During one day traveling in Ecuador, all seasons can occur. Reflect all climates and all types of weather in the clothing you take. Ecuador may be on the Equator, but in the Andes the height compensates for the heat. In Quito (2850m) in July it may be a pleasant 20-21°C, but after 7pm, when the sun sets, it becomes chilly very rapidly. The higher you get, the cooler. On the slopes of Chimborazo and Cotopaxi, you will be close to the snow line and, despite the sun, you’ll feel it. A warm jumper, thick pants, a shawl (to cover your mouth against a fierce wind and lashing lava sand), and a rain jacket/windcheater are no luxury. For the jungle and the coast, you will need light summer clothing. But bring something to protect you against the sun. Even with a fully overcast sky, you can get badly sunburnt.
The same applies for shoes. In the jungle and on the beach you do not need walking boots (in the jungle rubber boots are best, but you will be able to borrow some, while on the coast you need only sandals). However, if you want to go climbing in the Andes, you will need sturdy, high, well worn-in walking boots with good tread. In the evenings, in the jungle and on the coast, have a high-collared t-shirt with long sleeves or a thin cotton roll neck sweater to protect against mosquito bites. There is no mosquito netting in the accommodation in the jungle. The windows are fully covered with fine-meshed gauze. A mosquito net is not really necessary but you could consider bringing one. Other important items to pack include: sunglasses, sun lotion and after-sun lotion, lighter, mosquito repellent, toiletries, sun hat, books, first-aid kit, camera or video camera, (spare) camera batteries or film, pocket knife (not in hand luggage during the flight!), rope/washing line, water bottle, alarm clock, pen and paper, passport valid at least another six months, sufficient cash and traveller cheques, a list with the numbers of your cheques and your purchasing slip, if you want a credit card or your bank card, copies of passport and travel insurance (keep separately from the originals), air tickets, a travel insurance pass with the emergency number, diary with important addresses, a good travel guide. Optional: roll of toilet paper, towel and a penlight. Preferably take a canvas bag or a backpack rather than a stiff suitcase, as these are less convenient to transport. Besides, a smaller daypack or a shoulder bag for your daily luggage. To keep your money and documents, it is recommended to take a thin cotton money belt that you can wear underneath your clothing. Make sure you pack some clean clothes in your hand luggage and,other items so that you can go without your other luggage for 48 hours, in case the luggage arrives later than yourself. For example: pack important medication and your toothbrush in your hand luggage. Take care not to pack too much.
