Cardrona & Treble Cone Spring Events Guide

Spring keeps the best days up its sleeve, and it’s often when we see the season’s biggest snowfall. Better yet, the events calendar is stacked, so come participate or spectate. Enter a race, join a jam, or park up on the fence line with a hot choc and cheer your mates on. Plus, we’ve got weekly DJs Friday – Sunday at both maunga to soundtrack your laps.

Here’s what’s happening up the mountain this spring that you’ll want to know about:
