I’d say Red Rock Canyon is the best hiking and scrambling destination in the world this close to a major city. Las Vegas.
Over the years I’ve done all of the established hikes.
BUT more recently I drive or cycle to nearby Calico Basin. Free entry. Free parking.
THEN take the Calico Hills Overlook Scramble to Red Rock Canyon. It’s obvious and easy from the parking lot.
Once in the red rock, I wander and scramble wherever I like.
