Top tip... You can also call ahead and order to pick up!
Elfin Lakes is on my list for MTB outing... Your description is similar to others I've heard... Beautiful views, but boring approach.
Ooh, thanks for the tip! I didn't see many other trails that high up, so you might find the MTB pretty tame too. Lots of bikers out further down the hill though!
I typically use MTB to get around alpine places I don't have the stamina to run... so not so much about the technical but the view!
And yes, the trails lower down are a mixture of super fun and terrifying....
