This extraordinarily nice city is located 70 miles South of the international Border (90 minutes drive from San Diego CA). Is Baja's third largest City; if you haven't been there, you should go. If you have, surely you'll enjoy a return visit.
Ensenada presents a big vacation package. There are excellent stores and restaurants, plus a lot of freebies like La Bufadora, the sea geyser at the end of Punta Banda, and the unsurpassed bay view from Chapultepec hill, the crowing jewel at the north end of town.

If you are kinda stingy with your pesos, you can take the free road to Ensenada. It can be a pleasurable drive, but the toll road more closely resembles U. S. highways. If you take the coast hugging toll road you are going to pass through three tollbooths. The fees keep changing, but you should be able to make the whole trip for a couple of dollars in tolls.

If you take the free road (and its been used for years by thousands) you'll have a beautiful drive, mostly along the coast although there are areas where it will take you inland somewhat and you even have to climb a mountain pass. Whichever road you take the trip can be divine.
