Well it looks like I'm going to try for lower elevation for sure. I primarily want to test out my new hot tent and get some fishing in before it gets too warm and before I start spending most of my weekends scouting for bear and deer season...
It looks like Mildred lakes over in the Olympics could be an option based on AllTrails reviews. Will be contending with snow at the top but I think the lake will be mostly opened up by late May...
Otherwise, looking at going up to Cooper Lake...despite the recent cougar encounter over there. Anyone tried getting up there or around Salmon La Sac in late May? The campground doesn't fully open until after Memorial Day weekend due to snow but I imagine that doesn't mean it's totally inaccessible to people with 4x4. Will probably need to call the ranger district up there prior to going either way.
