I’ve taken many tours in my life, but this was by far the most I’ve learned in an 8 hour period. Our tour guide, Peter, is an amazing communicator with an off-the-cuff charm. A native Portlander, Peter did not regurgitate information from guide books, but had in-depth scientific and historical knowledge of the land - from geology, botany, and biology to the culture and human history of this area. I was thoroughly impressed.
If you’re a science buff, I guarantee you that you will not find a more interesting tour.
He was also very helpful at each stop, making sure that we knew all the choices available. The tour felt flexible and unrushed. I brought my parents, who are non-native English speakers and they also just loved it.
