I plan to travel with my parent from 6/5-6/9. fly in from SFO, and fly out from either SEA or SFO. we have not purchased return ticket yet. If there is no snow issue at Lassen Vocanic, Crater Lake and Mt Hood, we plan to fly out of Seattle, otherwise will fly back home from SFO.

We visited Seattle, Olympic, Mt Rainier, Portland, Columbia Gauge, Multnomah Falls, Yosemite, Monterey Bay, partial big sur last June. This time, we plan to visit redwoods NP, Lassen Vocanic NP / Manzanita Lake (North entrance), Crater lake NP, Mt Hood, and cannon beach.

This is a road trip, no hiking, it will be best if only need to walk a very short distance (like 100 feet) from parking lot to take a group picture.

We don't have snow chain. and have some questions for the area with high elevation

1) Lassen Vocanic

I am not sure if I need to skip Lassen Vocanic NP, that will cut 3.5 hours and 137 miles. internet post suggest I will most likely encounter snow issue too.

2) crater lake NP

I’m aware crater lake NP rim drive and north entrance are closed for the season. internet says usually south entrance to the south rim should be open early june.

as long as we can stand by the south rim, and snap a picture, it's sufficient.

3) mt hood

after crater lake, we plan to drive to Trillim Lake, Timberline Lodge / Mt hood.

Typically will we encounter snow issue around Mt. Hood?

If early June is not good time for this trip due to snow condition, I probably will change plan and do SFO ->Yosemite -> Tiago road -> north to Lake Tahoe -> to SFO. I am also open to other idea.

Thank you!
