Permits & Passes
Mount Shasta has a straightforward two-permit system — a free overnight wilderness permit and a paid summit pass. Neither requires advance booking or a lottery, but both are required and part of responsible climbing on this mountain.
Required for all climbers traveling above 10,000 ft on Mount Shasta. This is a paid permit enforced by the Forest Service and purchased at ranger stations or self-issue kiosks at major trailheads when staffed.
- Valid for up to 3 consecutive days from the date of purchase
- Applies to everyone in your party — one pass per person
- Carry your pass with you on the mountain; rangers do check
- Purchase at the Mount Shasta Ranger District office or at self-issue stations at Bunny Flat (when available)
- Verify current payment methods accepted before arriving — cash requirements can change
Required for all overnight camping within the Mt. Shasta Wilderness boundary. Day-use climbers who ascend and descend in a single day do not need the wilderness permit, but summit pass requirements still apply above 10,000 ft.
- Self-issued at trailhead permit boxes and the ranger district office
- No advance booking or quota — fill out the form at the trailhead before entering the wilderness
- Carry a copy with you during your climb
- Human waste pack-out requirements apply within the wilderness — wag bags are required and available at the trailhead
The absence of a lottery or quota system makes Shasta logistics simpler than many comparable peaks. However, this also means the mountain can be crowded on popular weekends, particularly on Avalanche Gulch in peak spring season. Early-week climbs often offer a better experience — and better snow conditions — than peak-weekend attempts.
Wag bags are required for all solid human waste above the tree line within the Mt. Shasta Wilderness. This is a strict regulation, not a recommendation. Wag bags are available at the Bunny Flat trailhead and the ranger station. Plan for one per person per day above tree line. Failure to comply can result in fines.
Trailheads & Access
Mount Shasta’s trailhead situation is more variable than most climbers expect. In recent seasons, several alternative trailheads have been closed due to road damage, seasonal restrictions, or other access issues — concentrating most climbing traffic on the south-side Bunny Flat corridor. Confirm current access status before your trip.
In 2025, only Bunny Flat and Sand Flat were confirmed open among major Shasta trailheads. Clear Creek, Brewer Creek, North Gate, and Old Ski Bowl were all closed, and the Bolam road was washed out. This situation can shift year to year. Call the Shasta-Trinity National Forest ranger district or check their conditions page before finalizing your logistics.
Camping & High Camp
Most Shasta climbers use a one-night or two-night camp strategy. The most common camps on the standard Avalanche Gulch route are Horse Camp and Helen Lake — each serving a different style of ascent.
| Camp | Elevation | Route | Character | Notes |
|---|---|---|---|---|
| Horse Camp | 7,900 ft | Avalanche Gulch | Lower camp; hut on site | Sierra Club hut with caretaker in season; water source; good for acclimatization nights or slower two-day plans |
| Helen Lake | ~10,400 ft | Avalanche Gulch | Standard high camp | Most popular high camp for summit attempts; flat tent platforms in snow; no shelter; exposed to wind; wag bag use required |
| Above Helen Lake | 10,400–12,000 ft | Avalanche Gulch | Not recommended for camping | Above the established camp zone; rockfall exposure increases significantly; no flat ground; rangers may discourage camping here |
Camping Regulations to Know
- Wag bags required for all solid waste above tree line — do not bury or leave waste on the mountain
- No campfires above tree line — stoves only
- Camp on snow where possible to minimize impact on fragile volcanic soil
- Do not camp at the Helen Lake outlet or in heavily impacted flat zones when snow-free alternatives exist
- Leave No Trace principles apply throughout the wilderness — pack out all trash, including food scraps
If you have flexibility, spending night one at Horse Camp (7,900 ft) and moving up to Helen Lake on day two before a midnight summit push gives better acclimatization than going straight to Helen Lake on day one. Climbers arriving from sea level — especially those flying in — benefit meaningfully from this slower approach.
Pre-Climb Logistics Checklist
Use this sequence to organize the non-technical side of your Shasta climb. Getting logistics right before you leave for the trailhead removes a significant source of stress from summit day.
-
1
Check Current Conditions & Trailhead Status
Call or check online with the Shasta-Trinity National Forest ranger district at least one week before your climb. Confirm which trailheads are open, whether any road closures apply to your planned approach, and whether any special regulations are in effect for the season.
-
2
Purchase Your Summit Pass
The $25 summit pass is required above 10,000 ft. Pick it up at the Mount Shasta Ranger District office in the town of Mount Shasta (204 West Alma Street) during business hours, or at the self-issue station at Bunny Flat if staffed. Confirm current payment methods accepted before arriving.
-
3
Self-Issue Your Wilderness Permit
For overnight climbs, fill out a free wilderness permit at the trailhead permit box before entering the wilderness. This is a 2-minute process — do not skip it. Carry the permit with you throughout your climb.
-
4
Pick Up Wag Bags
Collect enough wag bags for every person in your party for every night above tree line — minimum one per person per day. Available free at the Bunny Flat trailhead and the ranger district office. Running out on the mountain is not an acceptable outcome.
-
5
File a Climb Plan
Leave a detailed climb plan — route, camp locations, summit day schedule, and expected return time — with a trusted person who is not on the climb. Shasta rescues have been triggered by teams that did not communicate their plans. A written plan costs nothing and matters enormously if something goes wrong.
-
6
Check the Avalanche Forecast
The Mount Shasta Avalanche Center publishes current avalanche forecasts for the mountain. Review the forecast before departure — especially for spring climbs when new snow, rain-on-snow events, and warming cycles can significantly affect avalanche hazard on Avalanche Gulch and other south-side terrain.
