New/updated info after today's outfitter/cooperator meeting with the Forest Service:
New hours for Kawishiwi (Ely) permit center; May 1 - Sept 6, 8:00 am to 4:30 pm
U.S. Custom (across street from permit center - May 26 - Sept 8, open from 8:30 to 4:30 pm
On May 1st, you can paddle from Lake One into & beyond Insula. Until then, only up to Insula portage from Hudson.
The new Lake One 30F permit means no camping in Lakes 1, 2, 3, 4 or in Hudson, however with that permit you can camp in Fire and Bridge Lake (which is north of the Lakes chain). You can also camp in Insula and beyond, but the Fire/Bridge was new to us until now.
An additional campsite is being developed on Slim Lake.
