Accessible via dirt bike road only. 2 miles of non-paved trail-like driving required. Would not recommend unless you have an off-road vehicle/truck
I car camped just off the road,past the campground for 2 nights here. There was several rv in the campground. Verizon signal good.
So when you're camping at Sequoia, one thing to keep in mind is this: there are set campsites so you won't be by yourself. Majestic scenery aside, there's not much privacy to be had. But it is quite a place to be. There's awe inspiring scenery everywhere, including near the site.
