The Yosemite Wilderness has over 750 miles of trail to explore. In planning a wilderness trip, it is important to find the right trip for your interests, time frame, and abilities. A good planning process will enhance your understanding of the park and your safety. Therefore, as part of the wilderness experience, park rangers can provide general guidance but will not plan a wilderness trip for you; you must plan your own trip.
When you have thought about or decided what you want from your trip, you can start planning and researching your hike. A detailed topographic map is a must for any hike. In addition, a good guidebook can help you choose a trip that is right for you. For books and maps, please visit the non-profit Yosemite Conservancy's bookstore. Remember that visiting the Wilderness is an adventure: do not be afraid to explore a new area and discover what wonders it has to offer!
