I did the trail with my all-time favorite hiking partner, my daughter. We started at the Mesquite entrance, though unfortunately we had to park the car about three blocks downhill from the trail head. There were several no parking notices beyond where we were able to park; thus we had what I call a 'hike to the hike'. A very good aerobic hike, all mostly uphill. We made it to the picnic tables. Pluses were that we can look into the canyon to see the massive flowing Tahquitz waterfall, and you can see the sprawling city view of all of Palm Springs and parts of Palm Desert, along with the thousands of palm trees inside. Negatives include limited wildlife, with just the basic sightings of several lizards. Other than a few heathy looking barrel cactus, the variety of the cactus and desert shrubbery was limited. Lastly, though we are fortunately in wildflower season, this particular trail did not have the spectacular array of blooming flowers that the other trails exhibited. Friendly hikers were found periodically during our hike, though none were seen traversing farther than the picnic table areas. Special shoutout to the entirely barefoot Italian woman we met who taught us perfect hiking etiquette when passing parties on narrow trails.
The South Lykken Trail has two trailheads, both of which have parking. Bike tethers don't exist at the north trailhead (a block west of Belardo and Mesquite), and some cyclists might consider the fencing near the south trailhead to be adequate (on South Palm Canyon Blvd, south of Murray Canyon Blvd).
The 4 entries for South Lykken all refer to the same trail, and treat its two trailheads as distinct. However, the full trail is about 6 miles from one trailhead to the other. Two sets of picnic tables are just past the climbs that initiate the trail from each end.
