The hiking trails on St. John are rated by degree of difficulty. There are three ratings: easy, “moderate,” and “strenuous.” Most of the trails are rated strenuous, and we haven’t encountered an “easy” trail yet. I think all “easy” trails may involve boardwalks and be wheelchair accessible.
What distinguishes “moderate” and “strenuous ” is more elusive. The trail shown above is rated strenuous, and the trail pictured below is moderate. So far as I can tell, they both have more than their fair share of rocks, tree roots, and constant inclines. Perhaps moderate trail don’t exceed 45-degree inclines and only have so many rocks and roots per square foot.
“Strenuous”? Well, sometimes you won’t even see a recognizable trail, be prepared to huff and puff on the unending upward switchbacks, and on the way down bring a little mountain goat with you.
