So named due to the still-standing aqueduct that carried the original Erie Canal—Clinton's Ditch—over "Mud Creek" (part of Ganargua Creek), Aqueduct Park is a treasure trove for Canal buffs. For starters, the aqueduct itself is quite a sight. Modern Lock 29 is also here, for those who like to watch boats lock up and down. There's a man-made waterfall where the modern canal spills over into the creek. Also here is the historic Aldrich Change Bridge; though it no longer crosses the canal, it was built when the original canal was widened in 1840 (the widened canal allowed no room for the south-bank towpath through the village of Palmyra, so the bridge was needed for the mules to change sides).
The farm property has been restored to resemble what it would have looked like in 1830. You can start at the welcome center, with an introduction to the history of Joseph Smith's family and views of the whole farm complex. The Smith Frame Home (1825) still stands, and a replica of the 1818 Smith Log Home is nearby. Free guided tours daily.
The exact spot where Smith received his first vision is not known, but it was somewhere within the woods west of the farm. What is left of the grove is maintained by the church, open and free to anyone who wants to walk its trails. No guided tours.

Even though Smith had moved away to Pennsylvania in 1827, it was at Egbert B. Grandin's print shop that the first edition of the Book of Mormon was printed in 1830. Today, the restored print shop houses a press, bindery, and even the shop where the first Book was sold. Free guided tours daily.
Despite being the location of the church's founding, no temple was built in the area until the year 2000. Even then, it was the first such Temple built in the entire state. Keep in mind that only members of the Church of Jesus Christ who are in good standing with the Church are permitted inside the Temple itself. The beautifully maintained grounds and gardens, however, are open to all.
