Did this for the second time last Monday; the trail itself isn’t very strenuous until the last mile to the peak. I’m sure if you only hike once a year the whole trail will feel strenuous, but for more advanced hikers the last mile will be the hardest part. Beautiful views of the entire lake from the top, so definitely worth the work. Other reviewers have said the trail is hard to follow, but that is really not the case. It’s very straightforward and easy to follow!! (There are also not really any rock cairns so if that’s what you rely on to follow a trail then I could see how it would be hard for you)
