Bur Oak Trail
by

32 Completed 29 Reviews

Bur Oak Trail begins near where the new visitor center for Good Earth State park is being built not far from the gravel parking lot. It goes in a Northerly direction around an old farmstead with a barn and silo. It's a 2 wheeled dirt road for a short distance and then veers to the right where it is a mowed grass path that stays near the trees. Then it descends to the river bottom through a dense oak stand and goes past a grave marker for the first child to have died in Lincoln County. The loop begins as you reach the river bottom where it opens up to prairie grass. The loop gives some views of the Big Sioux River then steadily climbs back up to finish the loop and then back to the trail head in more of a lollipop trail style. At 2.5 miles it's a nice distance for a hike in under an hour yet not too short. Look for the 3 oaks growing in a row along the path. Good path to view wildlife late evening or early morning

Valley of the Giants

This trail is mostly a heavy canopy of trees that makes for a nice hike on a hot day. It begins next to a Gazebo in the park and comes out to the asphalt bike trail that finishes the loop. Mature Oak and Giant Cottonwood trees are predominant. The trail descends to the river bottom where you get close looks at the Big Sioux.

Prairie Vista Trail

This trail has big views and is a good length for a workout. The beginning goes through a disc golf course and could be a little confusing the first time through. Just head West until you get to the footbridge over the river. I hiked it counter clockwise and after you cross the foot bridge you go up and up to the top of the ridge. Big breezy views await. Prairie and few trees on this trail. Great for keeping bugs away in the breeze. Dirt trail then loops down to the Big Sioux River and then back to the trail head.

Cactus hills Trail

I like this quiet trail as it is a little longer than some of the others at Great Bear if you begin from the parking lot near the lodge. There's a grassy knoll at the top of the trail. Well marked trails. There are other short connecting trails so that if you get bored you can change up your route.

Skyline Trail

This trail leads up to a high point with a nice view to the West and the city of Sioux Falls. A couple of steep portions of the dirt trail make it a little more challenging than some of the others at this recreation area.

Very Easy short trail. Is a nice quiet trail with a very picturesque pond and footbridge. Saw wild turkeys and signs of other wildlife.

This spur trail begins at Sertoma park and goes along the West side of the Big Sioux River and then joins Skunk Creek where it enters the big Sioux. At a good pace you can do this in 40 minutes out and back.

Riparian Trail

This trail goes along the Big Sioux River with nice views of the river, river bluffs and a couple of Massive Cottonwood trees along with a very large maple that creates an arch over the trail. It's a loop that begins more than a mile from the parking area. You must take the Bur Oak trail or another connector trail to get to it. A good workout, Great views, and low traffic make this a great trail to get out for some solitude.

Harney Peak - South Dakota Highpoint

This was one of our favorite hikes. We took trail 4 up, trail 9 back. Do watch for thunderstorms, we were at the top and the clouds rolled in quite suddenly. We got halfway down the mountain and got caught in a thunderstorm complete with hail. At least the terrain on trail 9 was fairly easy and allowed us to pick up the pace! The rain was gone just as quickly as it came by the time we reached the bottom of the mountain and we were soaked to the skin. Our family (kids 18, 12, 9) agreed this certainly made the hike very memorable.
