Last Known Status | Open |
This area has many miles of designated off-road trails with sand washes that wind past old windmills and corrals in the rolling desert hills.
There are plenty of easy to moderate trails, as well as some advanced level single track routes, with some trails stretching all the way into neighboring regions. While most of the land is BLM, there are some adjoining areas that may require a State Trust permit to ride.
The main staging area is large, flat, and meticulously maintained. There is a separate beginners area that is sometimes used for ATV training courses. The staging area can be busy on weekends, but due to the large number of good camping spots you can usually still find a comfortable place.
Much of the vegetation surrounding the staging area is protected so do your best not to trample it and always save your riding for the trail. The Boy Scouts and local riding clubs often do the trail and staging area clean up, so this will continue to be one of the best riding choices near Phoenix, as long as people take care of it.

Comment | Arizona State Parks OHV Sticker Info |
This is a large area with all types of terrain, including some single track. The scenery and surrounding cacti vegetation is spectacular, especially during the spring months.
All of the motorized trails are marked to show what off-road vehicles are permitted. This trail is open to dirt bikes, ATVs and Jeeps.
A good portion of the ATV trails are wide and hard packed with some loose gravel. This is a good place to bring beginners, families or a group ride.
There is a flat novice / pee-wee learning area at the staging area which is fenced off for safety. This area is limited to small riders and ATVs 40 inches or less in width.
With mild fall and winter temperatures and hundreds of miles of motorized trails, Boulders OHV is a good choice to plan your next off-road vacation.
There are some designated single track trails just for dirt bikes. These trails are rocky and hard packed, which is typical of Arizona terrain.
Another view of the type of terrain you will encounter at Boulders OHV Area.
Some of the sand washes have a few rocky sections but they can easily be avoided.
This section of single track motorcycle trail is rugged and steep but still a lot of fun.
Coming down on this single track motorcycle trail is a lot easier than going up.
The saguaro cactus is plentiful here. This is also the Arizona state flower.
Due to the width and light moderation changes, these trails are mostly geared for ATVs and UTVs but are still worth exploring on a dirt bike.
The single track is rough and rugged with steep climbs. Get a good run and choose your lines wisely.
The ATV trails have some light to moderate elevation changes but nothing to scary.
Another view of the trail markers. Most trails are open to all off-road vehicle types but some are only open to ATVs and dirt bikes.
You will encounter the occasional section of loose chunk rock but most of the motorized trails are hard packed with loose gravel.
This trail system is unique thanks to the beautiful Sonoran desert landscape.
