Go here for breakfast at least once. Delicious.
We almost lucked into buying a mobile home directly on the water last year, last second kinda thing that our friends brought to our attention, but was sold underneath us. Would've been super cheap compared to actual homes there and was a nice one. Oh well.
My parents have a trailer up on West in Millers Bay (21st year of ownership for us) with lake access and a slip on the water. Okoboji Yacht Club, best kept secret in 'Boji IMO. Cheaper way to enjoy Okoboji (Trailers go for around 70k but have to rent the land each year). If your looking for a place, I would check this spot out.
