Algonquin Provincial Park is accessible year-round. Drivers can pass through the park along Hwy 60; you must pay the day-use fee ($17 per vehicle) if you plan to stop and look around. The Hwy 60 corridor has limited cell-phone coverage in the park, and for several kilometers on each side. There are payphones.
Each kilometer of Hwy 60 within the park is tagged, starting at the West Gate (known as 'Km 0') and terminating at the East Gate ('Km 56'). Outfitters and accommodations use these markers when giving directions.
The Algonquin Visitors Centre has an information desk, bookstore and wi-fi.
