If you REALLY miss the tourist crowd, the people tugging at you to get you to eat at THEIR restaurants, and overpriced souvenirs, the solution is simple: Go to Atacames. Catch a bus at the north end of the beach that is called "Atacameñita." It only takes about 25min and the cost is $0.25. Of course, you can also go by boat there...faster but more expensive (DO NOT walk along the beach, it's tempting but dangerous!)
The beach is not very big, and to walk its whole lenght will not take more than 20min, but the difference between the two sides is pretty big. Essentially, the locals hang out on the south side...go down there and you will find a nice little lagoon, the adults cleaning the fishing nets, and the kids playing in the water. As you walk towards the north, the beach will be more an more touristy, yet very nice. How crowede it will be depends on the time of the week. At noon (during high tide) the middle part of the beach is barely passable....
Súa is super relaxing...so, you don't want to do too much during the day. However, if you do get an itch to do something, there is a nice little rock you can climb on the north side of the beach. If you want it to be super easy, go during low tide. For more of a challange, go during high tide. During high tide of course, you can get the better pictures of the rock with the ocean in the background...AND you get to feel like a mermaid!
In Sùa there seems to be a bunch of very similar restaurants on the beach street. From the outside, it seems like most of them have similar prices and menús. However, after we had tried a couple, we realized that the one giving you the best deal (the best food for the price) is the one called Malibu. Essentially we ate every meal there for the rest of the week! They soon started to recognize us and we had our own table (in front of the TV showing The Simpsons at 7pm!). The restaurant is owned by a friendly couple, and the chef is really good!
Essentially, the price was average, but the quality of the food seemed to be better than average!
Favorite Dish: Like most restaurants on the beach, the standard lunch has fish and rice as its main course. However, they were happy to change this to meat and frech fries for no extra charge. The food is very well prepared and tastey, and the price for the menú (soup, main course, juice) was only $2. They also have a la carte selection, with prices between $2.50-$12 (they don't cheat you, the meat dishes have plenty of meat!). They also serve breakfast.
During the beginning of the week, the night life in Sùa is vertially non-existent (of course, you can always buy something in a licore store and share it on the beach at night with your friends...). However, when the weekend, and the weekend warriors come, the little straw huts on the beach strip open up. They play fairly load, and often bad music (read: reaggeton), and the coctails are over-priced and actually not very good. If a very happening night life is what your looking for...head to Atacames.
There are several little stores along the strip, but this one seemed to have the best selection, the best prices, and the friendliest owner (they believed in the policy "the customer is always right"...which is rare in Ecuador). The place is owned by a friendly couple, with the husband being from Quito, which makes his Spanish easier to understand. They have some seats and a table outside where you can sit down and enjoy the great little ice-creams they sell for just $0.20!
Do not walk on the beach between Atacames and Sùa, in either direction. It surely is tempting because it is not very far. We though about doing it (walking on the beach btw Atacames and Sùa during low tide), but decided to ask some locals first regarding the safety. All they told us was: "You WILL get robbed." Mind you, I was there with two Ecuadorians and a Colombian girl. Surely, if they would rob us, they will rob a whole group of foreigners!
