How this list is ranked
Rating = the square root of 2 x elevation gain (ft) x distance (miles), the gain-and-distance formula Shenandoah National Park publishes for its own trails. Bands: under 50 easiest, 50 to 100 moderate, 100 to 150 moderately strenuous, 150 to 200 strenuous, 200 and over very strenuous.
This list: band strenuous (150 to 200) or very strenuous (200 and over), 3 to 30 miles, at least 1,500 ft of gain, ordered by rating desc, gain per mile desc, capped at 25. The rating column is computed from the miles and gain printed in the same row, the numbers each trail page uses, so every row can be checked from the row itself. The rating says nothing about exposure, scrambling, altitude or conditions.
Only trails with a full page count, so "Bulgaria" here means the 85 trails in Bulgaria in our dataset, not every trail in Bulgaria.
Each trail page shows the full elevation profile behind these numbers and the same data drawn as a topographic print, made to order. Start with khiza Mechit to Rila Monastery.
