Michel Lagneau

Yosemite Airlines, California through the valleys

Yosemite Airlines linked the California coast with Yosemite National Park in the late 1970s. Michel Lagneau turns those services into a scenic route around valleys, ridges and fields near the park.

The direct GPS line is not the goal. The pleasure is in intelligent detours: follow terrain, keep a reasonable altitude, spot Half Dome and arrive cleanly at small fields.

NavigationScenic

GPS helps, but valleys guide the flight.

Understanding the flight

The article keeps the spirit of tourist service: the goal is not only reaching a field, but making the park readable from the cockpit.

Half Dome becomes a central visual reference. It should be part of the flight even though it is not an airport.

Before departure

  • Prepare altitudes before entering the Sierra Nevada.
  • Fly with good visibility to enjoy the terrain.
  • Do not blindly follow the GPS line: route around ridges if needed.
  • Keep speed reasonable for small strips and valley approaches.

Experience tips

Keep the itinerary flexible: a visual detour is better than an unrealistic straight line.

The flight is prettier early morning or late afternoon, when terrain stands out clearly.
