With nearly 700 miles of well-defined trails radiating from Yosemite Valley to all sections of the park, and with, for the most part, camps, lodges, or hotels situated within an easy day’s walking distance from each other, conditions in Yosemite are particularly adapted to hiking trips. The hiker may go “light”, depending upon the hotels and lodges for accommodations, or he may pack his entire outfit either on his back or upon a pack animal and thereby be entirely independent. During July and August ranger-naturalists conduct regular 7-day hikes through the High Sierra, stopping each night at one of the High Sierra camps above mentioned. There is no charge for this guide service, but hikers desiring to go with these guides should register at the museum in advance.
