The best time to hike the Enchantments Traverse is mid-July to mid-October 2026, once Aasgard Pass clears of snow. Late July through August offers the warmest, most reliable conditions, while the last week of September and first week of October bring the famous golden larches - the most popular but most crowded window for this 18-mile (29 km) Washington route.
When is the Enchantments Traverse snow-free?
The Enchantments Traverse climbs to 7,800 ft (2,377 m) at Aasgard Pass, and that steep, north-facing slope is the last to lose its snow. In an average year the pass becomes safely snow-free without an ice axe by mid-to-late July; after a heavy winter it can hold snow into early August. For 2026, a near-average Cascade snowpack pointed to a normal mid-July opening. Before that, the descent of Aasgard requires self-arrest skills and traction. Check the route profile on the Enchantments Traverse guide.
Month-by-month on the Enchantments Traverse
| Period | Conditions | Verdict |
|---|---|---|
| Jun-early Jul | Snow on Aasgard, axe needed | Mountaineering skills only |
| Late Jul-Aug | Warm, dry, wildflowers | Best for conditions |
| Mid-late Sep | Cool, larches turning | Excellent shoulder |
| Late Sep-early Oct | Peak golden larches, crowds | Most scenic, most busy |
| Mid-Oct+ | First snows, short days | Closing window |
Summer: the most reliable conditions
Late July and August deliver the warmest, driest weather of the year, with daytime highs of 70-80 F (21-27 C) in the valleys and comfortable 50-60 F (10-16 C) in the Core. Wildflowers peak, the granite is dry and grippy, and the long days give a comfortable margin for the 18-mile (29 km) push. The trade-off is heat on the exposed lower Snow Lakes descent. For a single-day traverse in summer, a ventilated running vest like the Salomon ADV Skin 12 keeps you cool and fast.
Larch season: late September to early October
The reason most hikers dream of the Enchantments is larch season. From roughly 25 September to 8 October, the alpine larches of the Core turn brilliant gold against the granite and turquoise lakes. It is the most photographed window in the Washington Cascades - and the most contested, with day-hike trailheads at Stuart Lake filling before 5 am. Nights now drop near freezing, and a sudden early snow is possible. Carry warm layers and start early. An overnight in larch season needs a permit and a light pack such as the Zpacks Arc Scout 37L.
The permit calendar - plan in February 2026
Timing the hike is only half the battle; timing the permit application is the other half. Overnight Enchantment permits are drawn in an annual lottery on recreation.gov, with the application window opening in mid-February and closing in early March 2026, and results in late March. Core Zone success rates run below 5%, and larch-season dates are the hardest to win. Day hikers skip the lottery but must complete the full traverse in one day. Forest and trail status is posted by the Okanogan-Wenatchee National Forest.
Putting it together
If you want guaranteed conditions and can hike a long day, aim for August. If you want the iconic gold and can plan a year ahead, target the late-September larch window and apply for the lottery in February. Either way, read the Enchantments difficulty guide and the Enchantments packing list before you go, and consider the contrasting season of the Uinta Highline Trail if you also want a Utah objective. The Pacific Crest Trail through Washington shares the same prime months.
Crowds and how to avoid them
The Enchantments are a victim of their own beauty, and the season dictates how busy they feel. In peak larch season the day-hike crowds are intense: the Stuart Lake trailhead parking lot fills before 5 am on late-September weekends, and a steady file of hikers moves over Aasgard Pass all morning. To find space, hike midweek, start before dawn, or shift your dates to early August when the scenery is still superb and the trail far quieter. Weekday August trips can feel genuinely remote despite the route's fame. Moving efficiently with a light vest such as the Salomon ADV Skin 20 lets you stay ahead of the pack on the climb and reach the Core Zone before the crowds catch up.
Weather and storm risk by season
Cascade weather is the wild card. Summer brings the most stable conditions, but afternoon thunderstorms can still build over the high granite, and the exposed Core Zone offers little shelter. By late September and October, Pacific fronts roll in more frequently, bringing rain at the valley trailheads and the first snow up high - an early storm during larch season can coat Aasgard Pass overnight. Always carry a packable rain shell and insulation, even on a warm forecast, and pack them in a quick-access fastpack like the Patagonia Ascensionist 35L for overnights or the Zpacks Arc Scout 37L for fast trips. Check the mountain forecast within 24 hours of your start and be willing to turn around at Colchuck Lake if Aasgard is socked in - the pass is treacherous in cloud and fresh snow.
Day hike or overnight: timing both options
The season also shapes whether to attempt the traverse in a day or apply for an overnight permit. In long-daylight July and August, a strong party can complete the 18-mile (29 km) traverse comfortably between dawn and dusk, making the permit-free day-hike option attractive. By October, daylight shrinks to about 11 hours, and an unhurried overnight - if you hold a permit - lets you avoid finishing the rocky Snow Lakes descent in the dark. Either way, carry a headlamp, because a slower-than-planned Aasgard climb can push your finish past sunset even in summer.
Frequently Asked Questions
When is the best time to see larches in the Enchantments?
Golden larches in the Enchantments peak from about 25 September to 8 October, with exact timing shifting a few days each year based on weather. The Core Zone, the highest and most scenic basin, usually colours first. This is the single most popular and most crowded window of the season.
Can you hike the Enchantments Traverse in one day?
Yes, the 18-20 mile (29-32 km) traverse is commonly done as a single day hike, which does not require an overnight permit. Most parties start before dawn at the Stuart Lake trailhead and finish at Snow Lakes 10-14 hours later, requiring a car shuttle between the two trailheads.
When does Aasgard Pass become safe without an ice axe?
Aasgard Pass typically clears enough snow for safe travel without an ice axe by mid-to-late July, though heavy-snow years can push that into early August. Before then, the steep north-facing slope holds snow that requires self-arrest skills and traction, making early-summer crossings a mountaineering objective.
When do I apply for an Enchantments permit for 2026?
The overnight permit lottery opens on recreation.gov in mid-February 2026 and closes in early March, with results announced in late March. Core Zone and larch-season dates are the hardest to win, with success rates often below 5%, so apply for several date and zone combinations.
How cold does it get in the Enchantments at night?
Summer nights in the Core Zone at 7,000-7,500 ft (2,135-2,285 m) fall to 40-50 F (4-10 C), while late-September larch-season nights commonly drop to 30 F (-1 C) or below. Carry insulation rated for near-freezing temperatures even on warm-forecast trips.
