A warm jacket is necessary especially if you plan to visit the Tatio Geysers.
Good walking boots because there is a lot of places you will have to reach on foot.
A hat and sunscreen for the strong sun rays.
A light sweater for the nights . It gets a little chilly.
...And of course a bathing suit for the great hot water baths !!!
In the Photo my great co-travelers, Yuichiro, Sylvie, Akira and Alexandra. We had a great time, and we have been friends since then.
Camping/Beach/Outdoor Gear: Camping is possible so provide yourself with the necessary equipment.
Luggage and bags:
Is necessary something comfortable not like a expensive bag or something because the town is really rustic and everything can get dirty.
Clothing/Shoes/Weather Gear: Different kind of clothes because during the day is hot and sunny so you will need a t-shirt and shorts or light pants, during the afternoon is necessary a sweater and during night you will need a lot of clothes because is cold.
Take a swimsuit because you can go to the thermal baths or even take a bath in the river.
Comfortable shoes, to be able to walk a lot and to climb.
Toiletries and Medical Supplies: Take some wet little towels to refresh, aspirins and of course something for the stomachache.
The sun will be shining all the time so take a good sunblock.
Camping/Beach/Outdoor Gear: There is also the possibility to camp in the town so take all necessary.
Miscellaneous: Don't forget that there is not electricity after midnight so is useful a lantern.
Clothing/Shoes/Weather Gear: The geysers are FREEZING at dawn (sub-zero) so be sure to pack all your winter gear (gloves and hat included) if you want to remain outdoors comfortably until the sun rises. I didn't bring a jacket and even though Cosmo Andino Expediciones (my kind tour agency) was loaned me one, I was still freezing away. Remember that because of the thin air at the high altitude (4000+ m) of the geysers, you don't really have the option of running around to generate heat! On the other hand / extreme, do bring a bikini too because there is a hot spring awaiting you at the end of the geyser trip...
Luggage and bags:
An internal frame pack, 30-litre daypack, a duffel bag to carry water and supplies if going to camp somewhere VERY off the beaten path (such as El Tatio, Andean villages and creeks, the volcanoes, etc)
Clothing/Shoes/Weather Gear: Daytime Summer clothing: shorts, t-shirts, sandals, trekking shoes (your feet will be grateful), swimming trunks, swimsuit, hat.
Nighttime Long-sleeved shirt, fleece shirt and pants, long pants, warm socks, fleece headcap (for winter nights)
Mountain/Higher areas To the above mentioned, add: gloves, fleece/polypropylene balaclava, warm hiking boots, Gore-tex (or similar) parka, windproof pants.
Toiletries and Medical Supplies: Tampons and sanitary pads are in a limited choice in San Pedro: bring your own. Condoms and contraceptives are unavailable at all.
Bring also: Aspirin (best) or paracetamol, high-factor (30+) sunblock, band-aids (for foot bruises), shampoo+hair conditioner (very necessary), waterless soap, antiacids, diarrhoea-healing pills/drops (Viadil, or any other antispasmodic, as stomach diseases here are not of a bacterial origin).
Photo Equipment: 2- 35-mm. (ideal), for B&W and color.
Ultralong telephotos for wildlife, wide angle lenses for those eonormous spaces, small alleys, portraits, and extraterrestrial spots all around.
POLARIZING, UV or Skylight, R25 (25A, red), K2 or K3 (yellow/deep yellow) for black and white.
Kodak film (slides or print) has the best response to warm colors. Fujichrome Velvia (ISO 50) has a very good response in the warm range, and an unmatched, amazing resolution for sky and green colors. Fujichrome Sensia (ISO 100) is good for big wildlife (llamas, vicuñas, birds).
B&W films good for this are Kodak T-Max 100, Ilford FP4 and the old and reliable Agfapan 100.
Lens hoods, caps (front/rear), dust-off or blower, camel hair brush, cable release, lightweight tripod, spare batteries (mostly if you go somewhere cold up there; take a spare to El Tatio, even if you put new ones the night before, and keep it warm close to your body).
Camping/Beach/Outdoor Gear: In summer in San Pedro, an ordinary, beach or 3-season tent is enough for all. In winter, a 3-season is a better choice, as nights in town are bitterly cold, and can reach –15º on many nights.
If going to camp in the wild in the mountain zone (El Tatio, high Andes volcanoes or lagoons, the Salar, etc.),a full-fledged 4-season or expedition tent is necessary, as strong winds, very low temperatures and an aggressive –yet beautiful- environment put high demands on this gear.
Also, bring a camping stove (preferably MSR or any gasoline-burning one, as gas canisters are a bit hard to find), cooking gear and tableware, water container, headlamp, sleeping pad, water purifying filter, candles, wiping cloth (for floor tent), walking (ski) poles, compass, GPS receiver, maps of the general area.
Miscellaneous: A multipurpose electrical socket-lamp thread is useful to plug in chargers in the room or camping, directly to the lamp sockets (there’s usually a US$ 0,50-1 charge for using NiCd/cell phone chargers in hotels and campings).
