Great place to get in and out of. You need a park sticker on your vehicle though. There are 4 docks and a fuel station as well

The marina is on the Lewis and Clark Lake. They rent powerboats for use on the lake. They have rentals for all day and a two hour minimum. The marina also boasts a shop and a restaurant inside the state park. Be aware to visit the marina you may be required to pay a fee to enter the park. The park is also nice with campgrounds and public bathroom and wash facilities. I would recommend making reservations in advance or renting boats early in the morning. Overall, this is a good way to rent a boat to enjoy a day on the lake. read more

I think the other reviewer (7/15/15) might have been talking about Lewis and Clark Marina on the South Dakota side of Lewis and Clark Lake instead. Weigand Marina does have a small convenience store, but there is no restaurant anywhere in the park itself -- that's Lewis and Clark. Weigand is a nice little marina on the south side of the lake, but if you have a sailboat or larger powerboat, be careful of the very shallow approach areas to the marina basin. It's a little inconvenient to get to by road -- it's four miles over a very hilly and twisty two lane road, but it's a pretty drive with beautiful views from the hilltops. There is a shower and bathroom building, it's very well kept, with a launching ramp in the marina basin. Like Lewis and Clark on the SD side, you do have to have a state park pass or at least a daily pass to drive to the marina. read more
