Most pools are built for lounging. Stadium Swim at Circa Resort & Casino is built for watching, and that's why it works in every month of the year. Circa bills it as the only year-round pool amphitheater in Las Vegas, and in winter the water is heated. It's a sports bar you can swim in.
A 143-foot screen and room for 4,000
Circa's Stadium Swim - Adults Only (21+) stacks six pools in tiers facing one screen, 143 feet across and 40 feet tall, above Fremont Street in Downtown Las Vegas. Capacity is 4,000. On a football Saturday the whole amphitheater groans at the same missed field goal, in the water. That's the experience. The screen carries pro and college football, Golden Knights hockey and fight nights, and Circa's sportsbook is downstairs.

Where: Circa Resort & Casino, Fremont Street, Downtown Las Vegas. Ages: 21 and over. Booking: general admission. Best for: sports fans, bachelor and bachelorette groups, and anyone who wants a pool day with a game on.
Winter at Stadium Swim
From November 1 to February 28, Circa runs its winter season: the pools are heated to 94 degrees, the hot tubs to 100, and the cabanas get heaters and robes. December highs in Las Vegas average about 57 degrees, so the steam off the water is part of the picture. Football season and pool season overlap here. Robes on, game on.
Who should pass
This is a loud room. Anyone after a quiet pool and a novel will be happier at a resort pool on the Strip. It's a crowd, by design. General admission also means chaise lounges, not the reserved seats closest to the screen.
The bottom line
Book it for the game. For a group in town on a football weekend, Stadium Swim is the best seat downtown that isn't in the sportsbook. There's a security check at the entrance. Our Mob Museum guide covers the best way to spend the morning a few blocks away.
