How to get to El Dorado Lake
El Dorado Lake is one of two great big lakes closest to Wichita, Kansas. To the west is Cheney Reservoir which you can get there from Wichita by taking via K-251 from US-54 and US-400.
To the east is the El Dorado Lake which you can get to from Wichita by taking via K-254. US-54 and US-77 also meet up in the town of El Dorado.
K-177 runs on the east side of the lake and I-35 runs through the north part of the lake and even cuts through a part of it. If you look on the map, you can tell that the south and the east part of the lake have more activities since it is more accessible to the two-laned highways.

Driving via K-177
Driving via K-177, you can visit the Shady Creek Area or the Bluestem Area.
Shady Creek Area
Towards the south you can find the Shady Creek Area by taking Access Road to NE 6th Street. You can find tons of designated camping areas with a boat ramp to use as well as plenty of restrooms. It will be a right turn after the park station unless you want to go to the Shady Creek Sales & Service building. If you are taking Access Road west from the highway and you don’t want to take NE 6th Street to the campgrounds, just continue west to find more excitement by the Walnut River.
Bluestem Area
To the east north of the Shady Creek Area you can find the Bluestem Area that includes some cabins, more campgrounds, and a swim beach. There are many restrooms and showers you can use to clean up, change clothes, etc. Apart from the highway and anywhere east from it the area is surrounded by the lake on both sides. This is in my opinion probably one of the cooler places to visit for the day.
