Did the Spray Park Loop starting and ending at the Mowich Lake Campground, clocking 17.4 miles and 4980' elevation gain. The road to Mowich Lake is washboard gravel, but should be easy with any vehicle if you go slow.
On Sunday, August 28 there were sparse wildflower blooms remaining in the Spray Park meadows, mostly concentrated around streams and springs. There was one short (50') section of snow along the trail near the high point above 6500', which was soft and had a well-worn path through it. The rest of the trail was well maintained and easy to follow. Some huckleberries were ripe along the trail, but also not super abundant. All stream crossings had log bridges or better, and most had a handrail, too. I'd recommend the short side trip to see Spray Falls, too.
I opted to cross the Carbon River over the suspension bridge, and had to follow pink flagging to find the downstream river crossing to connect back to the Ipsut Camp direction, finishing this loop to Mowich Lake. That last climb from the forest and then up in the afternoon heat was well-graded at first, and then became rockier toward Ipsut Pass. The final 1.5 miles from the pass back down to the lake were the only place I saw crowds all day. I'd come back and do this a few weeks earlier next time for more flowers!
