Once a busy mining camp, the now-abandoned Dyersville languishes near Indiana Creek and is accessed by a network of dirt roads including the Boreas Pass railroad grade and a rugged jeep road.

Know Before You Go: When the gate at the beginning of Boreas Pass Road is closed, the road is still snowy and wet and should be avoided until the gate opens. Expect vehicle traffic, which can be heavy on weekends, on Boreas Pass Road.

Parking: From I-70, drive south to Breckenridge on Hwy 9. Turn right at the stoplight on the north end of town onto North Park. Drive by City Market and park in one of the large lots on the left side of Park Avenue.

Description: Pedal back out to Main Street. Turn right and follow it a short distance. Turn left on Boreas Pass Road and climb gradually up it to where pavement ends at about 3.9 miles. Continue on the well-maintained dirt road, which passes through beautiful aspen groves, making this a superb fall ride. Pass Baker’s Tank at roughly 7 miles (see the Baker’s Tank Loop ride). Continue climbing. At about 8.9 miles, look for a fork to the right across the road from some dilapidated cabin foundations. Follow this side road (see the Boreas Pass ride to continue on the main road) as it drops into the Indiana Creek drainage over steep, rocky terrain. After descending for roughly 0.5 miles, turn left onto the spur for Dyersville. Pedal along a forest hillside for a short distance until dropping to Indiana Creek and the few remaining structures from Dyersville. The road climbs steeply beyond Dyersville and dead-ends, so backtrack to the main jeep road and continue descending. Reach an open valley and the spur for Pennsylvania Creek on the left at almost 11.2 miles (see the Blue River/Pennsylvania/Indiana Loop ride). Stay right and descend. For awhile the road and the stream are one. Look for trails on the right to bypass this. Descend onto Spruce Valley Ranch property and past their private firing range. (From this point until you reach lower Boreas Pass Road, you’re on private property; stay on the described route.) The road eventually becomes paved. Pass a stable and descend on the main road for another 0.7 miles. Look for a trail forking right near a wood fence and driveway. Descend on this singletrack, passing several side trails. Veer left below a sometimes dried-out pond. Traverse a hillside and eventually drop into a meadow. Parallel two fence lines and then connect with a gravel road. Turn left and ride out to Boreas Pass Road. Follow it down to Breckenridge.
