The Subway in Zion National Park: Permits, Safety, and Trail Guide

The Subway is one of Zion National Park’s most sought-after hikes—and for good reason. With its surreal tunnel-shaped canyon, cascading waterfalls, and mossy emerald pools, it feels like you’ve stepped into another world. But this isn’t your average hike—it requires a permit, solid preparation, and a good sense of adventure.

In this comprehensive guide, we’ll cover everything you need to know before attempting The Subway—from how to get a permit to what gear you’ll need and what to expect on the trail.

What Is The Subway in Zion?

The Subway is a slot canyon in the Left Fork of North Creek, located in the park’s backcountry. Its nickname comes from the cylindrical, tunnel-like section where the walls curve inward, resembling—you guessed it—a subway tunnel.

There are two main ways to explore The Subway:

• Top-Down Route: Technical canyoneering adventure requiring rappelling and swimming.
• Bottom-Up Route: Non-technical but strenuous hike requiring boulder scrambling and wading.

Subway Permits: How to Get One

A permit is required year-round for both routes. Here’s how to get one:

1. Advance Lottery (Recommended)

• Apply 2–3 months ahead of your desired date
• Lottery opens on the 5th of each month
• Results released on the 25th

2. Last-Minute Drawing

• Apply 7–2 days before your trip
• Great for spontaneous trips, but limited availability

3. Walk-In Permits

• Available at the Zion Visitor Center the day before your hike
• Risky during peak season—only a few are released

Pro Tip: Apply for weekdays if you want better odds.
