During the summer (Dec-Feb) temperatures can range from the 30sF to 70sF directly in the sun. El Calafate is very casual & outdoorsy so pack comfortable hiking clothes. One day we wore tank tops/short sleeves and pants at the base of Mt. Fitzroy, and then bundled up in fleeces, vests, scarves and hats as we hiked up the mountain. Make sure you bring gloves, sunglasses, a hat, a windbreaker and sunscreen for your face. Dinner is very casual and hiking shoes are common at most restaurants. Ladies, it's very windy here so bring something to hold your hair back, wear a hat/hood or put your hair in a braid.
Below is some packing inspiration for women. To read more about El Calafate visit our Argentina page.
