Explore the Grainfield Area

Hit the dump station during off-peak hours if possible -- late morning or early afternoon usually sees lighter traffic than evening hours when everyone's trying to get back on the road. The rest area dump station includes a rinse hose, but bring your own drinking water since the spigot isn't designed for tank filling.

Fuel up before you dump since the nearest gas stations are back in town, about 2 miles from the rest area. Casey's General Store on Main Street offers diesel and has a decent-sized lot if you need to grab snacks or supplies. For propane, you'll need to head east to Hays or west to Oakley -- neither option is particularly close.

The dump station can get busy during peak travel seasons, especially summer weekends when folks are heading to Colorado camping destinations. If you encounter a line, be patient and have your gear ready to speed up the process. Winter dumping here can be brutal with the wind, so dress accordingly and consider waiting for calmer weather if possible.
