How to pick a trail in Key Biscayne
- Match the surface to your legs. Key Biscayne gives you a choice: 2 boardwalk and 1 mixed. Asphalt and concrete are fast, predictable and runnable year-round but the least forgiving; crushed limestone and dirt take the sting out of high mileage; boardwalk is flat and scenic but slick in the wet. If your shins or knees are complaining, the fix that actually works is varying the surface you run on rather than chasing one "best" one. More boardwalk trails →
- Loop or out-and-back? A loop finishes back at the car with no backtracking; on an out-and-back you simply turn round at half your distance.
- Check the hours before a 6am run. Plenty of trails sit inside parks that gate at dusk and don't unlock until well after sunrise, so a trail that's perfect at lunchtime can be locked at 6am. 4 of the 7 listings carry posted opening hours — worth a look before you set an alarm. 2 are lit, which is what you want for winter evenings.
- Long run? Check water and restrooms first. 5 have trailhead parking, 4 have restrooms, and 1 has a water fountain in Key Biscayne. Anything over an hour and those stop being nice-to-haves — and in summer, shade counts double.
- The small things that decide it. 3 that runners describe as quiet, 1 dog-friendly, and 2 smooth and wide enough for a stroller or a wheelchair. Busy or quiet isn't a good-or-bad thing here: a busy path is the safer choice for a solo run at dawn, a quiet one is better for intervals.
