The next park we stopped at was actually two parks. Same (or similar) sights in each park as well - Big Freaking Sequoia Trees. The tow parks even share the same website. So why are they two different parks you ask?
My understanding is that Sequoia was created before Kings Canyon (it's actually America's 2nd national park) to protect the Sequoia trees, then 50 some odd years later Kings Canyon was created to protect the trees to the North. They all share the same root system and driving between the two it's difficult to tell where one ends and the other begins.
Personally, even though they are very similar, I found myself liking Kings Canyon better. It was a bit less crowded, and I found Grant Grove to be a much better location for getting some Sequoia pictures.
So now a few must visit spots in each park(in no particular order):
So I don't like heights, and if you don't like heights this might not be the best trail for you. But you really should suck it up cause it's an amazing view from the top. Its several hundred steps to the viewpoint at the top and might be a bit tough for some people, and if it's raining or if there is risk of lightening then they close down the trail. Also parking sucks so try to get there early in the day when it's not crowded. I know I'm spewing out a bunch of negative stuff here, but check out that view!
Probably the most popular spot in the park and for good reason - this tree is the largest known living single stem tree on the planet. It's between 2000 and 2500 years old, which I'm told is middle aged for a Sequoia tree. Meaning that the biggest tree in the world still has some growing to do. Hard to believe when you see it that the tree can get any bigger. It's something you can't miss when you visit the park. Downside is that its popular, super popular, have to wait in line for a picture by the tree popular. But at least the park service knows it popular and they all
