We stayed at the Sequoia RV Ranch for two nights and the first point that comes to my mind when I remember about it is how friendly everyone was there. Not only the staff (who are also very helpful), but everyone there. Really, great atmosphere!
The location is also very good, close to the entrance of Sequoia NP, easy to find, but not to close to the main road, so it's very quiet. There is also the river, in which we had a bath... So sweet after a day of hiking!
The only point I would like to see improved are the showers: they were clean (good point) but not free (and not the best we have seen) and there's no way to get quarters outside office hours.
