What Travellers Say
Reviews Summary
Visitors generally praise the Carl Sagan Planet Walk for its educational concept and the engaging audio tour narrated by Bill Nye. It's seen as a unique way to understand solar system scale, though some find navigation challenging after the initial planets and note occasional wear and tear on the markers.
"We enjoyed walking to all the planets. The ending near Neptune and Pluto, however, was a little sketchy."
Christine G
"The Sagan Planet/Space Walk is a scale model of our solar system. Starting with the sun, you can scan a QR code, follow arrows on the monuments, and/or dial into a phone tour narrated by Bill Nye. Youβll end up walking through some beautiful neighborhoods with bookshops and cafes to explore, parks, etc. It is very much worth the time, especially if the weather is nice. Follow the planets and then head to one of the many gorge trails!
I will only post photos of the very beginning of the walk with the Sun and Mercury"
Evan Smith
"Earth, the GOAT of planets. While the marker does not specifically mention Earth holding the records for Most Humans in One Location, Largest Corn Harvest in the Solar System, Most Super Bowl Winning Teams, and many more well deserved accolades, it all goes without saying. Earth rules, as does its marker on the planet walk. Go pound sand, Neptune. Avoid the crowds and show up early."
