The Bottom Line

Hello, and thank you for visiting! You have arrived at the best place on the internet for avalanche, climbing and weather information for Mt Shasta!

We're glad you're here because climbing Mount Shasta is a serious endeavor, even if just off the interstate.  We can not stress enough the importance of proper preparation and a solid skill set to evaluate the terrain, weather and many other factors involved in staying safe climbing Mount Shasta.  Each year, climbers become lost, injured or killed while attempting to summit Mount Shasta.

The gate at Bunny Flat on the Everitt Memorial Highway is open to Panther Meadows, Old Ski Bowl, and South Gate Meadows trailheads. All wilderness trailheads are OPEN. PLEASE, LEAVE NO TRACE. Pack out your trash and human waste, stay on established trails, and leave Mount Shasta looking better than you found it!

Conditions Update

Currently, late-season conditions are in effect on Mount Shasta. Observations and updates of this advisory will be less frequent as we enter into the Fall season. Late season conditions mean that rockfall is likely, sun cups on any remaining snow are plentiful, and loose, rocky slopes are gaining size as snow melts. The lower half of the mountain is melted out, sun cups are large and thin strips of dirty, icy snow are intermingled with rocky terrain. Climbing conditions on the south and west sides have deteriorated and climbing the Avalanche Gulch, West Face, Casaval Ridge, Sargent’s Ridge and Green Butte Ridge routes is not recommended due to increased rockfall and almost no snow remaining.

The best late-season route for novice and intermediate climbers is the Clear Creek route. Some routes that start from the Brewer Creek TH are in decent shape like the Hotlum/Wintun ridge route. Routes from the Northgate TH are still in good shape such as the Hotlum/Bolam ridge. The north side routes are recommended for experienced climbers only. Watch for thin snow bridges on all glacier routes. Many variations and hazards exist to all these routes so know where you are going.

REQUIRED TO CLIMB MT SHASTA: Summit pass ($25 and required above 10,000 feet, even if you don't plan on going to the summit), wilderness permit (free) and human waste pack-out bag. All of these items are available for self-issue at all OPEN trailheads or the Mount Shasta/McCloud Ranger Stations and The Fifth Season store in downtown Mount Shasta. Annual passes are available from The 5th Season, 300 N. Mount Shasta Blvd. Due to COVID-19, the ranger stations are still closed.

Tips, Tricks and other info...!

All trailheads are currently open with full access. Some of the roads are rough but do not require 4wd. Kiosks at trailheads have self-issue permit stations and human waste packout bags are inside the restroom facilities. Upon your return, deposit full waste bags in trash receptacles.

Potable water is available at Horse Camp. This water is tested and good to go. Other reliable sources (but not tested) include the Clear Creek Springs, Northgate high camp, Ash Creek, Hotlum Hilton glacial tarn. One may find intermittent streams in some areas but otherwise plan on melting snow for water. Treating water is recommended.

Rockfall is a serious concern at this time. It will only increase as the summer presses on. You can be the best climber in the world and still get hit by a rock(s).

The vase majority of accidents happen in between Lake Helen and Redbanks on the Avalanche Gulch route. Most accidents are slips and falls, rockfall, or climbers getting lost. Pay attention, know how to self-arrest, wear a helmet, carry navigation tools. Note that climbing the Avalanche Gulch route is not advised due to late-season conditions.

Tie your tent down well! Wind will blow it away. 

Keep your food packed away. Animals such as ravens, squirrels, and pine martens will get into it.

Snowline on the mountain is about 11k feet. Dirt trails exist below. Please stay on trail.

Overall, we have had a dry winter on Mount Shasta. In terms of total precipitation for the winter, we are 50% of normal for the season and 45% for the year. February was the driest on record since 1948. 

It has been a funky season all things considered: a poor winter, the C-19 pandemic, and mixed spring weather. We always encourage people to challenge themselves with new (or familiar) adventures, but we ask that you please consider all things this year. As always, check the weather and be prepared. Slips/falls and climbers becoming lost on Mount Shasta continue to be the top search and rescue incidents, every year. These accidents are easily avoided by carrying proper navigation tools and knowing how to use your equipment. Further, be honest with your mountaineering knowledge, skills, and ability. If it doesn't feel right, it likely isn't.

The gate at Bunny Flat on the Everitt Memorial Highway is open to Panther Meadows, Old Ski Bowl, and South Gate Meadows trailheads. Running water is available at Horse Camp, and the bathrooms are open.  Make sure to bring extra fuel to melt snow for water if camping elsewhere. There are dry camping sites starting to melt out at Lake Helen. 

