Part 2 of reply:
In Kings Canyon, Azalea Campground is right near Grant Grove – that is a “must see.” (Great in the moonlight, too!) Muir Grove, near Dorst, is a wonderful hike to a magnificent and quiet grove -- quieter than the General Sherman/Congress Grove/ Giant Forest area.
Also, the road to Cedar Grove should be open by June -- lots of great campgrounds right by the river. If you have bikes, riding along the river is very pleasant, except on weekends.
On the 395 side of the mountains, there is a lot to do and see in the Mammoth area. Personally, I find it kind of busy right in town. We really like the Bishop Creek area -- Four Jeffrey campground should be open by then. The trailheads to Long Lake and Lake Sabrina start at 9500 feet and go up from there -- there might still be snow in the shady patches of the trails.
