We always use Williams and Hall Outfitters outside Ely on Moose Lake. Call Dave, he can answer any questions and provide fishing advice as well.
We stay at their lodge before entering BW the next morning. They motor our canoe to the first portage to save us a half day of paddling. Then meet us at drop off on our return day. Would be advised if only staying 4 days.
We missed last year due to COVID, but had been the previous 5 years. We usually stay 10-14 days. It is quite the trip, and you will want to return each year. Smallmouth are all we fish for and go middle of June, as that is around spawn. Sorry, know nothing about walleye, but that is the primary target for many fishermen.
Have a great time. Feel free to contact me with any questions.
