Lemme expand a little Joe. When driving down to San Carlos you'll probably pass through Caborca and Hermosillo, nothing much to see. Like I said once you get to San Carlos its beautiful, San Carlos isn't that big. Guaymas is much bigger, but I was not impressed with Guaymas, filthy, nothing much to see.
I strongly recommend Baja. If you're limited on time take the route south of San Felipe and you'll reconnect with Hwy 1 at Chapala, it'll save you a lot of time, but you'll hit 20 miles of rough unpaved road construction. If you have more time go to TJ, its super easy to drive through TJ if you're heading south on Hwy 1, as soon as you cross the border you'll immediately turn right onto toll Hwy 1 that shoots you out of TJ super quick and you'll head south to Ensenada. The ride to Ensenada along the coast is gorgeous. From Ensenada just stay on Hwy 1 all the way down Baja, Catalina is really neat, I'd recommend not going to BoLA (Bay of Los Angeles), I strongly recommend continuing south to Guerrero Negro, then keep going to San Ignacio (you have to see the old Mission there and the gorgeous town center, so beautiful), then keep going to Santa Rosalia then that's when the best scenery starts. Then Hwy 1 runs along the Sea of Cortez to Mulege, past Bay of Concepcion (incredible beaches, scenery) then head to Loreto, in my opinion the best part of Baja. If you have time you can continue to La Paz or Cabo. You need a tourist VISA (FMM) to go to San Carlos or down Baja, but you DON'T need a TVIP (vehicle permit) for either San Carlos or Baja. You only need a vehicle permit if you're traveling south of Guaymas.
Sorry, I know these last two posts have pretty much nothing to do with Rocky Point, but just answering Joe's question. Delete if necessary, I totally understand.
