The north end starts just off of 66th St. in Johnston, IA and it has a new piece of single track that leaves from the north lot and connects back to the main trail after 1.5 miles. The main trail (from north to south) is double wide dirt for 3.5 miles, connects to a paved trail for 2 miles, and then dips back into the woods for 1.75 miles before reaching the south end parking lot at the Polk Co. Building in Des Moines, IA. Most sections of the trail have a high line and a low line which are 50 feet or more apart with the high line staying dry more often than the low one. This is a very beginner friendly trail and the local run club holds the Sycamore 8 Mile Trail Race on it, the first Sat. of each Dec.
