Overview
The Pando Interpretive Loop offers access to one of the most remarkable natural sites in North America: a massive quaking aspen clone that scientists estimate covers 106 acres, contains approximately 47,000 individual tree stems, and may weigh around 6 million kilograms, all sharing a single connected root system. Pando grows along the southwest shore of Fish Lake in Fishlake National Forest, and the USFS has installed informational markers throughout the grove to help visitors understand what makes this organism so extraordinary.
The trail itself is short and flat, making it appropriate for nearly any visitor. The real draw is the science and the setting: walking through thousands of genetically identical aspen trunks, all fed by one ancient root system, with Fish Lake visible through the trees to the east.
The Route
Trailhead to Grove Center (Miles 0-0.5) From the small pullout on UT-25, the path enters the Pando grove immediately. The first interpretive sign explains the basics of clonal aspen reproduction and what defines Pando as a single organism. The trail underfoot is packed dirt with minimal elevation change. The stems here are older and larger than at the grove's edges.
Interior Loop (Miles 0.5-1.1) The interior section of the loop winds deeper into the grove, away from the highway. Signs here address the ecological threats Pando currently faces, particularly overgrazing by mule deer that prevents new stem regeneration. The USFS has installed experimental fencing in portions of the grove to test whether protected regeneration can help the clone recover. The contrast between fenced and unfenced sections is visible along this stretch.
Return Along the Lake Margin (Miles 1.1-1.5) The final portion of the loop curves toward the lake margin before returning to the trailhead. On calm mornings, Fish Lake is visible through the trees to the east. This section has the most wildflowers in early summer, including lupine and penstemon growing at the grove's edge.
When to Hike
May and June offer the freshest new aspen leaf growth and the fewest visitors. The small parking area rarely fills in shoulder season.
July and August are the peak summer months. The grove is fully leafed out and the interpretive signs are fully accessible. Come on weekdays to avoid competition for the limited parking.
October is the most visually striking time to visit. Every stem in the Pando clone turns color at roughly the same time, producing a synchronized golden display that is subtly different from neighboring aspen stands. The phenomenon is most visible in mid-October and is worth planning a trip around.
What to Bring
The loop is short enough that most visitors need only water and comfortable shoes. Many hikers carry a camera because the symmetry of identical aspen stems and the interplay of light through the canopy make for rewarding photography. Binoculars are useful for spotting songbirds that nest in the grove. Individual water needs vary, but the short distance means a single water bottle is typically sufficient.
Trailhead Access
The Pando trailhead is off Utah Highway 25 on the southwest shore of Fish Lake, roughly 30 miles from Richfield. The parking pullout holds 8 to 10 vehicles and fills on summer weekend mornings. No permit or fee is required. Dogs are welcome on leash. There is no restroom at this trailhead; the nearest facilities are at Mackinaw Campground, about 1.5 miles north on UT-25. Cell service is not available from most carriers.
Nearby
The Fish Lake Loop circles the entire lake and passes the edge of the Pando grove, making it a natural companion hike. The Mytoge Mountain Trail offers a longer, elevated perspective of the Fish Lake basin. Before your visit, review current conditions at /learn/checking-conditions-before-you-go.
