Best Hiking Window

No recommended window exists for this weekend. Saturday presents dangerous storm conditions with near-whiteout visibility and hurricane-force gusts. A brief lull Saturday night offers slightly reduced winds but remains bitterly cold with continued ice. Sunday deteriorates again with a second low bringing freezing rain, mixed precipitation, and possible thunderstorms. Postpone this hike until the pattern fully clears — likely mid-next-week at the earliest. Monitor updated forecasts before committing.

Trail: Jewell Trail, Gulfside, Jefferson Loop, Clay Loop

Conditions: Dry Trail, Mud - Minor/Avoidable

“Had a great hike going up and down on the Jewell. Used Gulfside to summit Jefferson, then backtracked to Mt. Clay and used the Clay Loop to summit Clay. I had never done clay so I figured while I was just bagging Jefferson on the day I would. It's a nice hike up with some awesome views into the Great Gulf of Washington. Awesome views of Adams as well! Not a lot of mud but it's there. Mostly on the lower sections of the Jewell but very avoidable. Lots of people out today enjoying themselves. Shared the summit of Jefferson with about 15 other people at its max, including Adam Hoyt, White Mountain Youtuber. Real friendly dude, and he makes very cool videos, and for me as a mostly solo hiker, its helpful to have an idea of what I'm hiking into. All in all the trails in the Presidential Range are gonna be in good shape until Sundays rain. Enjoy!”

Trail: Castle Trail, Jefferson Loop, Gulfside, Lowe's Path, Presidential Rail Trail

Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Mud - Minor/Avoidable, Snow - Spring Snow

“up castle trail to Jefferson. bits of mud here and there but mostly dry, no snow nor ice anywhere on this trail. castles are looking cool like usual. still waiting on spring to come to the higher elevations. from Jefferson went across Gulfside to Adams. Gulfside was all dry except for a 50ft or so area of snow that's a bit sketchy to cross. from Adam's went down Lowe's path. Nice to see a handful of improved sections of trail on there. no snow nor ice on Lowes either. A bit more mud towards the bottom of Lowe's but nothing bad. Bugs started getting really bad the last mile or so before the rail trail.”

Trail: Airline, Osgood Trail, Gulfside, Jefferson Loop

Conditions: Dry Trail, Wet Trail, Mud - Minor/Avoidable

“Woke up after not sleeping well multiple nights in a row, but had all my gear packed & food prepared for my planned effort & already took the day off from work. Unfortnately The whole day i ended up feeling off after not fully recovering from a presidential traverse last weekend (achilles/knees/feet), sleeping poorly, etc. This manifest itself in me tripping quite a few times/not being able to hold a regular pace & move efficiently. Anyway.. The forcast was a high of 46 on washington with 20-25 mph winds. There was not a cloud to be seen in the sky all day. I started at 0530 from valley way up airline. The water had frozen overnight & it was about freezing in the parking lot. A great day in my opinion. I brought a single microspike in case it was absolutely needed. Didnt even bother on what remains of the Jefferson snow field. The way to handle this is 'kick in' to the snow and move slow to prevent a slide. Most of the day above treeline it was a bit hard to stay warm, but this was mostly a personal choice (i had the layers to stay warm). Later when i got below treeline i missed the feeling as it was hot and humid (hot for spring). Aside from the mentioned personal issues it was undeniably a choice day to be above treeline and i only encountered a handful of people. The views via Airline are unmatched on a clear day, even feeling off a great day to be up above.”
