3. How to Get There

By Car

Starting Point	Approx. Distance	Suggested Route
Phoenix, AZ	~ 240 km (150 mi)	Take I‑10 E toward Tucson, merge onto US‑95 N at Benson, then follow local signs to Cactus Flat.
Tucson, AZ	~ 150 km (93 mi)	Head north on I‑10 W to US‑95 N, then turn onto AZ‑86 W toward the small community of Hereford. From Hereford, follow the paved county road (CR‑15) eastward for ~ 30 km to the dam site.
Yuma, AZ	~ 260 km (162 mi)	Travel east on I‑8 E to AZ‑85 N, then connect to US‑95 N and follow the same directions as above.

Parking: A small, unpaved pull‑out area sits just off the main access road. It’s large enough for a couple of cars and a modest picnic setup. No fees are charged, but the surface can become dusty during dry periods, so a high‑clearance vehicle or a spare tire is advisable.

Public Transportation

Public transit options to Cactus Flat are limited. The nearest major bus hub is in Sierra Vista, about 60 km (37 mi) north. From there, you’ll need a rental car or rideshare service to reach the dam.

Flying In

The closest commercial airport is Sierra Vista Municipal Airport (FHU), which offers regional flights to Phoenix and Dallas. From the airport, rent a car and follow the directions above.

5. What to Expect

• Scenic Views: From the dam’s crest you can see the endless expanse of Cactus Flat, the distant Huachuca Mountains, and the subtle ripple of the reservoir below. Sunrise paints the sky in shades of pink and gold, while sunset turns the water a deep amber.

• Quiet Atmosphere: Unlike larger, tourist‑heavy reservoirs, Riggs Reservoir Dam remains largely untouched. Expect minimal foot traffic, allowing you to enjoy a true sense of solitude.

• Wildlife Spotting: Keep an eye out for desert‑adapted birds such as Gila woodpeckers, cactus wrens, and occasional red‑tailed hawks soaring overhead. Small mammals like jackrabbits may appear at dusk.

• Recreational Activities: The reservoir is shallow, making it unsuitable for boating, but it’s perfect for picnicking, photography, and short nature walks along the perimeter. Bring a sturdy pair of shoes for exploring the surrounding scrubland.

• Facilities: There are no restrooms, vending machines, or concession stands on site. Pack all necessities—water, snacks, sunscreen, and a trash bag for leave‑no‑trace cleanup.

7. Travel Tips

1. Bring Plenty of Water – The desert climate can be dehydrating, even in cooler months. Carry at least 2 L per person.
2. Check Road Conditions – Some access roads are unpaved and may become slick after rare rainstorms. Call the Cochise County Road Services (555‑123‑4567) before heading out.
3. Sun Protection – A wide‑brimmed hat, UV‑blocking sunglasses, and high SPF sunscreen are essential year‑round.
4. Leave No Trace – Pack out all trash, and avoid disturbing the native vegetation. The area’s fragile ecosystem depends on responsible visitation.
5. Timing for Photography – The “golden hour” (30 minutes after sunrise or before sunset) provides the most dramatic lighting for the dam’s concrete surfaces and the surrounding desert.
6. Cell Service – Coverage can be spotty; download offline maps (Google Maps or Maps.me) beforehand.
7. Safety First – The dam’s edge can be steep. Keep children and pets supervised, and avoid climbing onto the spillway.
