We met a mother bear and cub at the trailhead and there's evidence of bear activity along the trail to Singing Pass. There are several large trees across the trail as you head up to Singing Pass but all are easy to clamber over/under. The bridge at Harmony Creek is gone and the water level is currently high making for an interesting crossing. You can make it across on some rocks but be careful. The bridge over another creek further along is also broken and is slippery with the current high water.
Snow patches start on the trail just before Singing Pass. At the Musical Bumps/Russet Lake junction there is almost continuous snow - it took a while at some points to find the trail in the meadows as there is only the odd spot where the snow clears and the trail can be seen. We hiked in boots, poles were handy on some of the final ascents as the snow was becoming slippery in the hot sun. We boot-skied down the bumps which probably saved us some hiking time. Enough sections of the trail were visible for us to always head in the right direction. Once we got near the Symphony Express chair the trail was no longer visible at any point, but by that stage we could see our final destination (we headed to the Harmony Tea Hut and down the road to the Roundhouse, the road has been ploughed).
Where the snow has cleared the wildflowers are out in force. The views are excellent in all directions, I highly recommend this hike. Some great views of Black Tusk, Cheakamus Lake, Blackcomb and Decker Mountain, Fissile Peak. We rode the Peak to Peak and came down via the chairlifts on Blackcomb Mountain. The hike took us 8 hours to the Roundhouse.
