Have you tried using meet up or any of the Facebook groups such as what's going on Riverside County or what's going on Corona?
If you want to meet on Foothill Drive at the base of Skyline Drive Trail at 5:45 Tuesday night. We hike every week throughout the year. Usually 5 to 10 people hike and we are gone for 2 hours up the mountain side along a fire Trail and then back.
Have seen certain groups, unfortunately can't tell how they organize ...
If you live close to skyline, there is one group that go every Tuesday or Thursday. ..you have to be corona neighbor to join the group.
None it's mostly homemade groups
