We are thinking about a picnic here for our anniversary and bringing our bicycles. Would this be a good place for a quiet picnic and a bike ride?

There's a picnic area at the boat ramp, the roads are good for biking but they don't go all the way around the lake.

Trails are good for walking or hiking. Paved road is good for bikes. Not sure about traffic volume.

Picnic yes. However there are no bicycle designated trails, but you could ride along the road.

Yes, for the paved road. For the trails, not so much.

Yes
