Yellowstone and Grand Teton are more than photo ops and zoos where the animals roam free. They aren't museums, either, where magnificent scenery is merely on display. Both parks, unlike a picture hanging lifelessly on the wall of a museum, are works in progress; they are living, breathing wilderness areas. Plant your feet in a comfortable pair of walking or hiking shoes, find a trail head, and set off into the woods with a sack lunch and a big bottle of water. Better yet, if you can afford the time, plan an excursion around Shoshone Lake or to the south end of Yellowstone Lake by boat to areas few visitors ever see. There are isolated spots in Grand Teton, too -- even on the far shore of popular Jenny Lake -- where, with a little hiking, you'll be rewarded by a pristine, forested glade with nothing to distract you but wild moose and an awe-inspiring mountaintop.
If you're more adventurous, take a white-water trip down Snake River Canyon, or let a guide take you up to Grand Teton's summit. In Yellowstone, sleep under the stars and listen to the wolves howl at Slough Creek Campground; or backpack for a week on the Thorofare Trail.
You'll never plumb the absolute depths of these parks -- no one ever will. You could spend your whole life trying, though, and have a wonderful and illuminating time doing it.
It's no one's idea of a fun vacation to end up inhaling exhaust behind a long line of cars waiting for a break in construction at Yellowstone's east entrance, or wearing a T-shirt in a Montana snowstorm. Few things can do more to ruin a much-anticipated vacation than poor planning. So look over some of the crucial information before you hit the road -- it might make the difference between a trip you'll never forget and one you'd rather not remember.
Nothing will ruin a trip to the parks faster than sore or wet feet. Bring comfortable walking shoes, even if you plan to keep walking to a minimum. Bring shoes that are broken in, and if you plan to do some serious hiking, get sturdy boots that support your ankles and wick away water. Early in the season, trails might be wet or muddy; late in the fall, you can get snowed on. The more popular trails are sometimes also used by horses, which can make stream crossings a mucky mess.
Wear your clothing in layers, and bring a small, empty backpack or fanny pack so that you have somewhere to put the clothes as you take those layers off and on as temperature, altitude, and your level of physical exertion change. Cotton is a no-no in the backcountry; synthetic fabrics are recommended because they dry much faster. Gloves or mittens are useful before the park heats up, or in the evening when it cools down again, even in summer.
The atmosphere is thin at higher altitudes, so protect your skin. Bring a strong sunblock, a hat with a brim, and sunglasses. I also recommend bringing insect repellent, water bottles, and a first-aid kit.
Take into account that elevations at the parks are between 5,000 and 11,000 feet; in campgrounds and on hiking trails, you'll want clothing appropriate to the temperatures -- in summer, 40°F (4°C) in the evening, 75°F (24°C) during the day.
