I’ve been wanting to get here for YEARS.
Best hiking destination in the Park, no doubt in my mind, is Lost Palms Oasis. That’s 7.5mi (12km) return from the trailhead to the Palms.

The walk is scenic, varied desert environs, until suddenly a huge palm oasis appears far below trail level:
In early March, most everyone in the park was shooting Spring wildflowers. Including me.

There must be a thousand climbing routes in JT also.
Desert hiking has its very own ambiance…
