Clouds Rest Trail in California is a hard-rated route that demands respect — 12.0 miles with significant elevation change up to 9,926 ft. Our daily Suitability Score helps you pick the window with the best conditions, but this trail requires self-sufficiency and solid navigation skills.
Today’s Conditions at a Glance
High-Elevation Considerations
Summit temperatures can feel 9°F cooler than the trailhead (roughly 3.5°F per 1,000 ft gained). Above 8,000 ft, watch for altitude sickness symptoms: headache, nausea, and shortness of breath. Descend if symptoms worsen.
- Start early to avoid afternoon storms on exposed ridges
- Pack insulating layers even in summer
- Carry extra water — dehydration accelerates at altitude
Long-Distance Planning
At 12.0 miles, this is a full-day commitment. Budget 7 hours on trail including breaks. Identify a turnaround time before you start — don’t out-hike your daylight window.
- Pack calorie-dense snacks (500+ kcal beyond normal lunch)
- Trekking poles reduce knee strain on long descents
- Share your itinerary with someone not on the hike
Seasonal Guide
- Spring: Spring (California): Snow may linger above 7,926 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 9,926 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 6,926 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
- Insulating mid-layer and waterproof shell
- Trekking poles and headlamp
