Packing List for Iceland

Icelanders say there is no such thing as bad weather, only bad clothes. (E. Paul Durrenberger, Icelandic Essays)

I know you can help! I look forward to your comments as to what else we should bring, or what we should leave behind.

We plan to spend a lot of time outdoors: walking around Reykjavik, day hikes throughout the countryside in ALL kinds of weather, swimming, and so on. We won't be camping. We will be getting around by rental car.

Here goes:

sleeping bags (for places with "sleeping bag accommodations"--to save $)
hiking boots
hat/earwarmer
poncho and waterproof pants
good waterproof jacket with hood
swimsuit
binoculars
camping utensils
"flat" ice chest
camping style lightweight towels
kerchief
day packs
vest to wear under jacket for extra warmth
gloves
batteries & memory cards for cameras
travel pillows?
lightweight long underwear
peanut butter & crackers, nuts & dried fruit, trailmix
sunglasses
Voltage converter (220/50Hz, European plug type)
Camera, cables, extra memory cards
Thumb drives (to offload pictures)
Playstation for Web browsing (and camera off-loads?)
Books, sketch pads and art supplies, trip journals
