At Walking Shadow Ecology, we believe you can enjoy your Yellowstone experience safely - even during the pandemic. 


With some efforts on our part to create as safe an environment as possible, and some flexibility on the part of our visitors, we will all have a safe, memorable time while visiting Yellowstone during COVID-19. 

Our National Park Service-Approved Covid Operating Plan includes:  


  • Installation of a plexiglass barrier between the driver and guests in our spacious Ford Expedition. The front passenger seat shall remain unoccupied. As always, we work to minimize in-vehicle time.  

  • Two 3-layer HEPA air filtration systems run in the vehicle.  

  • While riding in our touring vehicle, all passengers and guide will wear a face mask.  

  • When 6 feet distance cannot be maintained outside the vehicle, we ask that you wear a face mask.  We will provide disinfectant wipes and sanitizer.  

  • We will minimize handling of shared resources.  

  • We will limit our group size to 9 participants per NPS guidelines.  

  • We will honor full refunds due to travel changes specifically related to Covid-19, minus a $40 booking fee.  

  • Safety is always at the forefront of our experiences, and we appreciate your assistance in keeping you, our guides, and forthcoming participants safe.
