Why Visit Opal Cone
Opal Cone rises as a distinctive volcanic cinder cone within Garibaldi Provincial Park, offering hikers a tangible connection to the region’s fiery geological past. Its dark, loose slopes contrast sharply with surrounding snowfields and turquoise glacial lakes, creating a landscape that feels both remote and otherworldly. The summit delivers panoramic views of the Mamquam Icefield, Atwell Peak, and the broader Coast Mountains, making the effort worthwhile for those seeking quieter trails beyond the park’s more famous destinations.
Getting There
Access begins from the Elfin Lakes trailhead, reached by driving north from Squamish along Highway 99 then turning onto the well-signed Mamquam Forest Service Road. The final 11 kilometres are gravel and suitable for most passenger vehicles in dry conditions; high-clearance vehicles handle it more comfortably after rain. Parking fills quickly on summer weekends, so arrive early. From the trailhead, follow the wide Elfin Lakes trail for roughly 11 kilometres to the lakes themselves, then continue south on the marked Opal Cone route.
The Hike
The full round-trip distance from the trailhead measures approximately 26 kilometres with 900 metres of elevation gain. Most hikers spend the night at Elfin Lakes campground or hut before tackling the final 4-kilometre out-and-back to the cone. The trail crosses alpine meadows, skirts small tarns, and climbs steadily over volcanic rubble to the summit rim. Expect loose footing near the top; trekking poles help on the descent. Allow 8–10 hours total for fit hikers completing the journey in one long day, or split it comfortably over two days.
Best Time to Visit
July through September provides the most reliable snow-free conditions and longest daylight. Early July may still hold patchy snow on north-facing slopes, while October brings early storms. Winter travel requires avalanche awareness and ski or snowshoe experience. Always check current park conditions before departing, as weather in the Coast Mountains changes rapidly.
Nearby Attractions
Combine the trip with a visit to nearby Elfin Lakes for swimming or photography, or extend further to Garibaldi Lake and the iconic Black Tusk. The broader Squamish area offers additional hiking, mountain biking, and river rafting opportunities on either side of the park visit.
