One of my preferred rest stops when traveling, has a perfect area for your dogs to go potty as well as a nice open area with restrooms, awesome views

Very nice rest area. Bathrooms are kept clean. The outside is also kept clean and there is even a snack bar that is open occasionally. The view of the lake is awesome. Just watch where you walk because not everybody cleans up after their pets.

Great place to rest, stretch your legs, and play for a bit with kids/pets while enjoying an amazing view 😄

Small but nice stop. Dog friendly. Picnic tables and grass under shade out back.

Great spot to sleep in a vehicle. Was quiet and had a peaceful few hours nap. Currently no I side restrooms (port a potties that were ok as far as they go). Great view though-parking faces sunrise so be prepared. Not sure if there are more issues as we were only here from 3am-6:30am. Not sure what all the classic Chevy Vans were about...
