|Mount Rainier from the Naches Peak trail.|
Tipsoo Lakes are sporting an excellent show right now - probably peak. Yakima Park at Sunrise and Berkely Park are also rocking the look, with peak probably happening later this week, based on what I saw last Saturday.
The Naches Peak Loop trail is looking very nice right now. I would guess peak is still a few days away - maybe by this weekend.
Grand Park still looks very nice based on reports I've received, but is on its way out as one would expect.
If you are a fan of avalanche lilies, Spray Park or Lake Eunice is for you! The Paradise area is also offering a carpet of white as most of the snow melts. I would guess Paradise and Mazama Ridge are still on target for their prime show around the second weekend of August or so.
I hope this helps in your planning! If you have any additional beta, please feel free to share. Hope to see you on the trail!
Edit 8/1: The park web site is stating flowers at Sunrise have indeed reached peak!
