Gate hours may vary depending on weather and maintenance needs. Many trails here become very muddy when wet and are closed at those (few) times. There is no potable water in the park, so be sure to bring plenty of your own.
The park is open all year but can be hot in the summer months - plan your runs then for early morning or evening. There is also a LOT of poison oak (and some ticks) here and staying on the trails is the best way to avoid or minimize contact with these. If you let your dog off-leash, be prepared for a wash and tick check after your run.
This is a very good road for running, even when it's wet.
After you pass through the first (main) gate on the Entry Road (also called Roxy Ann Road), you'll come to a second gate. Right below this is the lower parking area. Park along either side of the road but do not block the gate or the road. Be aware that large quarry trucks and smaller maintenance vehicles use this road system.
If this second gate is open, you can continue on up the Entry Road to the large upper parking lot (with portable toilets) on the right (west) side of the road. Do not drive past this parking lot as the only vehicle traffic allowed past here is that for the quarry. The Loop Road starts (or ends) directly across from this parking lot, at a yellow gate that is closed to unauthorized vehicles.
The Loop Road is a very popular hiking, biking, or running route when other trails in the park are too muddy to use. It is also a great way to avoid any possibility of contact with the poison oak commonly found in the park. And it's popular those few times that Roxy Ann is blanketed by snow.
From the yellow gate, the road climbs gently past a picnic area (with a portable toilet) and then works its way around to the east side of the peak to a junction with Tower Road
- a gravel road to the communications towers on top of Roxy Ann Peak.
The Loop Road continues along the east side of the peak passing junctions with the Lithic Trail
, the Rock & Roll Trail
, and a spur of the Manzanita Trail
. There are usually great views of Mount McLoughlin along here. The Loop Road soon comes to the quarry off the southern border of the park, where a very short trail takes you past the quarry itself and on to the quarry's main road (also called Roxy Ann Road).
Follow this road (be aware of quarry trucks) northwest past junctions with the Greenhorn Trail
, the Manzanita Trail
, the Madrone Trail
and the Oak Trail
to the upper parking lot to finish the loop.
