I am looking into going camping this time of year.I am not sure what kind of camping l should be looking into though.l would like to do tent camping but I am not sure if October would be a wise time do it.Also, are there any specific camp grounds l should look into this time of year around this area? Right now I am only looking at lodgepole and l have no idea, any suggestions?

Not sure about campground or weather but you picked a beautiful place to go, l am jealous.

It all depends on the weather. Here is the forecast for Mineral Kind, CA, a city at nearly 9000' elevation near Sequoia NP: http://wrh.noaa.gov/forecast/MapClick.php?site=hnx&smap=1&textField1=36.45083&textField2=-118.59389

Only Lodgepole, Azalea, & Potwisha r open year around, when the road is plowed, while others close October 31st or sooner.
And here is some suggestions of itineraries depending how long of a stay you're planning:
