My friend and I will be visiting Lassen Volcanic National Park to do some hiking on September 15th, staying for 3 nights before moving on towards Yosemite. We'll have around two and a half days to explore the park, and hopefully also include a quick detour to Burney Falls. We'll be entering the park from the Eastern side, having stayed in Fallon the night before. To get the most out of our visit would it be best to choose a central campsite like Summit Lake and stay there for the 3 nights, or would be better off splitting our time between 2 or 3 different sites? Ideally we'd like to do the Cinder Cone hike, see the Bumpass Hell area and if possible rent a kayak for a while at Manzanita Lake. Suggestions greatly appreciated!
