Mainly posting this to make sure that there is a clear report that says the summit of Mount Daniel is NOT an "easy walk-up."
Due to low water levels, the Forest Service road portion of the trip was easy, but 12 miles on a road like that is awful. It took ~1 hour to go the 12 miles. Not too bad on the way there, but it's a LONG hour on the way back.
Through Cathedral Rock, the trail is meticulously maintained and obvious. Strenuous, but not dangerous or challenging beyond the consistent uphill path. There's some (easy) trail-finding between Cathedral Rock and Peggy's Pond (hint: have Gaia on your phone). The trip from Peggy's Pond to the trail that leads to the Mount Daniel Summit is NOT obvious. Most reviews here and on Summitpost say "just follow the cairns!" but there are a ton of cairns. Generally, you want to make your way "up." You'll come across some extraordinarily loose rock on your way to the actual trail, at which point the path will be obvious.
Based on my experience, between 7000' and 7200' it goes beyond "walk up" level of difficulty/hazard. There are some very exposed sections with the path sloping toward a big drop with little to use as hand holds. Around that point, I spent some time talking with a kind fellow who had made the top, and he talked about "moves" (as in, scrambling moves... as opposed to "keep hiking until you get to the top") at two distinct spots after the sketchy section I was on. Upon reaching the next "sloping toward a nasty fall" spot, I turned around.
I'll point out the above is a product of my skill level/level of comfort. I'm sure someone else could hike up to the top without any second thoughts and talk about how easy it was. I just want to make sure that people that have done Bandera, Granite Mountain (the one with the fire lookout on I-90), etc. and are looking for something "more," know that this is NOT a walk-up the way those are. (if you're looking for 7000'+ walk-up, look at the Fourth of July Trail to one of the Icicle Ridge summits. Rock Mountain [the one off of Rt 2 ~10 miles after Stevens Pass] is 6800' and awesome, too.)
Don't let any of this make you think it's not a picturesque trip. You're WAYYY up there, and Peggy's Pond is a great destination in and of itself, and the mountain sights are pretty neat the whole way. Just because getting to the top is a bit tough doesn't mean you should skip the hike as a whole.
After Peggy's Pond, there's no trail in any layer on Gaia, so if you need the GPX, please reply, and I'll see what I can do to post a link. When you're actually up there, even the GPX file doesn't make the path obvious. Note that it's easy to lose the trail after Peggy's Pond on the way back down, so keep your eyes open.
** I didn't go up the Cathedral Rock "trail," but included it in the trip report title being that it's a significant waypoint on the way to Peggy's Pond and Mount Daniel.
