Health & Safety

Common sense should be your guiding rule when visiting these parks, but here are some of the basics:

Although some of the bridges that cross rivers and streams look inviting, resist the temptation to use them as diving boards -- it's not only dangerous, it's illegal.

Trails, especially ones over rock and granite, can be slick. Be especially careful along any rivers or creeks, such as Mist Trail in Yosemite, where wind and water can make for treacherous conditions.

Always carry more than enough water, especially when going into higher elevations where our bodies require more hydration.

Under no circumstances should food be left in tents, cabins, or cars. There are storage lockers and bear-proof containers throughout the park -- use them.

Under no circumstances should you feed a bear -- or any wild animal, for that matter.

Always carry a map if you go hiking, even for short day hikes.

The Bear Necessities

Bears have broken into thousands of cars in Yosemite National Park. If you'd like your vehicle left intact during your visit, never leave food inside your car; use the storage facilities in the park.
