This is a really beautiful location. Only about 20 minutes from Quartzsite.
There is another location nearby named Kofa National Wildlife Refuge - Palm Canyon Road, however this location differs as it is BLM land whereas the other location is a national park. Camping in an RV or trailer is better here as there are much bigger sites. many already have fire pits built from rocks. The road is unpaved but was recently grades and fairly smooth.
I have T-Moble service here and have good phone service, LTE data, but extremely slow. Better than nothing.
This road is 20 miles from Quartzsite, so it isn't tightly packed. Lots of fire pits, easy drive in. If you're staying for the season, you can alternate here and Plomosa Rd. At a certain point this road turns from BLM into Kofa Wildlife Refuge, so be mindful of where you camp
Free dispersed camping, about 23 miles south of Quartzsite, with no services available, but lots of space and stunning views of surrounding mountains. Camped here for 3 days and loved it! Many RVers were using solar panels instead of generators, adding to the serenity here. In addition to RV access, there are a couple of beautiful tenting areas near the entrance to Palm Canyon. No water or toilets nearby, so plan ahead!
Awesome hiking and mountain biking in the area. Be sure to visit Palm Canyon and Kofa Queen Canyon -- very different from each other, but both are spectacular. Kofa Queen is accessible via OHV and mountain bike as well as on foot. Palm Canyon is a fun, scrambling hike and much more difficult than Kofa Queen, but absolutely worth it.
Sunrises and sunsets are endless and beautiful! Easy access back into town (via Hwy 95) for food, gas, firewood, laundry, and just about everything a camper could need.
