Why rent a car in Boulder?

Boulder is tucked in the foothills of the Rocky Mountains, 25 miles northwest of Denver in the US state of Colorado. Located 5,430 feet above sea level, it overlooks the dramatic sandstone slabs of the Flatirons.

Stroll down Pearl Street Mall for shops and cafés, or go hiking along one of the city’s 200 miles of trails. Nearby attractions include the National Centre for Atmospheric Research, a museum of weather and global warming, and the Eldorado Canyon State Park, famous for its technical rock-climbing routes.

To best explore the mountainous landscape in the rest of Colorado, you’ll be glad to have a rental car in Boulder for your day trips.

How to get to and around Boulder?

Flights arrive at Denver International Airport, and highway 36 gets you to Boulder in less than an hour. Denver is 35 minutes southeast, where the architecturally stunning Denver Art Museum holds the world’s greatest collection of Native American art as well as western art objects. Visit also the Molly Brown House Museum, the Victorian mansion house of ‘unsinkable’ Molly Brown, an American philanthropist and socialite who survived the sinking of the RMS Titanic.

East of Denver, 40 minutes from Boulder, is Aurora, normally a quiet suburb with a low crime rate, which made the world media’s headlines in July 2012 for the mass shooting during a screening of the Batman movie ‘The Dark Knight Rises’. Aurora has more than 100 parks, 50 miles of trails, six public golf courses and two beautiful reservoirs.

A great hiking trail in Boulder County is on Rabbit Mountain between Longmont, half an hour northeast, and Lyons. The five-mile trail offers incredible views of the Indian Peaks Wilderness region in north-central Colorado. You may spot deer, foxes and coyotes, but beware of the occasional rattlesnake.

    Be it summer or winter, there are always outdoor activities happening at the Rocky Mountains National Park, an hour’s drive from Boulder. Enjoy its spectacular mountains, lakes, alpine and subalpine flora and fauna and over 300 miles of hiking trails. Winter activities include snowshoeing, country-cross skiing and sledding.

    Beer lovers will have a great time in Fort Collins, an hour and 10 minutes north. The city produces 70% of Colorado’s craft beer and is home to over 20 breweries, each with its distinctive style. Free brewery tours are offered by Odell Brewing Company, Fort Collins Brewery, New Belgium Brewing Company and Anheuser-Busch Brewery.

    Tips and tricks for driving in the US

    American cars usually have automatic transmission. Drive on the right-hand side. An international driving permit is not compulsory but recommended. Carry it at all times along with ID (passport) and proof of insurance.

    Speed limits vary from state to state; in general stick to 70mph on motorways. Beware that undertaking is not illegal in the US; to stay safe, don’t forget to signal before changing lanes.

    Provided there is no oncoming traffic, you can turn right at red traffic lights. At a four-way stop, all cars should stop, and the one that arrived first sets off first followed by the others in the order of arrival.
