A trail with no big climbs, nothing really technical.
The trail makes a loop around Harmon Lake. Starting from the boat ramp, head out on the singletrack going across the dam. Once over the dam, the trail meanders in and out of tree groves for a while. The trail slowly starts to turn more into open rolling fields and fewer trees.
Once across the bridge, you get into a lot of smooth trail in these open fields with the occasional tree grove. The section from the dam to the bridge is the most tricky and after the bridge the trail is easier. The more difficult section is not that bad, so most people should be fine on the trail.
There are no major uphills on this trail and nothing overly technical. Signage is good and, seeing how it is a loop, it would be hard to get lost. There are some places with really scenic views of the lake, especially around sunset.
