Zion National Park

Zion is the closest of the great Utah parks to Las Vegas — about 160 miles and 2.5 to 3 hours up I-15 through the Virgin River Gorge — and the drama is vertical: 2,000-foot sandstone walls over the Virgin River, with Angels Landing's chain-assisted ridge and the wade-through slot of The Narrows as its signature hikes. Entry runs $35 per vehicle for seven days (under-16s free), and since January 2026 non-US visitors 16-plus pay a $100-per-person surcharge on top — waived with an America the Beautiful or annual pass. The park itself never closes.

The logistics decide the day. During shuttle season — March 7 to November 28 in 2026 — private cars are barred from the Zion Canyon Scenic Drive: you park at the visitor center or in Springdale and ride the free shuttle, and midday lines get real. Angels Landing requires a permit won by lottery ($6 application plus $3 a person) — you cannot walk up and hike it — while the bottom-up Narrows needs no permit but closes whenever the river runs high, including summer monsoon flash-flood days. Summer canyon heat tops 100°F, so hike early; spring and fall are the sweet spots; winter hands the scenic drive back to private cars. One more trap: Utah runs an hour ahead of Vegas — set out earlier than the clock suggests.
