Wildlife Viewing Tips

🌅 Best Times of Day

Wildlife is most active during the "golden hours" - the first 2-3 hours after sunrise and the last 2-3 hours before sunset. Many animals rest during midday heat.

🔭 Essential Gear

Bring binoculars (8x42 or 10x42), a spotting scope for distant viewing, and a telephoto lens (300mm+) for photography. Dress in layers and bring water.

⚠️ Safety Distances

Maintain at least 75 feet from elk and deer, 120 feet from moose and bears. Never approach, feed, or follow wildlife. Use telephoto lenses for close-up photos.
