Opal Cone, Elfin Lakes Hike

Opal Cone, Elfin Lakes Hike

Sharing is caring!

Opal Cone is one of the hikes you can do within the Diamon Head area of Garibaldi Provincial Park. It’s a popular trail to hike if you’re doing the Elfin Lakes Hike, or continuing onto Mamquam Lake.

Opal Cone Hike

We hiked Opal Cone while backpacking Garibaldi Provincial Park to Elfin Lakes and Mamquam Lake. The weather wasn’t great, but we did get a tiny gap of clear sky near the summit and the views from Opal Cone are beautiful!

If you’re staying at Elfin Lakes or hiking through to Mamquam Lake then you should definitely head up here.

Opal Cone Trail Stats

  • Distance: 35km (round trip)
  • Duration: 10+ hours (overnight is better)
  • Difficulty: Easy/Intermediate
  • Elevation: 750 m

To get to Opal Cone, you’ll start from the Diamon Head trailhead just outside of Squamish. The first 11km to Elfin Lakes has some gentle elevation up through the forest on switchbacks before you come out into the alpine at Red Heather Hut.

From Red Heather Hut there’s a slight climb, with impressive views all around, before your final descent down to the lakes.

Elfin Lakes is a popular camping destination and you can set up your tent here if you have a camping reservation, before heading on to Opal Cone.

Elfin Lakes to Opal Cone

To get to Opal Cone from Elfin Lakes, continue past the Elfin Lake shelter and follow the signs.

The trail is flat for quite a while and then you’ll start descending down into the valley towards a river. There’s a bridge here to make the river crossing easy, and from here you’ll follow the trail alongside the river on a very gentle incline and deeper into the valley.

After a few km, the trail takes you right and uphill until you come out on a ridge area and at the base of Opal Cone.

Since we were on our way to Mamquam Lake to set up camp and had our backpacking bags with us, we stashed our bags (taking food items with us) and continued up with just our lighter bags.

There’s a small signpost to Opal Cone, and you’ll want to turn left along a thin ridge-like trail before you descend!

The first part of this trail is quite easy and the views are beautiful. Then the trail heads off to the left with a steep climb towards a large boulder.

At this point, we couldn’t see much but managed to pick out some cairns that guided the way. The GPS maps on our phone helped too!

To the west, you will get a magnificent view of Mount Garibaldi, Atwell Peak, and Little Diamond Head.
