At a bare 1,000' Oxford Mountain is the lowest mountain on the NJ1K list, but presents more hiking challenges than mountains hundreds of feet taller.
Oxford Mountain's forests are among the thickest to be found. Vast sections of woods are overgrown with pricker bushes and dense trees. Other sections of forest are extremely rocky. Woods roads are few and far between, dissolve back into the woods, and do not lead to the true summit area.
The southwestern subsummit, Hill 888 (aka, "The Mount of Thorns") lacks any view, but the true summit has obstructed views to the northeast of County House Mountain.
Parked at the pull off of Axford Ave (or Oxford) and walked up the road to a woods road that headed in the direction of Sykes Gap. The road split but I kept to the left and this took me fairly close to the summit. I bushwhacked the final hundred feet to the summit and found a cairn that marked the high point. For the most part an easy bushwhack although there were some briars towards the top.
Climbed from parking turnout (N40.81484° W74.96831°) and started up to Oxford Mountain first. Made it up in about 1/2 hour. Set a course straight across to the summit of County House Mountain and went down Oxford and up County House. This was doable but was difficult. Rocky areas, some a bit on the steep side. Leaves covering rocks, roots, depressions. Overall distance 2.6 miles, with 902 of elevation gain. Went as far as the no trespassing signs on County House Mountain. Slow going. Overall speed 1.1 mph due to sketchy terrain. In the end, all good.
I should have used Steve Welgoss' directions!
I parked at a pull-off on Axford Avenue, just north of the stream and started bushwacking from there. I crossed several ATV trails, but they always seemed to be heading in the wrong directions. But the multi-flora rose and barberry wasn't bad on the way up. Found a rockpile at the summit and added a few addition stones. On the way down, I found an ATV trail that took me back to Axford Avenue. Overall, it was less than two miles round trip. Not much of a view from the top. Not a difficult walk.
Parked at N 40 48.769 W 074 58.265, and took the woods road up, bearing right at the 2nd split (the first one rejoins in about 200 yards), following it until about .25 mi from the summit, before bushwhacking the rest of the way. Once there, went in a straight line down the steep side before ascending back up toward County House. While there wasn't much overall distance, this one had a high degree of whacking difficulty due to stickers and steepness on the way to the 2nd summit.
