Great Marsh Trail (South)

Q: How muddy are we talking?

Very. Even dry conditions = squishy sections. Post-rain = slop. Waterproof boots are mandatory, not optional.

Q: How close are the birds?

Binocular-close from the observation deck. Herons, cranes, waterfowl at arm's reach. Peak diversity in spring and fall migration.

Q: Is this kid-friendly?

Yes. Short distance, flat terrain, big payoff at the observation deck. Tick prevention required—dress long or apply repellent.

Q: What's the biggest hazard?

Ticks year-round. Use repellent, wear light colors so you spot them, and do a full-body check afterward. Poison ivy on trail edges—don't brush it.
