From Wikipedia: The Flattop Mountain Trail, also known as the Grand Trail or the Big Trail, was built in 1925 in Rocky Mountain National Park in the Larimer County portion of the U.S. state of Colorado. Built in 1925, and rehabilitated in 1940 with Civilian Conservation Corps labor, it is listed on the National Register of Historic Places. The trail begins at 9500 feet of elevation at Bear Lake and climbs Flattop Mountain to a maximum elevation of 12,324 feet on the Continental Divide.

Plan your hike

Practical notes

Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.

Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.

When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
