Finding the most efficient route in a trail network

Hello, I’m looking for help with a mapping question.


There’s a network of about 150 official trails in the Great Smoky Mountains National Park (GSMNP) totaling about 790 miles. To hike all these trails (ending at a trail head), one has to repeat some mileage. There’s a guidebook out there that provides a 1060-mile plan for completion (with hikes limited to 20-miles or less). There’s also a hiker who’s reportedly completed all the trails by hiking only 924 miles.


Here’s the question: is there a way to calculate the most efficient route for completing all unique 790 miles of trails in GSMNP using ArcGIS (or other program)?


If so, any tips to help me get started would be appreciated!
