Today’s Conditions at a Glance
⚠️ Slot Canyon Flash Flood Risk
Do not enter slot canyons if rain is forecast within 50 miles. Flash floods can arrive with no visible rain at the trailhead. Check our 7-day rain forecast and local park alerts before committing.
Desert Hiking Safety
Desert trails demand strict heat management. Plan to finish before 10 AM in summer. Carry at least 4.5 L of water (1.2 gal) for this 9.0-mile route.
- Wear sun protection: hat, sunscreen, light long sleeves
- Electrolyte replacement is essential in heat
- Watch for heat exhaustion: dizziness, cramping, confusion
Seasonal Guide
- Spring: Spring (Utah): Snow may linger above 6,000 ft through May. Muddy lower sections are common. Layers essential — mornings can be near freezing.
- Summer: Summer: Start before 8 AM to beat heat and afternoon thunderstorms. Afternoon temps at 5,200 ft can still be comfortable, but exposed sections get hot quickly. Lightning risk peaks on exposed ridges after noon.
- Fall: Fall: Often the best hiking season — stable weather, fewer crowds. Shorter days mean plan turnaround times carefully after September.
- Winter: Winter: Limited daylight and potential snow/ice above 5,000 ft. Check our daily score; many trails remain accessible with traction devices.
What to Pack
- Sturdy hiking boots with ankle support
- 2+ liters of water (more in heat or for long routes)
- Snacks and electrolytes
- Sunscreen, hat, and sunglasses
- First-aid kit and whistle
- Fully charged phone + offline map backup
- Electrolyte tablets and sun-protective clothing
