Wish there was at least One spot at the visitors center big enough for a 30ft RV to park. Since the only way to the main tree is by foot. Since there's a campground they send that shouldn't be a problem. Signage could have been better also, since there's no GPS signal and the visitors center was closed at 9am. We drove past the Giant one and couldn't park in the parking lot so we could get out and walk to it. Big disappointment!
