This route was planned by komoot.
This route is considered difficult and requires very good fitness due to substantial climbs. It's known as a 'climber's ride' with significant elevation gain, making it a physical test for cyclists. While primarily paved, some sections, particularly near Pilot Hill, can be bumpy.
The route offers abundant and breathtaking scenery, including views of Folsom Lake, the American River, and the surrounding Sierra Nevada foothills. You'll pass by the Miner's Ravine Nature Reserve, the Auburn Triathlon Monument, and the Bernhard House & Wine Cellar museum. Other highlights include gliding over the Foresthill Bridge (California's highest bridge) and vistas of limestone outcroppings and Lake Clementine.
Yes, as this route is within the Folsom Lake State Recreation Area, there may be day-use fees or parking fees required. It's advisable to check the official California State Parks website (ca.gov) for the most current information on fees and regulations before your visit.
While the komoot tour starts near Auburn, there are various parking options around Folsom Lake State Recreation Area. Specific parking lots can be found near popular access points, but it's recommended to check local maps or the State Parks website for designated cyclist parking areas, especially in Auburn or Folsom.
The Folsom Lake loop can be enjoyed during many seasons, but spring and fall generally offer the most pleasant temperatures for cycling, avoiding the intense heat of summer. Winter can be cool and potentially wet, but still rideable on clear days. Always check the weather forecast before heading out.
This route is primarily designed for road cycling. While dogs are generally allowed in many parts of Folsom Lake State Recreation Area, they must be on a leash. However, bringing dogs along for a challenging road bike loop of this distance and difficulty is not typically recommended. If you plan to bring a dog, consider shorter, more leisurely trails in the area where they can be safely accommodated.
The Folsom Lake loop is known for its significant climbs. Key ascents include the Old Foresthill Road climb, which is about 4.8 km (3 miles) at a 5.9% average grade with steeper sections, and the strenuous Forest Hill Climb, a Category 3 climb over 3 miles. Descents can also be fast and technical, particularly the steep descent to the American River confluence with aggressive corners.
Yes, while the full Auburn loop is challenging, there are shorter options. You can find 50-mile loops with significant climbing or even 20-mile loops that are predominantly flatter with gentle hills. Shorter segments like the Johnny Cash Trail (10 miles) also offer views of Folsom Lake and the American River without the full intensity of the longer loop.
Yes, the route intersects with several other trails. Notable sections include parts of the 50 (California) trail, the Western States 100 Endurance Run route, and the American River Bike Trail. You may also encounter segments of the Wendell T Robie Trail and the Johnny Cash Trail.
Given the route's length and difficulty, it's essential to bring adequate water, nutrition, and repair supplies (spare tubes, pump, multi-tool). Sun protection, appropriate cycling attire, and a helmet are also crucial. Due to the significant elevation changes and potential for fast descents, ensure your bike is in excellent working condition.
The route passes through or near several towns, including Auburn, which offers various cafes, restaurants, and shops where you can refuel. Planning your stops in advance is recommended, especially for longer rides, to ensure you have access to amenities when needed.
