Discover Mayfield Lake Park's serene waters and vibrant campgrounds.























Play all day. Stay all night. At least, that’s what we would do at Mayfield Lake Park! In terms of play, there’s lot to do: badminton, horseshoes, swimming, water-skiing, bass fishing and sunbathing. Take a little walk to Mayfield and Mossyrock dams or if you haven’t had your fill of fish, head over to the salmon and trout hatcheries. In terms of stay, you’ll be plenty cozy here. The campground is on the smaller side, but that just means more peace-and-quiet. Yesssss! If you are into those big, loud family reunions, there’s an awesome group camp tucked away from the others with a private kitchen and personal bathroom. Mayfield Lake’s immaculate reputation is met by the convenience of being located about halfway between Portland, OR and Seattle, WA—perfect for meetin’ up with your friends and playin’ the day away!
The prime time to visit Mayfield Lake Park is between April 15 and Oct. 15, when the campgrounds are open and the park is full of life. Summer months offer the warmest weather for water activities. Avoid the off-season from Oct. 16 to April 14, as the campgrounds are closed and services are limited.
