Johnny Horn Trail
What to Expect
Safety Advisory
There is zero shade on the upper sections and tropical sun at this latitude is no joke — heat exhaustion is a real risk if you start after mid-morning without adequate water and sun protection.
The trail surface includes loose rock and uneven stone steps from historic ruins — ankle-rolling terrain that gets treacherous when wet from rain showers that blow in with little warning.

Pro Tips
Start early — by 7 AM if possible. The trail faces east and loses shade fast once you clear the tree line, and afternoon tropical showers can make the rocky sections slippery.
Take the left spur at the first hilltop junction even if you're tired. It adds only five minutes but delivers the best 360-degree viewpoint on the entire Leinster Bay side of St. John.
Combine this with snorkeling at Waterlemon Cay afterward — the trailhead beach is the launch point, and cooling off in the water after that climb feels like a religious experience.
