinner and go to bed.
Wake up at 8 AM. Make breakfast, break camp, and start hiking by 10 AM. Hike 7 miles West and then South to campsite number 2. Arrive at campsite at around 5, then make campfire, set up tarps, and make dinner before bedtime.
Similar to day 2, hiking 7 miles East and then Northeast to campsite #3. Make fire, set up tarps, and eat dinner.
Start hiking at 10 AM, and hike the remaining 4 miles North back to the Big Carp River trailhead.
