I am so happy to have finally made it up Mt. Daniel this year, 3 weeks post head trauma! I wasn't sure it was going to happen. It was definitely more challenging than before I crashed my head, but worth every moment.
Basics first: The road, Fish Lake Road (#4330), is actually in pretty decent condition right now. It's your basic well-used forest road with potholes, washboard areas, rocks, ruts and some spots where I don't know what the heck happened, but it would have seemed like a piece of cake if it wasn't 12 miles to the trailhead. It just takes awhile. I do recommend a high clearance vehicle, however Scatter Creek is completely dry right now so I think any vehicle could make it if you take your time.
Flowers are blooming in the meadow at the beginning of the trail but getting toward their end, but still stunning in the higher elevations of Mt. Daniel. There were several types of berries along the trail before you get to Squaw Lake.
Bugs were not an issue at all until the true summit of Daniel, where the giant flies were obnoxious. I did notice a few mosquitoes here and there on the way down around Peggy's Pond, as it was getting cooler outside. Nothing major at all though.
The only snow to deal with is if you plan to head up Mt. Daniel via a glacier route. Aside from that, the trail to Peggy's Pond and up the Southeast ridge of Daniel is snow free.
The trail up to Cathedral Rock was in great shape. Lots of switchbacks before the meadows, but I don't remember there being any blowdowns blocking the trail (thank you Forest Service!). Once you pass Cathedral Rock and head on to Peggy's Pond, that section of trail becomes pretty sketchy and exposed for a short distance. It has been that way forever, but if you are new to the trail you may not expect it. You will feel like you are walking on a ledge and the trail can be difficult to see, but keep headed around Cathedral Rock and away from Deep Lake and take your time. You will be fine.
Once you reach Peggy's Pond you can take the scramblers route up the southeast ridge of Mt. Daniel by just following the bootpath(s) that continue taking you higher and higher. This is the most frequently traveled route, especially if you have no experience on glaciers and are just out for more of a simple hike/mild scramble.
I kept heading north past the southeast ridge area and headed up the Hyas Glacier route, my favorite!! It is definitely more of a challenge and you do need proper gear and knowledge. Basically, once you get to the back side of the SE ridge, you head west and just start climbing up the enormous boulder fields. You will see the waterfall that is the glacier melt, keep climbing just to the left of the waterfall. There is a slight boot path in places and some cairns here and there.
Once you reach the edge of the glacier, you can pretty much choose your route. Your goal is to gain the ridge up to the left. The glacier was pretty compact so I did not feel the need to put crampons on, although it would have made it faster and a bit easier. I used my ice axe in case of the need to self arrest because it was slippery in places. I ended up going from snow to rocks and then snow to rocks again, etc, instead of going up the glacier the entire way. I enjoy a killer scramble, but the choice is yours really.
After you gain the ridge, pat yourself on the back and shout "hooray!" And then get moving again because you're not done. Turn right and continue up the ridge. You can see the highest point, where the USGS benchmark is, because it's obvious, but getting there takes some time and effort. Just follow the ridge and the bootpath. When you get to the point where you can see Spade and Venus Lakes, there will be some black colored spires that appear maybe impossible to get beyond to reach the true summit. At that point you will need to lose a little elevation and then gain it back again. The boot path is there, just faint. After you pass that section, continue with the path on the ridge but stay high. There is another boot path that goes around lower that is a real pain in the butt. The higher one will require a couple higher class scramble moves, but still much easier.
Soon you will see the true summit and once you get up there, heaven on earth!! You can see Baker, Glacier and all of the North Cascades, Rainier and Adams, Stuart and the Teanaway...basically everything. And the Lynch Glacier is quite the massive site to see to the Northwest! It is just an amazing summit.
I ended up following the Southeast ridge all the way back down to Peggy's Pond instead of taking the glacier route back down, so it was a loop. It ended up being 16-17 miles and around 5,000 vertical feet of elevation gain round trip. A long day, but worth every second.
