I look for scenic view turnouts, historical markers and old type rest stops (before the interstates). Many of these are on the water. The old rest stops are about 50 miles apart along older highways.
Much of that area is state and federal forest. Hunters make access during the season, but will be vacant in summer. Much of this land is thick wilderness. Do not wander out of sight without gps.
In many places, access is provided for boat launching and even paved walkways in nature areas. even bike trails will have parking areas for access.
Areas around river mouths will have parking and services for massive numbers of fishermen, but little traffic in summer.
