Cycling Millbrook Road
Ride 3.5 miles gaining 1,134’’ at 5.7% average grade (7.4% climb only)
Climb summary by PJAMM ambassador Dan Razum.
The climb starts at the junction of Old Mine Road and National Park Service Road 615 (Walpack Flatbrook Rd). NPS Road 615 goes northeast to Walpack Township.
As of July 2023 NPS Road 615 was closed due to a landslide near the junction with Old Mine Road. The road was blocked to cars but still possible to navigate on a bicycle. So until the landslide is fixed it is not possible to drive to Old Mine Road from Walpack Township (but you can still bike it). We don't know the timeline to clear the landslide but, judging from the vegetation around the landslide, it appeared that the road had been closed for a year or so already. The landslide doesn't affect the climb, the landslide is on a different road, we only mention it in case you plan to approach the climb from Walpack Township.
Cross Flat Brook Creek at the start of the climb.
The climb starts fairly steep as Old Mine Road goes up the hill away from Flat Brook. The pavement is in good condition but there is no shoulder. Since we are in a National Recreation Area we didn't expect much traffic and we actually didn't encounter any traffic at all, perhaps because of the blocked road, as mentioned above. So traffic was not a concern for us at all.
After about a half mile on Old Mine Road we turn left towards Blue Mountain Lake.
The road is a little narrower and it is eventually a dead end, so again, not much traffic. When we reach the Blue Mountain Lakes Recreation Site there is a small parking area with restrooms.
Just afterwards there is a gate with a sign indicating that the gate is closed on weekends and holidays.
We climbed during the week so the gate was open yet it isn't clear why they would close the gate on weekends. There isn't much at the top, where the pavement runs out, so there doesn't seem to be any reason to close the gates... Anyway, be aware that the gate may be closed if you try to ride on a weekend or holiday.
The top is unmarked but it is obvious since the pavement disappears shortly after the top. There is also a parking area at the top to access the hiking trails.
