I climbed up Incline Trail with my buddy to the summit, in about 7.5 hours including a half hour lunch, 4 hours there, 3.5 back. There's quite a lot of snow near the summit, in some parts coming up to the knees, which made it longer than we would have liked. Walking through snow takes a lot out of you, although it was almost possible to walk on top of it. We didn't see a single person during our hike, which is nice if you like that kind of thing. It's somewhat easy to get lost particularly near one lake near the summit, an area with a creek crossing (look for the u-turn), and also there is a misleading trail marker in one section between two clearings with snow. You will have known you nearly reached the summit when you come to a massive rock wall. It is very slippery on the final stretch to the summit. There is a section which is quite boggy with hard to avoid mud puddles, and parts of the trail are creek-beds which are dry to varying degrees, so expect to get dirty. Just below the summit this time of year, you can find a steady stream of snow runoff, which seems good to drink. Fortunately this time of year seems to have few bugs, although I did see a few in the evening, but it was a warm day. It was fun but pretty tough.
