Embark on the Old and New San Juan Trail Loop, a challenging jogging route that spans 17.7 miles (28.6 km) through varied terrain. You'll encounter rocky sections that demand careful footing, but your effort will be rewarded with expansive views of the surrounding hills and mountains. Imagine jogging alongside a peaceful creek, shaded by ancient oaks, before the trail opens up to more exposed areas. This difficult route involves a significant elevation gain of 3118 feet (950 metres), making it a substantial workout. Plan for a duration of approximately 3 hours and 54 minutes to complete this demanding loop.

The trail is easily accessible, located conveniently off Ortega Highway, also known as Highway 74. While the route is generally well-maintained, be aware that certain sections, especially in the northern part, offer no shade, so prepare accordingly with sun protection and plenty of water. This loop is a great option if you enjoy jogging with your canine companion, as it is dog-friendly. Consider starting early in the morning to avoid the midday sun, particularly during warmer months.

This route offers a dynamic experience, transitioning between sheltered areas and open stretches. After a good rain, you might even spot a seasonal waterfall, adding a unique visual element to your jog. The mix of terrain and scenery, from shaded creek beds to panoramic mountain vistas, ensures that your focus remains engaged throughout the journey. It's a fantastic way to experience the diverse landscapes of the Cleveland National Forest.
