West Rim Trail

Best Time to Hike West Rim Trail

Fall (September through October) is the most practical window for the full West Rim route — temperatures are cooler at all elevations, the high plateau is comfortable in the afternoon, and crowds thin considerably from summer peak. Spring (March through May) brings snowmelt that can leave the upper rim sections icy well into April and makes some lower trail surfaces wet and slick. Summer presents the sharpest challenge: the canyon floor heats intensely through June, July, and August, and the exposed rim provides no shade at midday. Afternoon thunderstorms are possible from July through September; the open, high terrain on the upper West Rim offers little shelter during fast-moving storms. Winter travel is feasible on the lower trail for experienced hikers, but upper sections and Lava Point access are often severely limited by snow and ice.

Trail Tips for West Rim Trail

• The temperature gap between the canyon bottom and the high rim can be significant, especially on overnight trips — pack layers, as conditions on the exposed plateau shift quickly after sunset even in summer.
• During monsoon season (July through September), afternoon storms build fast over the high plateau; plan to be off exposed ridgeline sections well before early afternoon if clouds are developing.
• Cell service is limited throughout much of the park, including along the upper West Rim — download offline maps and confirm your planned route before leaving the trailhead.
• Footwear choice matters on this route: the lower switchbacks are steep and rocky, while the upper rim terrain is uneven and exposed. Sturdy boots with ankle support are advisable for the full route.
• Water is scarce above Scout Lookout — carry significantly more than you think you will need before leaving the lower canyon, as there are few reliable sources on the upper rim sections.

Getting There

The trailhead begins at the Grotto area in Zion Canyon, accessible via the Zion Canyon Shuttle during the operating season, which typically runs March through November. During shuttle season, private vehicles are not permitted on Zion Canyon Scenic Drive, making the shuttle the standard way to reach the Grotto. Outside of shuttle season, limited parking is available near the Grotto. For the full one-way route, hikers need to arrange a vehicle shuttle or pickup in advance — the Lava Point access point is on the far end of the trail system and reached by a separate road. Check nps.gov/zion for current shuttle schedules and seasonal road status before your visit.

What to Expect on West Rim Trail

The West Rim Trail covers a dramatic vertical and ecological shift from canyon floor to high plateau. The lower section climbs through steep switchbacks cut into the canyon walls, with sandstone cliffs rising sharply on either side. As the trail gains elevation, the walls open up and the terrain shifts — enclosed canyon gives way to exposed ridgelines with views extending across the breadth of Zion Canyon. The full route stretches roughly 14 miles one way with more than 3,000 feet of elevation gain, and that profile shapes the entire experience: the climbing is sustained rather than gradual. Day hikers targeting Scout Lookout encounter the hardest ascent in the lower section, while those continuing toward the rim move through progressively more open terrain where the canyon recedes far below and the high plateau spreads ahead. The character of the trail changes substantially with each few hundred feet gained.
