You can find a detailed review of The Boulders in Walker, MN on www.leechlaketourist.com which is a site dedicated to the Leech Lake area so I will keep it short and sweet for you here.
It’s amazing. You will get nothing short of amazing for dinner for drinks for service. I will give you the link to their website (which is the only thing about this place that is NOT amazing) and you will now need to make reservations for the next time you are in town.
No regrets. Just bring some money, because it’s not cheap. But you are paying for the best, you will get no less! See the other link above for local recommendations and check out TripAdvisor, they are #1 in Walker as they should be!
Here are some photos of an Anniversary dinner, we go every year!
