The Great Divide Mountain Bike Route is known for its remoteness, and this section is no exception. While Park Lake has a national forest campsite, towns with resupply options and accommodations are often far apart. The nearest towns like Basin or Helena will offer services, but plan your water and food carefully for the stretches in between.
The best time to cycle this route is typically from late spring through early fall (June to September). During these months, snow has usually melted from higher elevations, and the weather is generally more favorable. Always check local weather forecasts and trail conditions before heading out, as mountain weather can be unpredictable.
