Henrys Lake State Park to be OPEN and staffed this winter! Henrys Lake State Park will remain open and accessible to the public this winter. The park will have full-time and seasonal staffing presence on-site, enabling the park to maintain the roadways to and within the property. Although the park can receive heavy snowfall and windy conditions, the park has obtained heavy equipment to keep the roads and parking lots plowed and blown for visitors to access the park. Approximately a dozen dry RV sites will be available to rent, along with 3 heated cabins for rent. Please visit the Reservations section on the main IDPR webpage to see availability. As a reminder, there will not be water available for use in the park. Henrys Lake is a perfect location to ice fish in winter, so all are welcomed to come try their luck. The regular $7 MVEF is applicable to visitors entering the park, and can be paid at the entrance kiosk. The main parking lot next to the Lake will be open and available for parking. Dump Station Remains Closed Due to problems with the drain field, the Dump Station at Henrys Lake State Park will remain closed for the 2025/2026 season. Any updates to service availability…
