The state park seems not to be very well signposted, and lies away from major travel routes. The main approach is along Hwy 119
, a bendy road starting in the south at an intersection with US 6, 3 miles from I-70, then leading north to Nederland and on to Boulder. Hwy 46
) forks eastwards and crosses the southern section of the state park before descending a canyon towards Golden, while the unpaved but good quality Gap Road
branches off Hwy 119 three miles north, following close to the north edge of the park. These two side roads are connected by the short Mountain Base Road
, which is paved but narrow, and not recommended for RVs or other large vehicles. Another route (Ralston Creek Road) branches off Hwy 46 and traverses the less visited eastern section of the park. The visitor center is along Hwy 46, the two campgrounds (both of which have electric hookups) are accessed via Gap Road, while trailheads and picnic spots are spread out along all roads. The highest point in the park is in the northwest, from where the land slopes down steadily towards the southeast, and most sections can be explored by trail.
Gap Road leads through a small residential area to a self-service entrance station (fees $7 per vehicle in 2015) and a four-way junction - right is Mountain Base Road, descending 800 feet over 3.3 miles to Hwy 46, en route passing two trailheads, while left is a spur to Reverends Ridge Campground
, situated on a wooded promontory with only limited views of the wider surroundings. The main road continues a short distance to Panorama Point
, an overlook at 9,300 feet from where distant, hazy mountains are visible to the north and west, through gaps in the trees - tallest is Longs Peak. One of the 11 trails starts at the viewpoint - the 2.2 mile (loop) Raccoon Trail
, rated moderate. This descends 500 feet through the pine forest and follows a drainage into a more open valley, then returns via a mix of long grass meadows, airy aspen groves and small creeks, with some fleeting views of 10,540 foot Thorodin Mountain just north of the park, one of the few places where the granite bedrock is exposed. Back on the road, another trailhead is for the 7.4 mile Mule Deer Trail
, which winds along the foot of two peaks then returns to the start via a path close to Mountain Base Road, loosing then gaining 880 feet. The road next passes the turning for Harmsen Ranch, a guest house, then for Aspen Meadow
, site of the second of the two campgrounds - this is also wooded, but with open, dry meadowland close by. Two paths starting here are the Snowshoe Hare Trail
(3 mile loop, fairly level), partly along two valleys and partly across wooded slopes, and the 1.2 mile Buffalo Trail
, a connecting route that follows another drainage to Forgotten Valley, a location also reached from the south.
