El Litro RV Park

This is the only RV park in town, can walk to downtown like Hotel California or Iglesia Mision within a mile. They charge us 300 pesos, no Wi-Fi, it has shower, but the shower water not warm than your body temperature, T-Mobile has one or two bar of LTE, sometimes to 3G. Rosters crowing day and night, radio music nearby till late night.

A very basic campground. No other options within walking distance of town, so welcome home!
Nothing special to say about it with either pros or cons. How showers, good (enough) bathrooms, electric and water in each site... it does the trick, for sure. The dogs can get a bit noisy in the evenings as they all start barking with/at each other. A church right next door can have some evening activities to cause some noise as well. All in all; mediocre, but the best you can get if you want to easily visit Todos Santos

We day tripped to TS and checked this place out so we knew what to expect. The owners Sylvia and Pepe are very friendly. Half (?) of the sites are permanent. The spaces are tight, but everyone helped by moving vehicles. We used a full hookup site. Didn't use the toilets (2) or full bathrooms (2). They seemed to be clean enough except one toilet was unusable.
Church next door had some singing going on until 8pm. Occasional dog chorus during the night. Not bad for being in the middle of town.
Campgrounds are rare in this area and if you want to see Todos, this is it.
Telcel LTE. No WiFi.