Camp cleanliness and overall mountain sanitation are very important to us and other climbers. When traveling in the wilderness always follow Leave No Trace principles.  Minimize your impact. Plan ahead and prepare. Travel and camp on durable surfaces. Depose of waste properly. Leave what you find. Always respect wildlife. 

Bunny Flat Trailhead

The Bunny Flat trailhead and Mount Shasta Wilderness are open.  It's not uncommon for Bunny Flat to host hundreds of people. Maintain social distance. Click HERE for California Coronavirus information. There is no water available at the trailhead. Bathrooms are provided and overnight camping is permitted. If you have a large RV, please park out of the way and downhill from the restrooms. 

Don't hesitate to give us a call for your specific questions at 530-926-9614. We're in the field a lot, but we'll call you back within a day or so.

Be Prepared!!

Our goal is to ensure you have a positive wilderness experience and come home in one piece! So,


Accidents and Hazards

Almost all the accidents on Mt. Shasta result from:

  • Slipping and falling with a failure to self-arrest
  • Glissading when the snow is too firm
  • Glissading with crampons on
  • Climbing into a whiteout
  • Being struck by early-season icefall or late season rockfall

With the right knowledge, skill, equipment, and decision making, all of these accidents can be easily prevented. Please, wear a helmet, and know how to use your ice axe and crampons any time of the year.

There is always the potential for thunderstorm activity during the summer months that can shroud the mountain in clouds, limiting visibility. Climbers becoming disoriented on the upper mountain in whiteout conditions, and subsequently descending the wrong route is not uncommon. These kinds of scenarios have resulted in many searches over the years. It should go without saying, but we will say it as a solid reminder: Check the weather before you go and more importantly, monitor the weather as you climb. DO NOT CLIMB INTO A WHITEOUT! Being caught on the mountain in any type of weather can compromise life and limb.

Many hazards exist in mountain terrain. Some of these include:

  • Ice and rockfall
  • Altitude
  • Extreme weather
  • Avalanches

Icefall and rockfall are possible year-round. It's a simple equation: as snow melts, rockfall increases. If rime ice is seen plastered to exposed rocks above, it will eventually flake off and fall onto climbers. Wear a helmet and keep your eyes up slope as you climb. Pay attention to other climbers: rockfall is often caused by climbers resting in melted out areas and accidentally dislodging rocks onto slopes and climbers below. Be careful not to kick rocks down onto others.

At a height of 14,179 feet, Mount Shasta is a high altitude peak. It is common for climbers to experience acute mountain sickness (AMS) with signs and symptoms of nausea, headache, and lightheadedness. Despite being a common condition, AMS should not be taken lightly. It can quickly develop into the much more serious, and potentially deadly pulmonary or cerebral edema. Stop and take a break. If symptoms do not improve, your only choice is to descend!

Mt Shasta is a 14, 179-foot volcano with steep slopes, avalanches, glaciers, rockfall, altitude, and extreme weather. Some may feel like Mt Shasta is "safe" due to it's proximity to Interstate 5 and it's "easy" climbing objective connotation. This is false. One should still expect cold, winter-like conditions at any time of year. Have the appropriate gear AND skill level. Mountaineering is dangerous and climbers must be able to constantly evaluate the terrain, weather, and many other factors in order to have a safe trip. One should also not expect immediate rescue. Many factors can prolong rescues. Thus, it is necessary, no matter what mountain of the world, that you be prepared.

Mountain Weather

Check the WEATHER FORECAST before coming up onto Mt. Shasta! Our site's main menu hosts numerous resources on the weather. Researching the mountain weather should be an important part of your trip planning.

Clouds and Precipitation: While you may encounter fair weather at lower elevations, cloud caps can form up high. Never climb into a whiteout as many climbers have become lost or died in similar conditions. Many routes from all aspects of Mt. Shasta converge on the upper mountain (>12,500 feet). During limited visibility conditions, climbers have descended the wrong side of the mountain. Keep an eye to the sky as you climb, turning around if clouds begin to build on or near the mountain.

Lightning: Mt. Shasta is a 14,000-foot lightning rod and is frequently hit by lightning (usually in summer and fall months), so don't push your luck with building thunderheads.

Wind: Winds can reach over 100 mph at tree line (8,000 ft) and much higher in the alpine region. Winds of 40 mph can knock you off balance. Winds of 60-70 mph can force you to crawl. Hurricane strength winds (>74 mph) can make it nearly impossible to stand and will destroy well-anchored tents. The strongest winds occur with big pressure and temperature gradients in the atmosphere and tend to occur in front of, and behind storms. The lowest winds occur when the center of high pressure is over the Mt Shasta area. Take this seriously as wind has resulted in searches, injuries, and fatalities.

