I love the whole symphony but from the second movement two favorite moments, two details, spring to mind. First, the recapitulation when the solo violin takes flight, like a buzzing bee around a flower, and then accidentally finds itself in a wonderful modulation to E major. The second is the ending. The flowers, that move and dance elegantly against the wind, suddenly expose their Tristan-like soul. From the vast first movement I would choose the huge, yawning creature’s (Pan’s?) first appearance.
