Visit the elk and bison viewing area early in the morning when the animals are most active near the fence lines.
Check the Saylorville Lake water levels on the Army Corps of Engineers website before planning water-based activities.
Bring binoculars, as the expansive park geography is prime for birdwatching, particularly for bald eagles in winter.
Do not attempt to feed the bison or elk, and avoid wandering off-trail in the prairie areas to prevent encounters with ticks or poison ivy.
The nature center and some camping loops have reduced operations during winter months.
Keep all pets on a leash in designated areas and maintain a safe distance from the elk and bison enclosures.
