Road Logistics to Quy Nhon and Phu Yen: Sa Huynh & Tam Quan Rest Stops, Clean Restrooms, and Fuel Stations

The 300 to 410 km overland journey south from Da Nang or Hoi An to Quy Nhon Bay, Ganh Da Dia, and Tuy Hoa links the modern Da Nang – Quang Ngai Expressway with National Highway 1A and the scenic De Gi – Cat Tien coastal road. Knowing the exact locations of clean restroom plazas at the expressway exit, the salt fields of Sa Huynh, the coconut groves of Tam Quan, and the Cu Mong Tunnel corridor lets families with seniors and young children break the drive into comfortable 90-minute stretches.

Across every long-distance South Central charter in our well-maintained 4, 7, and 16-seat fleet, our drivers follow 3 logistical commitments:

1. Planned comfort breaks every 90 – 120 minutes at clean restroom plazas: Drivers stop at verified highway rest areas in Duc Pho, Sa Huynh Beach, Tam Quan coconut town, and Song Cau Bay so your group can use clean restrooms and enjoy fresh coconut water.
2. Full fuel tank before departure and all-inclusive expressway/tunnel tolls: Vehicles depart fully fueled, and your whole-vehicle fare already covers Da Nang – Quang Ngai Expressway tolls, Highway 1A BOT tolls, Cu Mong Tunnel tolls, and parking fees.
3. Flexible choice between the De Gi coastal road and Highway 1A, plus free cancellation 2 hours prior: Depending on your hotel location and weather, your driver can take the scenic oceanfront route via De Gi Bridge, and you can cancel free of charge in advance of your scheduled pickup per agreed trip terms.

4 Key Rest Stops, Clean Restrooms, and Fuel Plazas from Da Nang to Quy Nhon & Tuy Hoa

As your private vehicle travels south from Da Nang or Hoi An toward Quy Nhon Ward in Gia Lai Province and continues into Tuy An Dong Commune and Tuy Hoa Ward in Dak Lak Province, the highway divides naturally into four well-equipped logistical stops:

Primary Rest Stop Hub	Distance from Da Nang / Hoi An	Estimated Driving Time	Restroom, Fuel & Refreshment Facilities	Local Scenery & Specialty Highlights
Stop 1: South Quang Ngai – Duc Pho Junction	Approx. 135 – 150 km (end of expressway)	1 hr 45 min – 2 hrs	Large Petrolimex fuel station, multi-stall clean restrooms, coffee counter, and morning snacks	Smooth transition point between the expressway and National Highway 1A for your first leg stretch

Midday Refreshment Breaks at Sa Huynh Salt Fields and Tam Quan Coconut Groves

When departing Da Nang or Hoi An between 07:00 and 07:30 AM, your private car covers the first 130 km on the smooth Da Nang – Quang Ngai Expressway in just 90 minutes. By 10:30 or 11:00 AM, your group reaches the coastal stretch of Sa Huynh and Tam Quan town. Rather than sitting continuously in the vehicle until afternoon, pausing for 30 to 45 minutes here lets seniors and children wash up, drink sweet Tam Quan coconut water, or enjoy an early lunch of braised Tra River goby fish and sour sea-fish soup.

Because the major Tam Quan highway plazas are built specifically for long-distance tour vehicles, they feature step-free paved walkways, shaded drop-off canopies that shield passengers from sun or rain, and dedicated attendants keeping the restrooms clean throughout the day.

Choosing Between National Highway 1A and the Scenic De Gi – Cat Tien Coastal Road

South of Tam Quan and Phu My, as your vehicle approaches Quy Nhon and Phuong Mai Peninsula, your driver can select between two distinct approaches depending on your destination:

1. The De Gi – Cat Tien Oceanfront Route (Provincial Road 639): Turning toward the sea takes your car across the striking De Gi sea bridge, past turquoise lagoons, white sand dunes, and the Phuong Mai wind-turbine fields directly into Nhon Ly, Ky Co – Eo Gio, and beachfront resorts. This wide, newly paved coastal highway has almost no heavy truck traffic and delivers uninterrupted ocean views.
2. The National Highway 1A – Highway 1D Corridor: Best when heading straight to Phu Cat Airport (UIH), downtown Quy Nhon hotels, or continuing south through the Cu Mong Road Tunnel toward Tuy Hoa. Review direct intercity transfers for this corridor on our Da Nang / Hoi An to Tuy Hoa & Ganh Da Dia Private Car page.

Cu Mong Road Tunnel Tolls, Continuous 4G Coverage, and Digital Payments

Unlike high mountain passes in the Central Highlands where canyon walls can block cellular towers, the entire coastal highway from Da Nang through Sa Huynh and Tam Quan into Quy Nhon and Tuy Hoa enjoys uninterrupted 4G and 5G mobile coverage. At every major rest plaza in Duc Pho, Sa Huynh, Tam Quan, and Song Cau, travellers can pay conveniently by bank card, QR transfer, or cash.

When travelling between Quy Nhon and the Ganh Da Dia – Tuy Hoa coast, our vehicles use the modern Cu Mong Road Tunnel—gliding through the mountain in just 5 to 7 minutes on a flat roadbed rather than climbing the winding old pass—with all tunnel tolls already included in your charter quote. For full route maps across all 7 regional corridors, consult our South Central Vietnam & Central Highlands Road Trip Handbook.
