One of the first things you’ll notice about Idaho is how unspoiled it is. This is a state with over 60% of the land reserved for the public, with huge parks, forests, protected wilderness and the aforementioned mountains. All of which means it’s a delight to drive through, with vistas of staggering beauty.
Many visitors start in the south of the state, where the busiest towns and cities are. That includes state capital Boise in the south-west, which is linked to Twin Falls by the I-84, which exists the state west to Oregon and South to Utah. Driving east from Twin Falls you can leave the I-84 and join the I-86 for American Falls and Pocatello.
At the latter, you’ll find the I-15 interstate which runs south to north through the east of the state. Again, to the south it leads to Utah but follow it north for Blackfoot, Idaho Falls, Dubois and onwards to Montana.
Speed limits in Idaho vary by area, with limits of 20mph in school zones moving up to 80mph on rural stretches of interstates. Freeways in urban areas have a limit of 65mph. You’ll be driving on the right, overtaking on the left and seatbelt use is compulsory for all. Our branch teams can answer any other specific questions you may have.
There are plenty of stunning scenic drives to enjoy in Idaho, most notably along US93. Here you’ll skirt the banks of the Salmon river, past endless mountains until you reach Sun Valley, a popular ski resort. Along the way you’ll pass small towns full of local charm. Alternatively, explore the Sawtooth Scenic Byway, a three-hour drive along the Idaho 75 road.
From Shoshone in south of the state you’ll head into the Sawtooth National Forest, past Cathedral Pines and on to Stanley. There are myriad places to park up and camp, hike, fish, ski and raft. There are lots of hot springs to relax in too, plus ranches and log cabins serving up barbecue all year round.
This state’s natural beauty means it’s a place for those with a love of wilderness, of bracing air and outdoor activity. Hundreds of miles of mountain make it a popular ski location, while the forests and parks will truly leave you with a sense of a majestic American state stretching towards the clear sky.
The state’s largest city – and its capital – Boise is something of an outlier in Idaho. Whereas pretty much every other town feels rustic and happily lost in time, Boise is definitely modern and buzzing. The downtown has fine restaurants and pedestrianised areas to explore on foot, while its position next to some of the ubiquitous mountains means it’s a fabulous base for hikers to set off from.
In summer, float down the Greenbelt River in a tube, close to Julia Davis Park which hosts some fine museums. Boise also has a large Basque population, many of whose ancestors arrived in the early 20th century to be shepherds here. Their pride is encapsulated in the Basque Museum, but also in superb ethnic restaurants such as the highly rated Bar Gernika, the perfect place for chorizo, beef tongue and croquetas.
Where’s the mountains and water, there’s also waterfalls, and many of the state’s most beautiful areas are located close to these. Idaho Falls is quite a large town, with zoos and museums, great cafes proximity to brilliant outdoor activities. From here you can access Yellowstone National Park and the Craters of the Moon monument and lava fields.
Twin Falls sits on the Snake River, perfect for kayaking. Cross the canyon on the incredible Perrine Bridge then gasp in awe at the Shoshone Falls. At 212 feet high they dwarf even Niagara Falls.
Idaho has played its part in the grander tapestry of American history, with Lewis and Clark exploring here, key parts of the Oregon Trail and the gold rush running through here too. The neighbouring towns of Sun Valley and Ketchum simultaneously embrace that past while attracting tourists for their modern offerings too.
The Dollar and Bald mountains cast a shadow over both, which is why these are some of the most popular skiing and winter sports destinations in the entire US. Snowboarding, heli-skiing, snowmobiling and more beckon, while you can also go rock-climbing, skating, fish or just relax in the hot springs. There’s history here too, with museums shedding light on the town’s mining origins, with original ore wagons on display.
From marvellous mountains to bubbling hot springs, handsome towns to dramatic waterfalls, car hire in Idaho is your key to unlock this naturally beautiful state.
To hire a car with Hertz in Idaho, you need a valid driver’s licence (held for at least a year), any required international driving permits, a valid passport/ID card (no photocopies), and a credit card in your name to cover the rental cost and pre-authorisation amount. If you booked with a different card, bring that one, too. All cards must be in the driver’s name.
Age requirements vary by country. Please check the Rental Qualifications during booking for specific details. At Hertz, we ask the driver’s age to determine if a young driver fee applies. In most cases, the driver must be at least 25 years old and have had their license for at least 1 year. Drivers under 25 usually incur an additional fee.
As per Hertz policy, the booking MUST be made under the name of the renter i.e. main driver who picks the car up with his/her own debit* or credit card, using a debit* or credit card in the renter's name. The same debit* or credit card MUST also be presented upon collection of the vehicle, as a guarantee. Hertz does NOT accept debit* or credit cards in a name other than the main driver's, even if accompanied by a "per procurement"/mandate document and personal documents of the debit or credit card holder. *HERTZ do NOT accept debit cards in every country. Please check Debit/prepaid Cards for details.
Hertz car rental rates exclude fuel. Cars are provided with a full tank and must be returned with a full tank, or a refuelling charge will apply. You can purchase fuel at rental, but no refund is given for unused fuel. Ask about our Fuel Purchase Option (FPO) when picking up the car.

However, no-shows without cancellation will incur a No Show/Lost Rental Fee.
