Lagoon Amusement Park in Farmington, Utah, is closing out its 2026 summer stage season this weekend, with final free performances of its day and night shows listed through Monday.
If the Carousel Theater shows are part of your trip plan, the traveler decision is immediate: aim for Sunday, August 16, for the last Z’s Emerald Underground night performances, and Monday, August 17, for the last Smoke and Mirrors day performances, then recheck hours and showtimes before you leave.
- Park: Lagoon Amusement Park in Farmington, Utah.
- Day show end: Smoke and Mirrors listed through August 17, 2026.
- Night show end: Z’s Emerald Underground listed through August 16, 2026.
- Cost: Both shows are free with park admission.
- Where: Carousel Theater inside Lagoon.
Lagoon’s official Events and Shows page is the primary schedule source for the end dates and daily time grids. Deep Arrival treats that page as the binding surface for this weekend’s planning, not social posts or older seasonal roundups.
The shows sit inside ordinary paid admission. You do not buy a separate theater ticket for either production, which matters if you are comparing a show-focused day against a pure ride day.
What ends this weekend
Smoke and Mirrors: Birthplace of the Impossible is Lagoon’s signature day magic show. The official listing runs May 23 through August 17, 2026, at Carousel Theater.
Showtimes are 12:00 p.m., 1:30 p.m., and 3:00 p.m. on Wednesday through Monday, with Tuesdays off. Monday, August 17, is the last listed day-show date on the current schedule.
Z’s Emerald Underground: A New Underground Awaits is the night production. The official listing runs May 30 through August 16, 2026, at the same theater.
Night showtimes are 5:30 p.m., 7:00 p.m., and 8:30 p.m. on Tuesday through Sunday, with Mondays off. Sunday, August 16, is the last listed night-show date on that board.
A Monday-only visit can still catch Smoke and Mirrors. It will miss Emerald Underground after Sunday’s final night grid ends.
How to sequence a final show day
A Saturday visit on August 15 can still cover both productions if park hours and energy allow. The home page currently shows Saturday open 10 a.m. to 10 p.m., which supports a full day-show and night-show stack.
Sunday, August 16, currently lists 10 a.m. to 9 p.m. That shorter evening window still supports day and night shows, but leaves less cushion after the final 8:30 p.m. performance.
Monday, August 17, currently lists 10 a.m. to 9 p.m. as well. That day still carries the final Smoke and Mirrors grid after Emerald Underground is finished.
Build the day around the theater first, then fill ride gaps. Carousel Theater is a fixed place on the property, so arriving early enough to claim seats for a preferred showtime is more reliable than treating the show as a walk-up afterthought at peak afternoon crowds.
Families with young children may want the noon or 1:30 p.m. Smoke and Mirrors slot, then a quieter mid-afternoon break before any night show attempt. Guests focused on coasters can reverse that order only if they accept a higher chance of a full theater when they arrive later.
What does not change with the show calendar
The end of the summer stage pair does not mean the park closes. Lagoon continues to sell tickets, operate rides, and publish daily hours after the shows leave the schedule.
Use Deep Arrival’s live Lagoon park guide for the broader property layout, and the Lagoon height requirements page if children in the group need ride eligibility checked before you commit to a long day.
The Lagoon park map remains useful when you want the Carousel Theater relative to parking, food, and major coasters. Pair that map check with same-day hours on Lagoon’s own site, because weather and operating decisions can still shorten an evening even when a show remains listed.
Pioneer Village and Lagoon A Beach follow their own seasonal patterns. Do not assume every summer amenity stays aligned with the theater calendar after the stage pair ends.
Tickets, timing, and who should prioritize this weekend
Guests who specifically want the 2026 summer stage programming should treat this weekend as the last clear window. After Monday, the official Events and Shows page no longer lists this dual-show summer pair.
Season Passport holders and single-day ticket buyers face the same show calendar. The free-with-admission rule does not create a separate show pass, so the real constraints are park open hours, travel time from the Salt Lake Valley or Wasatch Front, and how many showtimes you can realistically attend without rushing children or older guests.
If your only free day is after August 17, reframe the trip as a rides and Pioneer Village visit rather than a theater visit. That is a different day shape, not a failed show day, once the summer productions leave the board.
Out-of-town visitors who already hold nonrefundable hotels near Farmington or Salt Lake City should still recheck the show page before shifting the entire trip. The park remains open; only the summer stage titles drop from the listed entertainment board.
What comes next after the summer shows
Lagoon’s later-season contrast is Frightmares. The park’s Frightmares page lists the 2026 event opening September 11 and running through November 8, with notes that dates, times, and shows can change. Visit Salt Lake also carries a 2026 Frightmares event listing for regional trip planners comparing late-summer and fall park nights.
That residual calendar matters if you are choosing between a late-summer show push this weekend and a fall evening visit later. Frightmares is not a substitute for Smoke and Mirrors or Emerald Underground; it is a different seasonal product with its own rules and hours.
Between Monday’s final day show and the September Frightmares open, plan any mid-to-late August visit around rides, water attractions when open, and published park hours rather than the summer theater grid. That gap is ordinary summer park operation, not a second theater season on the same Events page.
Visitors who dislike haunted events can ignore Frightmares entirely and still use Lagoon on non-event days later in the year when the park publishes those hours. The key this weekend is only whether the summer stage pair is still part of your reason to go.
| If you… | Do this |
|---|---|
| Want both shows this weekend | Visit Saturday or Sunday; lock theater times first. |
| Can only go Monday, August 17 | Plan for Smoke and Mirrors only; night show is done. |
| Miss both end dates | Switch to rides and recheck hours; no summer stage pair remains. |
| Prefer fall evenings instead | Watch Frightmares from September 11 with separate rules. |
| Travel with height-sensitive kids | Check ride heights before buying a long show-plus-ride day. |
- This weekend: Final dual-show window for the listed 2026 summer pair.
- Sunday night: Last Emerald Underground performances on the current board.
- Monday day: Last Smoke and Mirrors performances on the current board.
- After Monday: Plan rides and hours, not these summer stage titles.
- September: Frightmares begins September 11 under separate event rules.
Confirmed facts in this report come from Lagoon’s opened Events and Shows page, current hours shown on the park site, and the Frightmares schedule page. Show content descriptions on the official page are promotional copy; Deep Arrival does not treat them as timed performance guarantees beyond the listed dates and showtimes.
Unknowns still include weather holds, last-minute theater changes, and whether Lagoon will post a different interim entertainment slate after August 17. Recheck the official shows page the morning you travel if the theater is the main reason for the trip.
