The Triple Crown of Hiking informally refers to the three major U.S. long distance hiking trails:
- Pacific Crest Trail – 2,654 miles (4,270 km) long, Washington, Oregon, and California between Mexico and Canada following the highest portion of the Sierra Nevada and Cascade Range.
- Appalachian Trail – 2,184 miles (3,515 km), between Springer Mountain in Georgia and Mount Katahdin in Maine.
- Continental Divide Trail – 3,100 miles (5,000 km), between Mexico and Canada following the Continental Divide along the Rocky Mountains and traversing Montana, Idaho, Wyoming, Colorado, and New Mexico.
The total length of the three trails is about 7,900 miles (12,700 km); vertical gain is more than 1,000,000 feet (300,000 m) (190 miles). A total of 22 states are visited if the three trails are completed The American Long Distance Hiking Association – West (ALDA-WEST) is the only organization that recognizes this hiking feat. At the ALDHA-West Gathering, held each fall, the Triple Crown honorees are recognized and awarded plaques noting their achievement. As of October 2011, 155 hikers have been designated Triple Crowners.

Thru-hiking is hiking a long-distance trail end-to-end. The term is most commonly associated with the Appalachian Trail, but is also used for other lengthy trails and long distance hikes, including the Pacific Crest Trail and the Continental Divide Trail in the United States and Te Araroa Trail in New Zealand. Thru-hiking is also called “end-to-end hiking” or “end-to-ending” on some trails, like Vermont’s Long Trail. Section hiking, on the other hand, refers to hiking a complete trail by hiking all of its individual sections, not in continuity or, necessarily, in sequence.

Welcome to the Pacific Crest Trail community! The trail is more than a ribbon of dirt, it’s a shared experience and place that binds us together. For many, the PCT holds promise of a second home and strong and new friendships. Off the trail, our community remains connected. Whether you are stopped in the street because of a PCT sticker on your car or an emblem on your sweatshirt, join the online discussion, participate in the PCT volunteer community or socialize at events, we welcome you to the fold.

We are a hiking and backpacking group focused on the Pacific Crest Trail. We’re fast becoming a very active Meetup focused on light and safe travel in the wilderness. We have interesting meetings and plans for brief, overnight hikes as well as for more ambitious treks. We’ll learn new skills, hone current ones and develop a network of people you’d trust with your life in the backcountry. We are very open to new trip ideas, lightweight, and ultralightweight backpacking techniques, and the equipment available at home and in the marketplace. We welcome newcomers as well as experienced “outdoorspeople” of all ages, as long as you’re reasonably self-sufficient. We require that any members attending overnight hikes must be currently certified in CPR and at least basic first aid. We will go to the mountains, the deserts, in all kinds of conditions, so bring your common sense and a good attitude! We are looking forward to meeting you!

Rick DeLong’s (aka “Buckwheat”) account of preparing for and carrying out a thru-hike of the Pacific Crest Trail in spring-summer 2009 on a tight budget. Follow-up from 2010 and beyond.

My definition of long distance hiking is hiking trips that are three or more weeks. The amount of preparation, and the mindset seems to change around that point. We covered the John Muir Trail and the Camino de Santiago on other pages of this site. On this page we have the Pacific Crest Trail and some tips we have learned along the way.
