This is a great opportunity so don't skimp and leave a lens at home just to save a little space or a few ounces. Bring a convenient way to carry your equipment. We will not be doing any extensive hiking but a walk of a mile or so is possible. A variety of clothing. Daytime temperatures may be in the 80s but the nights can cool down to the 40s or 50s.
Some rain is possible so bring a water proof jacket or pullover.
Bring comfortable walking shoes. Bring sunscreen, sunglasses, and a hat. Minimal camping is required. I would suggest at least a sleeping bag and an air mattress or sleeping pad, a small ice chest with cheese, crackers, bread, fruit, and plenty of liquids. If you do not like the idea of sleeping outside I would suggest renting an SUV and sleeping in the back.
