Established: International Dark Sky Park (Bronze tier) since 2017.

## Overview
Antelope Island floats in the middle of the Great Salt Lake, connected to the mainland by a causeway, and its open, treeless terrain gives a 360-degree horizon rare so close to a major metro area. It was Utah's first Bronze-tier International Dark Sky Park, just a short drive from Salt Lake City.

## What to see
Milky Way over the Great Salt Lake and, unusually for a spot this close to a metro area, occasional views of aurora on active geomagnetic nights.

## Highlights
- One of the closest true dark-sky sites to Salt Lake City
- Reflective salt flats and lake surface add contrast to night photography
- Free ranger-led dark sky programs held periodically

## Tips
- Causeway entry fee applies — check current rates before you go
- The lake's brine flies and gnats can be intense near the shoreline in summer
- Bison roam freely on the island — keep a safe distance, especially in the dark
