Planet WalkPurelyPA! Pluto may no longer be a planet, but it’s still a fun place to visit – if you are on the “Planet Walk” in Allentown’s beautiful Lehigh Parkway.

Here a stroll on the bridle path along the Little Lehigh Creek becomes an interplanetary expedition. A series of educational signs represent our solar system. The sun and the planets have been installed to show their relative distances apart – Mercury, Venus, Earth and Mars fairly close together and the rest of the planets really spread apart – and you can cover the whole trip (at one foot equals one million miles) by walking just three-quarters of a mile.

Thanks to the Lehigh Valley Amateur Astronomical Society, space travelers of all ages can get a real sense of the vastness of our solar system, and take in one of the city’s best public parks at the same time.

Here are directions to the Planet Walk from the society:
Enter the Little Lehigh Parkway from 15th Street in South Allentown (also called Jefferson St.). About one mile into the parkway, you will reach a steel bridge with a white house to the left and a parking lot to the right. Park in the lot and walk toward the water, where you’ll see a sign pointing along the Bridle Path and taking you under the steel bridge. Here you will find the beginning of the Planet Walk with the inner Solar System including the Sun, Mercury, Venus, Earth and Mars. The first post is for the Sun.
