Saguaro National Park — Interstate Access, 2026 Fees & Truck Notes

01 Park overview

Saguaro is two parks under one name (the Rincon Mountain District (East) and the Tucson Mountain District (West)) separated by 30 miles of Tucson urban area. Both protect dense stands of saguaro cactus, the iconic columnar cactus that grows only in a small slice of the Sonoran Desert and lives 150-200 years. The East District is larger (67,000 acres), wilder, and includes Mica Mountain at 8,664 ft; the West District is smaller (24,000 acres) but has the densest saguaro stands. From I-10 the standard access for the East District is Exit 275 (Houghton Rd), 10 mi to the visitor center. The West District is reached from I-10 Exit 242 via Avra Valley Rd to Sandario Rd, about 22 mi. A single $25 entry covers both districts for 7 days.

Saguaro cactus lives 150-200 years; first arms typically appear at age 70-100

2026 nonresident fee — does not apply here

Fee-free days available for U.S. residents only beginning January 1, 2026.

08 FAQ

How do I get to Saguaro from I-10?

For the East (Rincon Mountain) District: I-10 Exit 275 (Houghton Rd), then 10 miles north and east via Old Spanish Trail to the visitor center. For the West (Tucson Mountain) District: I-10 Exit 242 (Avra Valley Rd), then 22 miles via Sandario Rd to the visitor center.

Which district should I visit?

The West District has the densest saguaro stands and is closer to downtown Tucson; the East District has more elevation, more trails, and a longer paved loop drive. Most visitors with a half-day pick West; with a full day, both are doable in one trip.

Does the $100 nonresident fee apply?

No. Saguaro is not on the 2026 NPS nonresident-surcharge list. The standard $25 vehicle fee applies to all visitors.

Can I camp inside the park?

No drive-up campgrounds. The East District has six backcountry sites accessible only by 5+ mile hikes (permits required). RV camping is at Tucson-area state parks and the Tucson/Lazydays KOA on the east side.
