Up the Boott Spur Trail, great option to get amazing views down into Tuckermans and Huntington Ravines if you have the weather. The longest route distance wise but I think the best for views and pleasure.
"After the first glass, you see things as you wish they were. After the second, you see things as they are not. Finally, you see things as they really are, which is the most horrible thing in the world."
