I went to Las Vegas in June, which is either the best time or the worst time depending on your relationship with triple-digit heat and the specific kind of sensory overload the Strip produces at full summer capacity. I came down on the side of best time, mostly because the heat makes everything feel appropriately extreme.
The Strip at night is one of the more genuinely strange urban environments on earth. The scale of the casino hotels — Bellagio, Wynn, MGM Grand, The Venetian — exceeds anything that should be possible in a desert that didn't have much water to spare. The Bellagio fountains run every fifteen to thirty minutes, choreographed to music, shooting water six stories into the desert air. You stand at the rail with hundreds of strangers and watch it and it works every time.
What I didn't expect was the food. The concentration of serious restaurants inside the major casino hotels — driven by celebrity chef residencies that started in the late 1990s and accelerated from there — means the dining options are genuinely exceptional if you're willing to pay. The Cosmopolitan and Wynn properties in particular have restaurants worth flying in for.
The desert around Las Vegas is equally underappreciated. Red Rock Canyon is 20 minutes from the Strip and belongs to a completely different world: sandstone towers, hiking trails, climbing routes, the Mojave at its most dramatic. After a few days of casino air and artificial light, that drive west into the canyon is exactly the reset you need.
