- •The first releases of the season are June 5 and June 13 — the season itself starts June 15
- •Check TripCheck.com before you commit: several of these trailheads sit behind Oregon 242 or the Cascade Lakes Highway, which do not open until mid or late June
- •A PDF on your phone is accepted, so you do not need a printer

Duration
Day use — the permit covers one calendar day at this trailhead
Highlights
- •A permit tied to one trailhead and one calendar day, checked at the trailhead
- •Permits released at 7:00 a.m. Pacific on a 10-day and a 2-day rolling window — nothing sold further out
- •A digital PDF on a phone is accepted as proof
- •No restrooms inside the wilderness; trailhead facilities vary and may include parking, bathrooms, picnic tables and stock hitching posts
- •Cross-country travel skills needed for many of the high lakes and peaks — the Forest Service says so outright
Best Time to Visit
The permit season is June 15 to October 15 and that is close to the whole usable window. Trails often hold snow into late June, so late July through September is the reliable stretch. September is the quietest month inside the season, with the caveat that the higher trailheads can get their first snow before the season formally ends.
Hazards & Considerations
- !Snow into late June on the high trails, and on some approaches later than that
- !Burned-area travel. The Forest Service is explicit that risk is higher in burned areas — falling trees and unstable ground, with no warning
- !Afternoon thunderstorms over open lava and alpine terrain with no shelter
- !No water at most trailheads and no restrooms anywhere inside the wilderness

Best For
Day hikers who can plan around a 7:00 a.m. release window and a road that may not be open when they want it.
Recommended Experience
None beyond normal day-hiking judgement, though the Forest Service notes that cross-country travel skills are needed to reach many of the high lakes and peaks from these trailheads.
Not Recommended For
Anyone hoping to book a summer Saturday months out — the system deliberately does not sell that far ahead.
About This Permit
Three Sisters - Crater Ditch Trailhead is one of the trailheads inside Oregon's Central Cascades Wilderness Permit area. The Forest Service requires a day-use permit at 19 trailheads across the Three Sisters Wilderness and its two neighbours, and the season runs June 15 through October 15.
Day-use permits are released daily at 7:00 a.m. Pacific in a rolling 10-day and 2-day window ahead of your hiking date — the first releases of the year land on June 5 and June 13. There is no full-season advance sale, so the entire booking strategy for a day hike here is knowing which morning your date opens.
This is an alternative trailhead to the Broken Top trailhead Broken Top and Crater Ditch are named specifically by the Forest Service: they may not be reachable by vehicle until late July or early August, access depends on Forest Service Roads 4600-370 and 4600-380, and those roads require 4WD and high clearance. Permits for early-season entry dates may not be released at all depending on snowpack.
The Experience
Why It Matters
Oregon put this system in place in 2020 because the Mt. Jefferson, Mt. Washington and Three Sisters wildernesses sit within easy reach of Portland, Salem, Eugene and Bend, and the trailheads nearest those cities were being loved into the ground. The permit is not a fee gate; it is a headcount at the door of a very short summer season.
The Route
This is an alternative trailhead to the Broken Top trailhead
The permit does not route you. It admits you to the wilderness through this trailhead on this date, and where you go after that is your business — as long as you are out the same day, because a day-use permit does not cover an overnight and an overnight permit does not cover day use.
The Feeling
The country here is young volcanic ground with old forest wrapped around it — obsidian, cinder, wildflower meadow and water so clear it reads as empty. The snow leaves late and comes back early, so the whole thing is compressed into the same four months everybody else wants.

Getting There
Broken Top and Crater Ditch are named specifically by the Forest Service: they may not be reachable by vehicle until late July or early August, access depends on Forest Service Roads 4600-370 and 4600-380, and those roads require 4WD and high clearance. Permits for early-season entry dates may not be released at all depending on snowpack.

- •One reservation can hold up to 12 permits per day if the quota is there, and every member of the party needs their own printed or PDF copy

Gear Checklist
Required

- A detailed map; the Forest Service asks hikers and equestrians to carry one and to check conditions in advance
- Sun protection for open lava and alpine ground
Recommended
- Traction and gaiters before mid-July on the higher trails
- A stove rather than a fire — campfires are banned above 5,700 feet anyway

Crater Ditch FAQ
Do I need a permit to day hike from Crater Ditch Trailhead?
Yes, between June 15 and October 15. The Forest Service requires a Central Cascades Wilderness day-use permit at 19 trailheads across the Mt. Jefferson, Mt. Washington and Three Sisters wildernesses, and this is one of them. The permit is per person, valid only for the date and trailhead printed on it, and the group leader has to be present. Outside June 15 to October 15 no permit is required.
When do Central Cascades day-use permits go on sale?
Daily, at 7:00 a.m. Pacific, in a rolling 10-day and 2-day window ahead of the hiking date. The first releases of each season are June 5 and June 13. There are no full-season advance sales, which is why there is no way to lock in a summer weekend months out.
What is the group size limit for a Central Cascades permit?
One reservation can secure up to 12 permits per day if the quota allows, and overnight quota is written the same way — groups can be up to 12 people. Everyone needs their own copy of the day-use permit, and the named person on the reservation must be with the group at all times.
Does a Central Cascades overnight permit cover day use?
No. The Forest Service states plainly that overnight permits are not intended for day use. It works the other way round, though: if you hold an overnight permit you do not also need a day-use permit.
Are there exceptions to the Central Cascades permit requirement?
Two. Long-distance travellers on the Pacific Crest Trail holding a valid PCTA 500-mile permit are exempt, with additional camping restrictions. So are hunters holding a valid Oregon Department of Fish and Wildlife deer, elk or mountain goat tag during the hunting season.

Golden Hour
Early morning, before the afternoon build-up. The high country here clouds over fast in summer.
Best Light
Late September, when the air clears out and the low sun rakes across the lava and cinder.
Beat the Crowds
The quota does the heavy lifting. Beyond that, weekdays and the first week of the season after snow clears are reliably quieter than a July Saturday.
Classic Shots
- 📍Volcanic ground and old forest in the same frame — the defining contrast of this wilderness
- 📍Alpine meadow in full wildflower, mid-July
- 📍A high lake at first light with the peaks behind it
- 📍The trailhead permit board, which is the honest picture of how this system actually works
Can't Get a Crater Ditch Permit?
Consider these alternatives if your preferred dates aren't available.
Central Cascades Wilderness Overnight Permit
Same AreaThe overnight permit covers all overnight use of the same three wildernesses, and a day-use permit is not needed in addition to it. Quota is by group, per entry date and entry trailhead.
Permit required
Tradeoffs
Different release schedule — roughly 40% of each trailhead's daily quota opens on the first Tuesday in April and the remaining 60% seven days out. Overnight permits are not valid for day use.
A Central Cascades trailhead with no day-use requirement
Easier AlternativeOnly 19 trailheads in the three wildernesses require a day-use permit. Plenty of others do not, and they reach the same country by a longer approach.
No permit needed
Tradeoffs
More miles for the same lakes and ridgelines, and you give up the guaranteed parking that comes with a quota trailhead.
A weekday or late-September date at this trailhead
Same AreaThe same permit, the same trailhead, on a date the release window is not being fought over.
Permit required
Tradeoffs
Colder and shorter days in late September, and the higher approaches can take an early snow.
