Search this site for beta on the approach - I know it's been discussed before. I've done both the all-on-snow approach from the ski resort, and also the snow-free approach from the end of the logging road (drop down to creek, climb up to ridge).
While the snow approach is much more pleasant, there is hardly any bushwhacking if you do the other approach correctly (there is a patch of devil's club and dense shrubery near the creek). It's in a dry streambed, and then mostly open forest. Very steep in spots though - like you might want wear crampons in the woods in spots. It took us about 5 hours, but others do it faster (we were carrying ski gear and it was ludicrously hot, like 80F at sunrise).
