From Lima in a 20 hour bus ride. There are plenty of bus company options, such as Cruz del Sur and CIAL and OLTURSA which are the safest (16 hour drive). You can also take a plane in the Lima airport to Piura, which is two and a half hours from Los Organos by bus. Make sure you catch a safe taxi at the airport to EPPO the only bus company with a service to Los Organos (USD 5). Or you can hire a cab to do the job (U$D 50 app)
The mototaxis (motorcycles adapted to carry from 1 to 3 passengers in the back) are the only public transportation available in Los Organos. You can get a ride from the town to the beach for 1 sol. You can also rent a car, a bicycle or a motorcycle.
Go to the beach. In Los Organos the beach is very quiet and lonely. You may see a few people walking by, but there are no crowded beaches, so it is a great place to rest peacefully. There is a main dock, where the fishermen extract fishes like Mero and Congrio. You can see some pelicans and a lot of crabs in the sand. Here you also can swim with big Turtles (5 sol, 2019).
Go to town. It revolves around the main square, where people gather and hang out during the day and part of the night.
Water sports. The waves are great to practice some surf or kitesurf. The best surfing spots are in the beach called Punta Veleros. You can also go fishing and scuba diving.
There are no stalls in Los Organos. You can buy some local products such as clothing and fruits at the local market (mercado). There are convenience and grocery stores, drugstores (boticas), restaurants, an ATM, and almost everything you need to stay for a while. In case you need something else, you can go to Talara, a city which is an hour and a half from Los Organos.
There are plenty of restaurants, most of them serve traditional peruvian food, but there are some which offer international food as well. You can eat a whole menu for 15 soles. Most of the dishes include fresh fish or seafood. The Cevicherías offer ceviche (raw fish or seafood "cooked" in lemon juice). Try to avoid dairy products as they don´t tend to keep the cold chain, even in hotels.
The most common drinks are pisco and beer. You can have a pisco sour (pisco, lemon juice and sugar), a chilcano de pisco (pisco, lemon juice and ginger ale) or a Perú Libre (pisco and coke). But you can also get rum, whisky, vodka and other liquors.
