Deerfield Lake Loop Trail is a 10 mile loop trail located near Hill City, SD and is rated as moderate. The trail is primarily used for hiking and is accessible from April until October.
A bit longer than 10 miles, trail is nice by the lake side, not marked as well as I would have hoped for the rest.
Just a great hike! Did not expect much at first but the longer we went the better it got. Lots of vegetation changes and views of this beautiful lake. Went past some great primitive camping site one guy out fishing in an inflatable. Lake is stocked with trout limit one. Somehow this turned into about a 14 miler and as mentioned the trail
Markings while generally good get sketchy in places. We lost the trail once and had to follow a fence line to
Regain. Not much elevations but overall fun!
Great for hiking, not for mountain biking due to terrain and inclines and numerous gate crossings. Very pretty view. Occasionally not well marked. Plan on a full day
