Milford Lake KOA Holiday will open April 1, 2026. Many may know us by our previous name, Flagstop RV Park. The park is open April1-October 31. We are located in Milford, Kansas, about 12 miles from Interstate 70 and nestled in a scenic setting with large, mature trees. Milford Lake is visible from all sites. There is a gated entrance into the park. Guests are given a personal gate code. There is a separate exit.
We offer many different types of RV sites. Sites just right for a small camper van or a large Class A motorhome. We offer full hookup or just water and electric and 30- or 50-amp service. However, all sites include complimentary cable and Wi-Fi. We have new bathhouses and a new laundry facility for your convenience. The recreation building is a great gathering spot. Plenty of space indoors or grab a table outside on the deck. On weekends, we will offer biscuits and gravy and sometimes a pancake breakfast.
Many different plans are available for your stay. Nightly, monthly, or seasonal plans are possible. We welcome groups also. Come enjoy our cabins. All cabins include a spacious patio area to enjoy the great outdoors. There are four dual RV/tent sites with 30 amp service and water. Close to restrooms.
Of course, Milford Lake is the main attraction. Sunrises and sunsets are equally breathtaking. There is nothing better than making s'mores over a crackling campfire after a long day enjoying the lake.
There are so many things to do here. There's a great playground with a jumping pillow. Basketball, Volleyball, and Gaga Ball will keep you moving. There is a beach area for walks or maybe a swim. Don't forget our lakeside Kamp K-9 for our 4 legged friends. Pets are welcome almost everywhere at our park.
The fish cleaning station is open for those who have had a good catch on the lake. Yes, bring your boat. Most RV sites are long enough to accommodate your boat, catamaran, or canoe. If you need more space, there is a storage lot.
The Campground is conveniently located near many local attractions, dining, and shopping. Junction City and Manhattan are close and offer a wide range of choices. Our staff is happy to offer suggestions or provide information.
