Hi Nitro,
May-October can be fantastic walleye fishing. Just depends on what stage they are in. May-June will have you fishing around spawning grounds and first breaks from shorelines. July-October will have fish congregated heavily on mid-lake humps…. July/August tends to have more stability in the weather patterns thus offering a better chance of timing a hot bite. Sept/Oct is my favorite months for trophy walleyes.
Campsites tend to be more full June-August, but usually will be able to find a place to camp, and I’m not too familiar with stuff being stolen. Have to believe thieves would target other areas than campsites… Unless your talking about Bears!! LOL!!
VNP (Voyageurs National Park) has maps illustrating designated campsites, and can fill you in with camping permits…
Rainy is a fishermans paradise!! You’ll fall in love with it!! We feel very fortunate to be able to enjoy this magnificent body of water all year!!
