Luggage and bags:
The best are backpacks with water containers
Clothing/Shoes/Weather Gear: Do not forget to bring sunglasses, tennis shoes, sandals,hat (or buy a sombrero)jeans and t-shirts if you´re planning to go hiking or visiting places because we have a very warm weather, buy if you´re planning to go dancing bring formal clothing to go to the discoteques. Remember that you will make lots of friends in here so please bring extra t-shirts anb be prepare to give them away
Toiletries and Medical Supplies: you´d better bring mosquito repelent, medicine for your stomach because you will taste food that your system is not accustom to, and bring the personal things you use to freshen up such as toothpaste...
Photo Equipment: You can get almost everything you need for your camera in the local market but if you´re planning to go to the country side do not forget to bring extra rechargable batteries to be taken with you
Camping/Beach/Outdoor Gear: It depends on what you have on mind but mostly I reccomend you to go to a hotel because it is dangerous to camp outdoors but if you go with friends bring flashlight and batteries in order to go hunting all the thing you need in the forest
Miscellaneous: El Salvador is hot and humid any time of the year. Rainy season begins usually at the beginning
of May and runs through October, so plan accordingly. Bring light weight clothing
Luggage and bags:
El Salvador is a tropical country, with warm weather all year round, there is a rainy season from may to october and a dry season from november to april. Your packing needs will depend on what you will be doing.
Clothing/Shoes/Weather Gear: The coast is hot all year, so if you'll be visiting the beaches: shorts, sandals, t-shirts, swimwear, sunscreen, sun tan lotions. San Salvador is warm to hot during the day and sometimes it can get chilly at nights. People don't usually wear shorts at night (even when it's warm). If you're travelling between may and october expect tropical rain in the form of downpours usually in the afternoons so plan accordingly. When going to the mountains the temperature changes a lot, the days are warm and pleasant and the nights can get cold, so a light sweater or jacket may be a good idea.
Toiletries and Medical Supplies: The good thing about El Salvador is that you can find almost anything (provided you are in San Salvador, Santa Ana, San Miguel, La Libertad or other major cities.) You'll be able to find all familiar brand products at the same prices you'd expect to pay in North America, so don't over pack since you can buy your needs once in El Salvador
Photo Equipment: El Salvador is full of woderful photo opportunities, you'll be able to find most major brand films, equipment, etc. Photo developing is very, very cheap.
