The falls are beautiful in winter but the campground isn’t open then (in winter you’ll need a 4WD vehicle to get to the trailhead, or just walk further). The road is rough and I’m not sure RVs or campers could make it, but sedans are fine most of the year. The trails aren’t very long but they’re fantastic both for the views of the National Park, valley, and the waterfall. Camping here is very basic, meaning minimal facilities (vault toilets, byo water/treatment), no reservations, no caretaker, about 20 parking/camping sites, low cost.
