| Welcome to TetonHikingTrails.com |
Welcome to TetonHikingTrails.com, the most comprehensive site on the internet for information on hiking trails in Grand Teton National Park.
TetonHikingTrails.com provides detailed information on more than 45 hikes throughout Grand Teton National Park. The site provides trail descriptions, pictures, key trail features, hike length, difficulty ratings, trail maps and elevation profiles. The authors of TetonHikingTrails.com have personally hiked every trail covered on this website, and have published original content based on those hikes. You may also want to note that TetonHikingTrails.com is now available in an eBook format, which provides convenient access to the information contained on our website while in the park, or on the trail, where internet access will most likely be unavailable. Please visit Amazon for more information.
The authors also have extensive experience hiking throughout the Rocky Mountains and the Appalachian Mountains. You can visit our sister hiking trail websites for Glacier National Park, Rocky Mountain Hiking Trails and Discover the West. Our sites have been mentioned or referenced in a wide variety of publications and websites, including National Geographic Travel, Outside Online, Washington Post, CBS News, USA Today, Men's Journal, Travel Channel, Condé Nast Traveler, Weather Channel, Money Magazine, MSN, Huffington Post, Yahoo News, Business Insider, as well as numerous local news outlets.
In 2023 the author of this website published an expanded edition on the rich history of hiking. Ramble On: How Hiking Became One of the Most Popular Outdoor Activities in the World is now available on Amazon.

| Explanation of Hike Difficulty Rating |
Several years ago I noticed the various rating systems that were being used to gauge hike difficulty levels tended to be too general, or were highly subjective. While researching hikes for a trip to Colorado I discovered a website that attempted to remove the subjectivity out of trail difficulty ratings by means of a mathematical formula. The formula was originally developed by Paul Petzoldt, an accomplished mountaineer and founder of the National Outdoor Leadership School (NOLS). In 1976, he proposed a theory in his book, Teton Trails, to help backpackers calculate their nutritional requirements during a trip. His theory states that one energy mile is equal to the energy required to walk one mile on flat terrain. His theory also asserts that you need to add two energy miles for every thousand feet of elevation gain. In other words, if you climbed one thousand feet over the course of a mile you would use the equivalent of three energy miles.
Petzoldt's theory stood untested for almost thirty-five years. However, in 2010, Western Carolina University’s Exercise Physiology Laboratory conducted a study to measure the energy cost and perceived exertion while walking on flat terrain, with and without a backpack, and compared it to walking one mile with a thousand feet of elevation gain. Results from the study showed that the average additional energy cost for ascending a thousand feet of elevation was 1.6. However, wide differences were recorded among females and males, which ranged between 1.32 and 2.02. The lead researcher for the project, Dr. Maurice Phipps, stated in a WCU news article that the broad range in results was due to weight differences among participants. The abstract from the study also speculates that heavier expedition packs at higher elevations could impact energy costs as well, but further research was needed. Professor Phipps noted that, "It is remarkable that Petzoldt's energy mile theory is so close to the actual energy cost measured during our study." While energy requirements will differ among individuals based on a range of variables, including weight, Phipps ultimately recommends that hikers and backpackers continue using Petzoldt’s method of adding two energy miles for every thousand feet of elevation gain.
As a result of all this, Petzoldt's formula has allowed me to gauge the relative difficulty of the hikes covered on this online trail guide. Of course these ratings are only one indicator of hike difficulty. Each hike has its own variables beyond elevation gain and distance. This includes weather, experience, fitness level, trail conditions and altitude, among a range of other factors. This rating system simply gives the hiker a general reference point between one trail and another.
As a general rule of thumb a difficulty rating of less than 5 is considered to be an easy hike. Between 5 and 10 is moderate, and anything above 10 is considered to be strenuous. Novice hikers should probably allocate at least 20-30 minutes to walk a mile on flat terrain. If you plan to take a lot of photos, rest breaks or choose a hike with significant elevation gain, then you will need to add those factors into your time estimates.
