Believe it or Not! These horses were actually offered for hire. They will take you from the main street of Rosarito, down a few blocks to the beach for a 'run' along the Pacific Ocean!
I didn't want to go, I was content to sit at the cafe and have a few drinks while my friends rode down to the beach. My friends forced me to join them and the poor horse tried, several times, to kill me. (Probably because I weighed too much for the poor little thing.) however, I did survive and so did the horse.
There are taxis and buses that will take you to Rosarito Beach, but to my way of thinking a car is best. Rosarito Beach's main section offers shopping, dining and hotels all near the beach and in a compact setting, so once you're there you can see or do everything by walking. However, two of my favorite places are not in this area and a trip to Rosarito Beach would be incomplete without having a drink at Calafia or lobster in Puerto Nuevo or even going further south to Ensenada. So, I suggest a car.
When in Rosarito, you can easily hire taxis to take you to and from other local cities (like Tijuana and Ensenada) for about $50-75 USD. Establish the price upfront and tip about 10%. The cool thing is that if you are so inclined some cabbies will allow you to drink a beer to make the trip go by a bit quicker. Also, you will avoid any possible entanglements with the police.
As soon as you cross the border you will see signs that will direct you on where to go. You really cant get lost and you will find yourself on the toll road to Rosarito. This is a very well maintained road and you shouldnt have any problems. The signs will also be in English. I cant remember for sure how much the toll road was but i know it was under two dollars.
To cross the border to get back to the US side usually takes alot longer. Sometimes even up to a few hours. Other times the line seems to go on forever but you get to cross very quick. It all depends on how thoroughly they are checking the cars. Sometimes i have been just waived on through and other times they have searched my car completely. It is definately harder to get to the US side. But if you are not doind anything wrong dont worry about it and relax as they let you through. This would also be the best time to get good deals on souveniers as you are waiting in line to cross the border as the vendor know this is the last opportunity to sell you something. Sometimes i will do my souvenier shopping at this time because you can get a better deal. At other times the line goes so fast that i miss out on my shopping.
Expect that on big weekends the line to cross the border might be very long.
Crossing the boarder from the US side to the Mexico side ususally goes pretty smooth. You might get a red light which means go to inspection. This is totally random and you might not have to even get out of your car. they check your car real quick and then your on your way. If you do get asked to pullover as you are crossing the boarder dont panic its all routine.
Most times you get the green light and you just keep on driving with no problem.
From anywhere in the North America or the world, head to San Diego, California. From there you can take either Interstate 5 or 805 south towards the Mexican border. This is of course if you are travelling by car. Upon crossing the border you would follow the signs that will take you to Rosarito/Ensenada Toll Road (Also known as the scenic route). The toll road to Rosarito will cost you about $2.50 (that's now, I'll keep prices updated). The road is truly beautiful but be mindful of your speed, you don't know when a Mexican highway patrolman will pull up next to you! Upon leaving Tijuana and Playas the Tijuana, you will be in Rosarito in about 15-25 minutes, all depending on how fast you drive.
Should you be traveling by bus, head towards Tijuana's Estacion de Autobuses (bus station) and take a local bus to Rosarito. The journey is short and inexpensive by bus, so if the conditions present in the bus are not of the 5 star variety, you won't mind it too much.
Another option is crossing the border by foot and hailing a cab and having him/her drop you off in Rosarito. Try to haggle the price down because some of them will charge you an arm and a leg!
If you are staying in the hotels towards the south end of Rosarito Beach, which is where all the more happening clubs are, you really won't require a vehicle. You can pretty much get around by foot on the main drag. I can almost guarantee you that aside from a walk to the beach, the furthest you may go from your hotel room (save Puerto Nuevo for their delicious Lobsters) will be within a four block radius.
You can find mini-marts, licquor stores, taco stands, restaurants, clubs, and pharmacies on almost every block.
Should you require motorized transportation around Rosarito Beach, a taxi is your best bet. Once again, try to bring the price down, just don't be rude about it. Just try to reason with your driver, if he doesn't seem receptive, just let it go and find yourself another taxi driver. There are many around!
Youi can get to Rosarito from Tijuana easily by cab. It's about 30 minutes and costs yuo 10 peso. get the cab at Madero between Calle 5A and 6A. For the trip back you can just flag a cab on Juarez. By car you will find your way easily along Rte. 1.
