Another hike that I like is the Johnson Lake Loop in the UAF Experiment Farm portion of the MatSu Greenbelt trails. The hike winds up being a couple of miles and is easy walking.
For more info on the Matsu Greenbelt Trails and to download maps, visit their website here...
To access the trail, park at Kerttula Hall. To the north of the building you'll see the trail head sign and map. The first part of your journey will be going through the farm's working area. Please stay out of the barns and avoid any moving equipment.
Here are the pictures (you can click on them to enlarge):
