VivaLaVida went to Toroweap in January 2015, after a nice snow fall. Despite to wet trail, no need of 4WD but high clearance is requested for the last mile before campground and view point.
I agree, to view is one of the best of Grand Canyon I had a chance to see. It's gorgeous!
I also hiked to Lava Rapid, one of the most powerful rapid of all Grand Canyon about 2,000 feet lower on a very steep and difficult hiking trail. Quite impressive.
The trail to Vulcan's Throne was quite rougher than Toroweap but definitely worth it. Have several pictures but don't want to pollute wadewaydo's thread.
