Our Mission
Friends of Interstate and Straight Lake Parks is a non-profit organization established with the purpose of supporting, assisting, and promoting the Wisconsin Department of Natural Resources with interpretive, scientific, historical, educational, and related visitor services at Wisconsin Interstate and Straight Lake State Parks.
Candlelight Night Fun
Nearly 500 people came out to experience winter fun by candlelight on February 7! People could choose to cross country ski or to hike four different routes at Interstate Park. Guests were also welcomed by warm fires and fun at the Ice Age Center which included a number of hot beverages, warm food, snacks and lively music provided by the Log Jammers!
A Wisconsin State Park System vehicle admission sticker is required on all motor vehicles stopping in state parks, forests and recreation areas.
Admission stickers can be purchased online or at most individual properties. (Remember, an annual pass is now valid for 12 months from the time of purchase.)
Celebrating 125 Years!
September 20, 2025 marked a special day for Interstate Park. Individuals from around the state and region came to help us celebrate this milestone!
The day was packed with history and programs throughout the park. Park visitors, DNR staff and Wisconsin Governor Tony Evers participated in the day’s festivities. Events included nature journaling, learning to rock climb, guided hikes on the Pothole Trail with the Traprock Chapter of the Ice Age Trail, History of the Wisconsin State Park System, the history of the Silverbrook Mansion, the Civilian Conservation Corp (CCC) and so much more!
The year’s not over, and there’s still more to come. Watch for information on our Annual Meeting and Fall Festival in October!
