No surprise, I'm going to have a contrarian view. Could you do the hike? Sure. It's just a matter of how long it takes you. Would you want to do the hike is the question? If the lift is spinning, the answer IMHO is always no. If the lift isn't spinning, I'm in the camp of I'll find plenty of other fun lift served stuff to ski.So I'm 68, have a knee that needs replacing and have never hiked up to top of Castlerock. Been riding the chair since before they took half the chairs off the line whic is before they replaced the lift so I've skied everything up there and I'm sure I can get down. My question is, would I be ok with the hike up the ridge? If it's just a packed trail I'd be fine with that. But if there's scrambling or tricky bits I dunno... Hopefully it will be open when we get up there.
The hike isn't flat. There are portions that you pole, ski, skate, and hike up. I find it tiring and it cuts my day short.
I'll also add that my skis are pretty heavy.
