Camping and climbing in Joshua Tree in Feb - Need Advice!

I’m looking to go to Joshua Tree in mid February to camp and climb. Few questions.

1) Any recommendations on campgrounds in the park? I’m looking at either Black Rock or Cottonwood for the potable water. I’d like to make a reservation so I don’t have to worry about finding a campsite when I arrive.

2) Any recommendations for places to rent camping gear? Thinking that may be easier than cramming it into a checked luggage. I’m planning on flying into Palm Springs airport.

3) Any recommendations for guide services? Or does anyone want to climb? I mostly climb outside at the Gunks and I’m a new trad leader. I’ve climbed at Joshua Tree once before. I’ve climbed a 10a slab (Remembering Marina). Much lower grades for cracks probably. 

4) Any recommendations for things to do during the off days, besides for hiking?

1. Camping: I recommend Ryan or Sheep Pass for reservations and proximity to climbing. You can fill up water jugs at the entrance station. Black Rock will require you to wait in traffic to get into the park, and Cottonwood will add a lot of miles of driving. 
2. Renting gear: Not available as far as I know. REI rents stuff, but you'd have to detour to Rancho Cucamonga or instead fly into Ontario. Palm Springs Airport is small and doesn't suck to wait at for checked bags. Your carry-on may get checked anyway because the planes that go there are small.
3. Partners/guides: Climber Coffee is a good place to meet people. There are dozens of guide services (I work for two of them); my best advice is to ask your network about individual guides they recommend, because personality/compatibility can take your experience from good to great. Based on your location, you might know folks involved in Rise Outside Collective or Flash Foxy, and they have friends who operate here. 
4. Rest days: Wonder Valley Hot Springs, thrift shops and crystal shops in Yucca Valley, various art exhibits in the middle of the desert, endless scrambling, the new Visitor/Cultural Center in 29 Palms. 

#1:  Both those campground are a long ways from the climbing.  Try Hidden Valley, Ryan, Jumbo, or Indian Cove.

#2: Maybe call the local gear shop (Nomad Ventures, (760) 366-4684) for ideas.  There used to be a place that did rentals.  It might have folded.

#3:  Vertical Adventures or Cliffhanger Guides.  Or just find a partner when you get settled in camp.  That should not be a problem.

#4:  I hear that a local head shop in Yucca Valley is now selling psilocybin for "research" purposes.  Datura is always free in the park.  Enjoy.

Hurry and get your reservations. Most week-ends in February are already booked, precluding a nice continuous stay of more than 5 days.

Hello, following this. But also planning to be in JTree around Feb. If you want to climb, Tiffany, shoot me a message whenever. I'll follow trad and down to get on whatever else sport/boulders are out there.
