Haven’t been on this hike for a long time, but it is always one of my favs. You need to remember it will be hot at the base of the tram but it gets very cool at the top sometimes. So dress in layers.
I’ve hiked up San Jacinto several times from the tram. Taking the tram is itself a lot of fun, and the contrast from the Palm Spring desert to the alpine mountain climate is fantastic.
I hope they get some more snow — I’d love to go snowshoeing up there.
