Quieter than the other Highwood cirques, Arethusa offers various skiing options from steep couloirs to shorter, mellow skiing in the meadows. The south bowl of Mt. Arethusa can be good for lapping when there is sufficient snow coverage.
Park at the main Highwood Pass parking lot and walk 1km south to the Arethusa Ciruqe/Little Arethusa trailhead (parking by the trailhead can be tricky when snow has not been plowed). Follow the summer trail up the drainage. Head left towards Mt. Arethusa. Some mellow, short skiing options can be found in the meadows between Little Arethusa and Mt. Arethusa. Continue up the Arethusa bowl by making switchbacks. The bowl can be lapped or the S couloir above the bowl too is an option but watch out for freshly wind loaded snow.