Tips & Notes

Climb early and descend early. This limits exposure to inclement weather (afternoon buildup of clouds is common), and allows plenty of time to descend before dark, and also allows a rescue effort to ensue before dark in the event one gets injured or lost.

Get an alpine start (2-5 am) and have a turn around time of 12 to 1 pm. Proper equipment, clothing, and training are a must. Helmets are recommended always and expect rock and ice fall at all times.

Bring extra warm gear (like a down jacket, balaclava, and extra gloves) in all seasons as climbers often develop superficial frostbite during strong winds. The wind chill temperature near the summit in winter and spring can be well below zero.

Anchor your tent well wherever you camp. Tents can and do blow away frequently. Do not plan to camp above treeline if you do not have anchor lines for your tent.

Solo climbing is not recommended. Traveling with an experienced group is a good idea, and remember - do not split up the group!

The routes on the north and east sides are not recommended for unguided novices; glacier travel and route finding skills are prerequisites.

Get avalanche training and know how to use your transceiver, shovel, and probe in the winter and spring.

Mountain Rescue

Do not expect to be rescued. Rather, prevent rescues from happening in the first place, and be prepared to handle rescues within your climbing party should something happen. Nature sets its own terms and YOU must judge how much risk you are willing to accept.

When to Climb

The BEST time to climb Mt. Shasta is usually from late May to mid-July on the south and west sides of the mountain when summer days are longer and the weather is generally stable. However, in dry years, the thin snowpack creates the best climbing conditions in April, May and early June. When the snow melts, you are left with 7,000 feet of scree, talus, and boulders. In heavy snow years, the climbing season extends to August or September. There is NO trail to the summit. Climbing is much safer and fun on consolidated snow.

A winter climb of Mt. Shasta is possible, but it is more difficult and dangerous: extreme weather, short days, avalanches, falling ice and potential post-holing increase the difficulty and danger on all routes. If you choose to travel in the backcountry during the winter and spring, you need to have the proper equipment and training to stay safe. An avalanche beacon, shovel, and probe and the ability to identify avalanche terrain and snow stability are e. A climb of Shasta should not be taken lightly.

Every year, many climbers become lost, injured or killed while attempting Mt. Shasta. Many of these accidents could have been prevented with a little bit of pre-planning and training. Full winter conditions exist currently and YOU need to come prepared.

What to Bring

  • MANDATORY: wilderness permit, summit pass, human waste pack-out bags.
  • THE TEN ESSENTIALS: map and compass, sunglasses and sunscreen, extra food and water, extra clothing, headlamp/flashlight, first aid kit, matches/lighter, stove, knife/multi-tool, bivy sack

Wilderness permits, summit passes, and pack-out bags are currently available at the Mt. Shasta and McCloud Ranger Stations for self-issue and inside the buildings (maps available) during business hours. The only trailheads open currently are Bunny Flat and Northgate. The remainder of the trailheads are closed. You may still access the closed trailheads and the bathrooms are open/packout bags available, but you must get your summit pass ($25) and wilderness permit from either ranger station. Annual passes ($30) are only available at the ranger stations and The Fifth Season in Mt Shasta. The Mt. Shasta and McCloud Ranger Stations are open Monday through Friday from 8 to 4:30 PM. Check our climbing regulations for more details.

Using common sense and carrying the TEN essentials keep you and your party out of search and rescue statistics. Wear a helmet, and know how to use your ice axe and crampons. Be prepared and pay attention. The mountain has extreme weather changes.

Winter and Spring months usually see periods of heightened avalanche danger, though this danger could exist in the summer months under the right circumstances. Research the weather and avalanche danger while planning your trip. Have your climbing party bring avalanche beacons, probes, and shovels armed with proficient skills in their use. Know how to identify avalanche terrain and evaluate snowpack stability.

Horse Camp

The bathrooms are CLOSED at Horse Camp. The spring is dry and buried at this time. It is recommended that Horse Camp visitors come prepared with their own water. The Horse Camp cabin and the surrounding property are owned and managed by the Sierra Club Foundation. The cabin is open year-round and all are welcome, however, one cannot sleep inside the cabin except in emergencies. Make sure you close the door when you leave. If you plan on camping at Horse Camp, a nominal $3 bivy/$5 tent fee is asked. Lastly, the Sierra Club Foundation manages its property under the Mt. Shasta Wilderness rules - that means dogs are not allowed on their property either. Please respect the rules. Thanks!
