We stayed in the lake house cabin. Great location right on the lake. Great view although the cabin has no place really to sit outside to enjoy it. There is a boat dock, which if you rent or have a boat is great. Also if you bring your own chairs that is a great place to sit and enjoy the view.
The cabins were described in some reviews as "rustic". The lake house went WAY beyond rustic...it was filthy! Cob webs everywhere with tons of bugs caught in them. floor was gross and super old. Kitchen was dirty. Place hadn't been dusted this century. Beds were OK. On top of all that our 6 year old found 2 magazines of bullets for a 38 magnum. What the hell!? There was also medication (in arms reach of a child) that expired 15 years ago and spices and random boxed food in the kitchen that also expired over 10 years ago.
Grand lake is beautiful but I would recommend enjoying it from another location
