Skamania Lodge is approximately 45 minutes east of Portland International Airport along Interstate 84 East which parallels the south bank of the Columbia River. There is not a hotel shuttle or scheduled public transportation.
A rental vehicle or ride hailing service may be the best options. You might consult Uber or Lyft for approximate pricing given the time and distance of a one-way trip.
For past workshops, we have had some success coordinating ride share trips for attendees with similar flight arrival times. More details to be posted about that option soon.
