NOLS and SOLO are the gold standards. I let my cert expire since I'm no longer leading works hikes into the woods. I've always been certified through NOLS.
Landmark Learning is a top-notch, NOLS affiliate. I really enjoyed and got a lot out of each cert course. The "real-world" scenarios they provide give hands-on experience triaging and treating patients. There's a blend of classroom and outdoor exercises. We almost had a real exercise when a pygmy rattler decided to play in our area.
What's your goal? I've seen that ARC supposedly provides WFA but I can't help but wonder what their expertise is in the field. Wilderness first aid differs (imho) greatly from your typical FA instruction since it's geared towards tracking vitals, performing extractions, long-term patient management, etc. as opposed to maintaining the patient for a few minutes until advanced support can arrive.
Unfortunately, Florida isn't on most of the trainers radar. I think Landmark only makes one or two appearances/year. I'm not aware, however, of any that are done that far south. The only places I've seen it offered is Gainesville (Florida Outdoor Academy/SOLO) and Tallahassee (Landmark/NOLS). It looks like there's actually a Jan
SOLO course at the Gainesville Bass Pro. FL Heartsavers does courses at Paynes Prairie. And NOLS has a course near Orlando in Aug 2019. I didn't see anything further south than that. Tampa/Orlando seems to be the line of demarcation.
Let me know if you have any specific questions.
