From I-70, take the Eagle exit and drive south across the river. At the traffic circle just across the river, head west on the old US 6 highway. Follow sings to the Sylvan lake State Park turnoff which comes at the next traffic circle. Drive south and SE on the Sylvan Lake Road through residential areas to an intersection with the Brush Creek Road. The Brush Creek road is variously identified as CR307 or FR400. Turn right (SE) and drive several miles, passing an extensive golf course on your right. A little past the golf course, turn left (east) onto FR415. From this intersection, it is 6 miles to the Yeoman Park Campground on what is called the East Brush Creek Road. Just past the campground, (.3 mile) turn left onto FR418 to Fulford. It is 3.8 miles to the turnoff for Fulford on relatively good, graded dirt road with some potholes. In another .6 mile, there's an intersection with FR419. Continue on FR418. In another mile, you'll intersect FR435 and shortly past that, FR421. Always stay onFR418 which becomes known as the Nolan Creek Road on the Trails Illustrated map #121. By now, the road is degrading and becoming rougher, but higher clearance SUV's can still navigate the conditions. At 8.7 miles from the turn onto the Fulford road just past Yeoman park, you should come to the parking for the Polar Star Hut at a switchback. Turn left at the switchback and if you have higher clearance 4WD, continue the last .7 mile to the New York Mountain TH at 11,210 ft. The drive from Eagle will require a minimum of one hour if not longer.
At the trailhead, there's a little room for a vehicle camp or just up the trail 50 - 100 yards, there are some good tent sites. Yeoman Park CG offers a more civilized alternative but is typically full on weekends. At the trailhead, we have found the mosquitoes to be quite voracious both times we've been there in both early and late July.
