I myself am doing a 3 day backpack trip this weekend. we are riding out of grantsburg or siren and will ride to brule. Have cabin reserved in brule for both nights. Day 2 we will explore the bayfield/cornucopia penisula. Hoping to find some off trail play and we will definetly be considering the ice caves. day 3 ride back to rigs and head home. There are multiple routes to choose from. I did notice the previous mention of parking in the PD lot in st. croix falls...that seems like a good option as well. There are a lot of good options posted here...anyway you cant go wrong!
