Runner Notes

This is not recommended for trail runners.


Starting from the Cisneros Trailhead across from Spruce and Ponderosa group campgrounds, follow the Cisneros Trail as it makes a steady climb up steep terrain. Eventually, the trail reaches a junction with the Marion Mine Route. Use the Trail Run Project mobile app to make sure you don't miss it! Make a right here and follow this unmaintained route up Amethyst Creek to reach Marion Mine.

Along the way, you'll come across a cabin by a creek. That was an old cabin used by someone in the mining era, however as you can see, someone purchased it. It is now in good shape and inhabited. The trail will be pretty steep for most of the run, but it is well worth it. If you come in the right season, there will be lots of wild raspberries and strawberries growing just off the trail.

The trail begins at the Cisneros Trailhead in Lake Isabel Recreation Area. If you don't feel like camping there are nice cabins at The Pine Lodge (, and you can get a good bite to eat at the Lodge (not to be confused with the cabins) across the street from San Isabel Lake.

Flora & Fauna

Aspens, raspberries, strawberries, grass, mountain lions, bears, bobcats, marmot, deer, and raccoons can be found here.
