As I bounced around in the front seat of a Land Rover, Bette Davis' famous line in the movie "All About Eve" flashed through my mind: "Fasten your seatbelts — it's going to be a bumpy ride."
It's impossible to overstate the bumpiness of this ride. Six of us, plus our driver, Sherman, were traversing the rugged terrain in Arikok National Park, an area of caves, sand dunes and limestone cliffs on Aruba's eastern side.
Covering almost 20 percent of the island, it's an arid, harsh environment, more reminiscent of the deserts of Arizona and New Mexico than the lush tropics of the Caribbean.
Here, vegetation tends to be cactus plants rather than Aruba's signature divi-divi trees, while the dry desert conditions make it hospitable for wildlife such as rattlesnakes, iguanas and the beautiful cododo, an iridescent turquoise lizard.
The park attracts visitors who come not just to marvel at the lunar-like landscape, but for attractions natural (the serene Natural Pool, sandwiched in between the cliffs) and manmade (the remains of a once-flourishing gold mine, cave paintings done by Arawak Indians and the surprising Alta Vista Chapel, a sunburst of bright yellow).
A journey to Arikok is a highlight of any visit to Aruba, and the Land Rover adventure, offered by De Palm Tours, will delight adrenaline junkies. Those with bad backs as well as pregnant women would be wise to opt for a hike led by one of the park's knowledgeable rangers.
The Land Rover excursion had been arranged by my accommodation, the Aruba Marriott Resort and Stellaris Casino, located on the dazzling white sands of Palm Beach.
This is the Aruba of travel posters and vacationers' dreams. Lush landscaping links the resort's various buildings to a series of cascading waterfalls and pools (one for families and one for adults only), shopping arcades, a Mandara spa and six restaurants.
