Oasis

The Oasis of Mara is technically outside the border of Joshua Tree National Park, behind the visitor center in Twentynine Palms, but it's still considered part of the park.

It's not as impressive as being in the park, mostly because houses and buildings are visible only a few hundred yards away. But the path around the oasis is paved and very easily walked in a short time. It's certainly worth stopping for at least a few minutes.
