Thanks all for the prompt replies
! Got in contact with the marina at Colter Bay through Grand Teton Lodge Company, the concessionaires for the park. They said a person can park a boat on trailer of my size in the parking lot at the visitors center for a max of 3 days. Certainly takes a load off my mind knowing that. Yeah, oh no We were up there in '17 mid Sept. tent camping and disappointed having no lake view sites available. Was told they start rolling up the campsite loops for the winter starting with the ones closest to the lake (most senic
) and working toward the main road. Visitors center was also closed as was the cafeteria but that wasn't what we were there for anyway.
Sad that you go during off season to avoid being crowded but still can't avoid having to camp right next to someone else. Still looking forward to the trip though and will be boondocking most of it!
