There are hundreds of miles of unpaved roads in Canyonlands, providing access to various campsites, trailheads, and viewpoints in the park's backcountry. Most roads require high-clearance, low range four-wheel-drive. These roads range in difficulty from intermediate to extremely technical.
If you have two days to spare, take one day to explore Island in the Sky and the other for the Needles District. Much of Canyonlands is only suitable for 4x4 vehicles. These four-wheel-drive roads start at an intermediate difficulty and range to extremely technical.
The Needles, though not as easy to access, also offers an incredible scenic drive that can be done in a day. Continuing 6.5 miles drive past the visitor center and ending at Big Spring Canyon Overlook, this stunning driver has several pullouts to short hiking trails, viewpoints and picnic areas.
Hiking shoes:If you'll be visiting in the wintertime, some of Canyonlands' hikes, especially on rocky surfaces, can get quite icy, so I'd recommend bringing proper hiking boots (I've used these Merrell's for years and men's equivalent can be found here).
Ideally, you need at least two days in Canyonlands National Park. With two days, you can visit both Island in the Sky and The Needles. Each additional day you add gives you more time for some epic adventures, such as the White Rim Road, white water rafting, backpacking in The Needles, or exploring The Maze.
It would take days, weeks even, to fully explore all that Canyonlands has to offer. However, if you only have one day in Canyonlands, you have just enough time to visit the highlights. There are several different areas of Canyonlands National Park.
The only fully-paved road in Arches is Scenic Drive, a 25-mile, out-and-back road that passes the majority of the park's viewpoints and trailheads. If you're tight on time or don't enjoy hiking, you could drive the park—stopping 10 minutes at each viewpoint—in about three hours.
Both are great if you're really short on time but Arches is the clear winner on this one. Canyonlands is great to see in just a few hours but it's almost an hour from Moab, too, so taking that into account, Arches is better with limited time.
Half a Day: In addition to enjoying the scenic drive, hikers can explore the Slickrock Trail or walk to the edge of Chesler Park for a closer look at The Needles. Visitors with four-wheel-drive vehicles might consider driving to the Colorado River Overlook. Spend some time at the visitor center learning about the area.
There are 3 different park entrances for Canyonlands National Park. These entrances must be accessed separately, as they do not connect inside the park. Let's explore the routes for visiting from the gateway city of Moab. For those coming from the north of Moab, US 191 to UT 313 will bring you to Island in the Sky.
If you only want to see a few highlights in each park, then yes, one day in Arches and Canyonlands is enough time. For a better experience, add one more day to your itinerary, so you can spend one full day in Arches and one full day in Canyonlands.
The best times to see most wildlife are early and late in the day, especially in the summer, when the midday sun drives all Canyonlands residents to search for shade.
Canyonlands in Moab, Utah, has some great views and some very pretty overlooks, but unless you are spending some time driving the off-road trails or camping on the White Rim Road, the typical person would probably spend half as much time in Canyonlands than in Arches.
For those who aren't up for the hike, there are two other viewing options: The Lower Delicate Arch Viewpoint just down the road only requires a 100-yard walk over flat ground to get a fine look at the arch from a mile away.
