Highlight: Boreas Pass
Boreas Pass (pronounced "bor-ee-yus") follows the Denver, South Park and Pacific Railroad bed. As it was originally designed for a railroad, the route is gentle, smooth, and never climbs at more than a gradual 3% grade. (My wife has nicknamed it "Boringest Pass.") The road is easily passable by passenger cars in almost any weather. However, much of the road is above treeline and the summit crosses the Continental Divide at 11,500 feet, so be prepared for high alpine conditions, including rapidly changing weather. Numerous hiking trail trailheads dot the route. The road is popular with cyclists and distracted tourists. Stay alert and be cautions and courteous.

Directions to Trailhead

Starting Point: Breckenridge or Como

The northern trailhead is in the town of Breckenridge. At the south end of town, Main Street merges with South Park Avenue at a traffic light. The next light south is Broken Lance Drive/Boreas Pass Road. Turn left (east) onto Boreas Pass Road (CR10). Stay on the main road as it meanders up through a residential area for about 3.6 miles. There is a large parking area just before the Forest Service Gate. The southern trailhead is above the tiny village of Como. From US 285, about 6.6 miles south of Jefferson, take a poorly marked, paved road north into Como. This is Boreas Pass Road (CR33). Stay on this, the only paved road, as it winds through town, changes over to dirt, and heads up Tarryall Creek. About 3.1 miles from Como, at a well marked intersection, turn right (northeast) to continue on Boreas Pass Road. Here we describe the route from north to south.

Trint Ladd

Mapping Crew - Colorado

Trint grew up riding dirt bikes in the creek beds of the Texas Panhandle. While attending college in Colorado in the late 1990's, he saw a magazine article about a Ford Explorer four-wheeling club. He never saw his Explorer as an adventure vehicle before, but quickly joined up and caught the bug. With his engineering background, Trint has always respected the factory design of a good truck (and recognized when manufacturers put cheap parts into something marketed for off road use). "A good driver, with a well built, stock truck can do trails that would break a $50k, built-up rig with an inexperienced driver." He put that 1st gen Explorer though hell and it always held up, earning great respect from the "big dawgs" in the club. (And earning the nickname, "The Idiot Stocker.") The truck was christened "BamBam" because of the frequent sounds ringing out from the factory skid plates. Now that Trint is "grown-up" (quotation marks intentional), he's a bit less inclined to dent up his 2011 Toyota Tacoma, but still feels the same way about superior engineering. The "Stocko Taco" wheeled for over 10 years with no mods other than trail armor. In 2021, it finally got a couple of inches of lift... and a new name: "Taco Supreme." Trint's love for the mountains was ingrained at a very early age. 8mm film exists of 18-month-old Trint in a backpack on his dad's back while riding dirt bikes through the mountains of Red River, NM. Although Trint does enjoy a good, tough, technical rock trail, he can often be found on easier, winding, Alpine roads just taking the glory of God's country.
