Antelope Island was originally owned by The Church of Jesus Christ of Latter-day Saints, then John Dooly Sr until 1969 when the state of Utah purchased the Northern part of the island. In 1981, the state purchased the remainder of the island where the historical Fielding Garr Ranch established in 1848 is located and formed Antelope Island State Park.
You enter the park from Syracuse taking the 127 to the 7 mile causeway that crosses the Great Salt Lake viewed from a window in the visitor center in the photo above. The mass of land you see jutting out from the causeway on the left in the above photo is a veteran memorial and beach area with parking.
The visitor center also offers some great views and statues of bison and antelope that can be found in the park. The below photos were taken near the visitor center parking lot.
After the visitor center, I recommend heading to the Buffalo Point Trailhead. The trail is all uphill but offers some great views on the way up and 360 degree views once you reach the top along with some interesting rock formations. Below are a couple of photos I took. The first photo is looking towards White Rock Bay on the way up the trail and the second photo is looking towards Bridger Bay at the top of the trail.
After the trail on your way out of the park, get back onto Antelop Island Road and take it all the way to Fielding Garr Ranch. The Church of Jesus Christ of Latter-day Saints owned the ranch and island from 1848 to 1870 when John Dooly Sr. purchased both. He established the Island Improvement Company which managed the ranch and island until the state of Utah purchased the Northern part of the island in 1969 and then the remainder in 1981 at which point the it was turned into the state park it is today. Below are some photos taken at the ranch. You can also view my video walk-through on my YouTube channel here: https://www.youtube.com/watch?v=KeMfhRNS6DY
While on your way to and from Fielding Garr Ranch keep an eye out for bison as it's along this stretch of road where you are most likely to see them. Below are some photos I took along this road.
