We mapped it last week at 1.9 miles and took 1 hr 15 min with a 10 y/o, 6 y/o, and our dog. However, we did walk down one small side trail but it wouldn't have been more than an extra 0.1
The trail book says 1.6 miles and that it will take about 1.5 hours at a leisurely pace. It took me longer because the last half is uphill. I had to stop and rest. There are benches along the way.
