Two of the lesser known and least visited canyons in Anza Borrego Desert State Park are Cool Canyon and Rainbow Canyon. This last weekend I visited both. These canyons are semi slot canyons and reminded me a lot of canyons in Death Valley in that they narrow up and have lots of marbled, swirled types of rock. You can use Cool Canyon as a starting point to climb Granite Mountain, I made a last minute decision to try and get to the top but I stopped at Peak 4624, I just wasn't prepared to go another 1,000' that day.
Rainbow Canyon is another great little canyon that is only a mile or so long and great for a quick hike or family exploration opportunity. If you are camping in Blair Valley and have someone who can drop you off at the canyon mouth you can hike in and over to Blair Valley for about a 5 mile easy going but fun hike.
You can see all of the pictures from Cool Cool Canyon here and Rainbow Canyon here

Morteros nearby indicate past Indian occupation in the area
Some quality scat entering the canyon
This appears to be a Hawk Massacre
One of many dry falls in the canyon
Another larger dry fall
Some Honeycomb up in the rocks, this was a great find
My lunch on Peak 4624, you can see Whale Peak straight ahead in the distance
Looking back at Peak 4624 as I descended
After Cool Canyon I headed over to Rainbow Canyon for a quick couple of hours
Here is the entrance to Rainbow Canyon
You will almost immediately see the first dry fall, there are many and they are all fun to climb and easy to get over unless you decide to wear Stilettos on your desert hike...
Lots of marbled rock in this canyon

Here is a narrow section of the canyon
This is looking down probably the largest dry fall, it is actually a "double" dry fall

Both of the canyons are great for a quick 2 mile hike and are family and kid friendly
