What is actually visible out there

The Milky Way arcing over Antelope Island above the tour van.

The Milky Way

From roughly April through October, arcing up out of the south. This is the headline and it’s why the summer departures book out. From a site this dark the galactic core has structure. You can see the dark rift running through it. Most visitors from cities have never seen this and the reaction when it resolves is consistently the best part of the guide's night.

Planets

Whichever are up. Jupiter and its four Galilean moons are visible through binoculars and are usually the first thing that convinces people the sky is worth the drive. Saturn's rings, when it’s well placed, do the rest. Venus, Mars and Mercury come and go with the season.

Meteor showers

If you time it. The Perseids peak around 11–13 August and are the reason August evenings sell first; the Geminids in mid-December are technically richer but the island is bitterly cold then. The Quadrantids, Lyrids, Orionids and Leonids all produce good nights out here.

Stargazers under the island's night sky, where the guide's optics come out.

Deep-sky objects through the guide's optics: the Andromeda Galaxy, the Ring Nebula, the Double Cluster, the Great Globular Cluster in Hercules. And, unexpectedly for many people, the lake itself: on a still night the water goes glassy and reflects the sky, and the bison are audible in the dark somewhere out on the grass.

What to wear: you’ll be colder than you expect

This is the single most common mistake on this tour. You’re standing still, outdoors, after sunset, on an exposed island in the middle of a lake, for an hour and a half. Whatever the daytime temperature was, subtract a lot. Even in July it can drop into the fifties out there with wind, and people who came out in shorts spend the program in the van.

Every season
A warm layer more than you think you need, long trousers, closed shoes, and a hat.
Autumn and winter
A proper insulated coat, gloves, and something over your ears.
Late spring
Insect repellent for the gnats.
A red flashlight
Bring one if you own it, or put red cellophane over a phone flashlight. White light destroys your night vision and it takes about twenty minutes to get it back, which is most of the program. Your guide will ask you to keep phones dark for this reason, and it’s worth cooperating with.
Binoculars
More useful here than people expect. A cheap 10x50 pair shows you Jupiter's moons and the Andromeda Galaxy.

Do not bother bringing your own telescope. The guide brings optics and knows the sky; a strange instrument in the dark is a frustrating way to spend the evening.

Timings and how the evening runs

Pickup is from selected downtown Salt Lake City hotels and the drive out is about 45 minutes, roughly 41 miles up I-15 and then across the seven-mile causeway onto the island. The causeway at night is a strange and good piece of the experience in itself: water on both sides, no lights, nothing ahead.

On the island you get a 90-minute guided night-sky program, then the return drive. Start times move through the year to follow astronomical darkness: 8:00 PM pickup from May to early September, 7:30 PM from September to mid-October and again from mid-March to May, and 6:30 PM from mid-October to mid-March. Door-to-door the tour runs about four and a half hours.

Groups cap at fourteen. Departures run seven nights a week in season. Solo travelers are welcome to book; we just can’t run a departure for a single guest, so if nobody else takes your date we’ll move you to another night or refund you.

Salt Lake Antelope Island Dark Sky Experience: your questions answered

Can you really see the Milky Way from Antelope Island?

Yes, from roughly April to October, on a clear night when the moon is down or close to new. Antelope Island State Park has been a certified International Dark Sky Park since 2017 and the water on all sides puts real distance between you and the Wasatch Front light dome. The galactic core rises in the south and on a good night shows visible structure to the naked eye.

What happens if it’s cloudy?

We watch the forecast and contact you rather than drive you out to look at an overcast sky. This tour is explicitly weather-permitting. If your night is called off we’ll rebook you onto another evening if your dates allow, or refund it.

Does the moon affect what we’ll see?

More than anything else. A bright or full moon washes the Milky Way out entirely and dims most deep-sky objects. If your dates are flexible, book within about ten days of new moon and you’ll see a dramatically better sky. Ask us when you book your tour and we’ll tell you what the moon is doing on your dates.

What time does the tour start and finish?

It follows astronomical darkness through the year. May to early September: 8:00 PM pickup, back around midnight. September to mid-October and mid-March to May: 7:30 PM pickup. Mid-October to mid-March: 6:30 PM pickup, back around 10:30 PM. The night-sky program itself runs 90 minutes and the whole tour is about four and a half hours.

Do I need to bring a telescope or binoculars?

No. Your guide brings optics and runs the program. If you own a pair of binoculars, bring them; even a modest 10x50 pair will show you Jupiter's moons and the Andromeda Galaxy, and having your own is more rewarding than queuing for an eyepiece. Leave a personal telescope at home; setting up an unfamiliar instrument in the dark is a frustrating way to spend the evening.

How cold does it get?

Colder than you expect in every season. You’re standing still on an exposed island with wind coming off the water. Summer nights can drop into the fifties Fahrenheit; winter nights are far colder. Bring one more warm layer than seems necessary, plus a hat. It’s the most common regret on this tour.

Is the stargazing tour suitable for children?

Yes for children who can stay up, stay warm and stay quiet for a 90-minute program, and it’s often the thing they remember from the whole trip. Less so for very young children, given the late finish. Children must be accompanied by an adult and reduced child fares apply.

Does it run in winter?

Yes. Departures run from mid-October to mid-March with a 6:30 PM pickup, and winter is when the air is driest and the sky most transparent. Orion and the winter Milky Way replace the summer galactic core. It is cold and exposed, so dress properly, but many of our guides consider these the best skies of the year.
