While specific parking areas aren't detailed, this popular road cycling route around Castle Rock typically starts from various points along the loop. Look for public parking options in nearby towns like Castle Rock or Larkspur, or designated pull-offs that allow for safe vehicle parking. Always check local regulations before parking.
This loop is categorized as a 'hard road ride' and demands very good fitness. With over 3,000 feet (930 meters) of elevation gain across approximately 56.2 miles (90.5 km), it offers a significant workout with good rolling hills.
The route is generally described as having mostly well-paved surfaces. However, some longer routes in Douglas County might include short segments that are unpaved but still rideable for road bikes if they are well-packed. For instance, a portion of Ridge Road, which you might encounter after Lake Gulch Road, can be dirt but is typically well-packed.
You'll experience the diverse landscapes of Douglas County, featuring butte formations, rolling hills, and canyons. The area around Perry Park Road offers a 'mountain feel' with striking red rock formations and towering pine trees, alongside open grasslands. Keep an eye out for wildlife, especially on the Wildlife Viewing on South Perry Park Road highlight.
The best time to cycle this loop is generally during the warmer months, from late spring through early fall, when road conditions are optimal and the weather is pleasant. Winter cycling can be challenging due to snow and ice, especially in higher elevation sections.
As this is primarily a road cycling route, bringing dogs along for the ride is generally not recommended due to traffic and safety concerns. If you plan to stop at any parks or open spaces along the way, always check local leash laws and regulations for pets.
While this route is in the general vicinity of Pike National Forest, specific permits or entrance fees are typically not required for road cycling on public roads within Douglas County. However, if you venture into designated recreation areas or specific trailheads within the National Forest, always check the official Colorado.gov website or local forest service offices for any specific regulations or fees that might apply to certain areas.
Yes, the route intersects with several other paths. You'll find sections that overlap with the ADT - Colorado B - P - Seg 2, Colorado Front Range Trail, Plum Creek Parkway Trail, and the New Santa Fe Regional Trail, among others. These intersections could offer opportunities to extend or modify your ride.
Given its proximity to Castle Rock and Larkspur, you'll find various cafes, restaurants, and pubs in these towns. These are excellent spots to refuel and relax after completing your challenging ride.
Due to its 'hard' difficulty rating, significant elevation gain, and long distance (over 56 miles), this specific loop is generally not recommended for family cycling with young children or beginners. It's best suited for experienced road cyclists with very good fitness. For family-friendly options, look for dedicated paved trails or shorter, flatter routes in Douglas County.
For this challenging ride, be sure to bring plenty of water, nutrition, a repair kit (spare tube, pump, tire levers), appropriate cycling attire for varying weather conditions, sun protection, and a fully charged phone. Given the distance and elevation, a GPS device or a downloaded map is also highly recommended.
