The Big Dipper of the Castle Creek Wilderness
Deep within the remote and rugged Castle Creek Wilderness in central Arizona lies a spectacular and rarely visited geological formation known as the Big Dipper. This incredible natural rock waterfall into a large pool is a must-see for adventurous hikers and lovers of Arizona's wild backcountry.
Overview
The Big Dipper is a vast, bowl-shaped volcanic formation located deep within the Castle Creek Wilderness, part of the Prescott National Forest. What sets this formation apart is its sheer scale and the dramatic, sweeping curves of the canyon walls that give it its namesake shape. This hidden gem offers solitude, breathtaking views, and a chance to experience untouched wilderness. Although it's not widely publicized, the Big Dipper has been noted in geological surveys for its unique topography and volcanic origins.Photographers and nature lovers will appreciate the beauty of the smooth waterfall and pool, especially during sunrise or sunset when the rock faces catch the light in warm tones. The unique curvature of the walls and surrounding cliffs create a natural stage that feels like a secret world hidden away in the Arizona backcountry.
The Hike
Getting to the Big Dipper is an off-the-beaten-path adventure. There are no officially marked trails leading directly to the waterfall and pool, but hikers can follow the Algonquin Trail #225 to Poland Creek and follow the creek northeast to the Big Dipper. The 2-mile hike (one way) ranges from moderate to difficult, requiring route-finding skills. Having a GPS is extremely helpful.
Trail Highlights:
- Stunning views of the Big Dipper waterfall and pool
- Opportunities to spot wildlife such as elk, deer, and hawks
- Remote wilderness with few (if any) other hikers
- Excellent destination for backpackers or day-hikers seeking solitude
- Untouched volcanic terrain and geology rarely seen by the average traveler

Be sure to wear long pants and bring a topo map or GPS, as the trail is overgrown and navigation can be tricky. The hike involves bushwhacking and route-finding, so it's best for experienced adventurers. The trail is all downhill to the Big Dipper, dropping 1200-1300 feet in elevation. Be prepared for the all-uphill hike on the way out. Look for the sparkling mica along the Algonquin Trail, seen in large quantities. Note that there is no way down the 50-foot drop to the pool of the Big Dipper without ropes or a large, potentially unsafe effort skirting around the area to get to the bottom.
Important: Do not attempt this hike during or shortly after rain. The canyon and surrounding terrain are prone to flash flooding, and water can rise quickly with little warning. Check the weather forecast before heading out, and avoid entering narrow canyon areas if there's any chance of storms. Poland Creek may not be passable for hikers after and during rain.




How to Get There
Note that there are no signs marking the Big Dipper, so using GPS coordinates is essential. From I-17 northbound, take the exit for Bumble Bee. This road is called Bumblebee Road (which becomes Crown King Rd). Follow this unpaved road for 25.5 miles. This road is suitable for passenger cars when graded. Watch for the sign marking the Algonquin Trail. Park in the dirt lot on the east side of the road at the trailhead.Trailhead coordinates:
34.21751, -112.30729
Big Dipper coordinates:
34.21451, -112.29698
As a bonus, the route to the Algonquin Trail passes through the historic towns of Bumble Bee and Cleator. And by following Crown King Road an extra two miles past the trailhead lies the former gold mining town of Crown King. All of these unique towns are worth a visit.
Tips for Visiting
- Use extreme caution on the slick bedrock at the Big Dipper
- Carry extra water and food – this is remote country
- Navigation tools (map, compass, GPS) are essential
- Cell service may be weak or unavailable
- Check weather conditions – roads and trails become difficult after rain, and Poland Creek may have high flow
- Let someone know your plans before heading out
- Always practice Leave No Trace principles
