How much of a different perspective and experience of the lake do you get from the boat than you get from the loop road and viewpoints above? Also, I see that a couple of the boats stop on Wizard Island to let you explore for 3 (or even 6) hours. Is this a worthwhile use of our time at Crater Lake, or should we just take the regular boat ride? I am aware that the hike down to and up from the boat ride is quite steep.
Also, what is a realistic estimate for how long it will take us to drive the loop road and stop at the various pullouts and overlooks for pictures? We'll be there the 3rd week in August. Thanks!
