This, I believe, most of outdoor people once in a while do have to deal with rashes between thighs, around the groin. This may really screw the entire trip and make it annoyingly miserable to walk any further.

The best that I thought I can do to avoid them, is I apply coconut oil before starting. But,when you trek through waterfalls or cross streams, this habit doesn't work. And, after that when I sustain such rashes, there is hardly anything that I can do.

Still, what can be done? What should be done to avoid them? And, what I can do to suffer less anyway if I sustain that thing?

I found the best answer is tight underwear made from a slippery fabric with legs that extend just far enough down to cover where things rub in the crotch area.

I currently have a pair of Underarmor brand that work very well. They are made of a stretchy but slick synthetic fabric. The garment stays in place on the skin. That means the skin doesn't get rubbed and the garment takes the abrasion instead.

The only downside I've noticed is that since these things are kind of slippery, I have to make sure I tighten the belt of the outer pants properly else they tend to fall down more than with regular cotton underwear. That only applies to long pants, like jeans. Shorts are apparently light enough so that this doesn't matter.

You might think that this kind of underwear would be hotter, but that turns out not to be the case. I guess because it's always right up against the skin it doesn't trap any air, and the fabric itself is so thin as to not have appreciable thermal resistance.

Lanthrop: Okay, Thanks for the suggestions related to selection of under-garments. I will consider them from now on. Thanks a lot! –  WedaPashi Aug 2 '13 at 5:10
@Lathrop This is the exact solution I use. Loose boxers are the enemy on a long, hard backpacking trick or serious run. –  theJollySin Aug 8 '13 at 16:32
I second this in major way. Synthetic or merino boxer briefs are the single most effective way to fight chaffing rashes from long-term hiking and running. This is not only because they provide a layer of tightly fitting fabric to take the friction, but largely because they help keep you dry. Moisture is not your friend here. It increases friction and can lead to fungal infections. –  manoftheson Mar 3 '14 at 3:28

You can prevent this by getting some talcum powder (baby powder) and putting it where you usually get the rash. Depending on how much you're sweating, apply it every few hours.

Also wear tight and long underwear so you minimize the friction, it's certainly the cheapest solution.

Give it a try, I had some "horror" hikes because of that, it just messes up the whole trip.

Talcum Powder is a staple in my backpack for this very reason! –  Affable Geek Aug 2 '13 at 14:26

You may be fighting an uphill battle, and may have a fungal infection.

That was the case for me, which made it very hard to keep from getting rashes when backpacking/camping, or really, going anywhere without being able to shower daily.

I went to the doctor and had them prescribe me an anti-fungal medicine, which was Tolnaftate, the active ingredient in tinactin, lamisil, etc, for athletes foot and jock itch.

After taking that for 10 days, it was like night and day, and I was virtually immune to it afterwards. I shortly thereafter went on a weeklong backpacking trip. Despite being relative filthy from not showering for 7 days, with only a single pair of polyester underwear, I was nonetheless free of any rashes. I did smell pretty awful though. :)

It depends what the OP means by "rash". Some people might describe chafing as a rash, but jock itch is something worse for sure! –  hippietrail Aug 19 '13 at 3:19
@hippietrail: that is true, however the OP mentioning that his efforts were ruined by going through wet areas, leaving him moist and unable to dry. That is the breeding ground for fungal infections. –  whatsisname Aug 19 '13 at 13:52

The main solution I've found to this is to wear looser clothing in the groin area. Boxers made of polyester or wool or something that breathes well. Shorts as well if at all possible, but if not, pants with mesh in them somewhere.

Beyond that, if you start getting a rash, dry out after you cross streams. Use a product like Bag Balm or similar, often comes in stick form (looks like a deoderant stick).

Drying out every now and then doesn't seem always possible. But, using a product like Bag Balm, I think is a good suggestion that I receive from you. Thanks! –  WedaPashi Aug 2 '13 at 5:09

The goal is to not to get wet or stay wet so wear the lightest most breathable clothing possible. Even so, I put Goldbond in my shoes and in my crotch every morning when I'm on the trail.

If your skin gets wet after crossing a stream or freak rainstorm you may consider stopping and drying out the skin and putting on new dry clothes. Hiking miles/km with wet skin that is being rubbed constantly WILL make for an uncomfortable trip.

Hikers bring rain gear not because we are afraid of getting wet, but because we are afraid of the chafe and hypothermia.

I made an edit in the last line of the answer. At first, when I was going through what you are saying, made me read the line twice. I may be wrong, but with all due respect to yout thoughts, I thought of reframing it. –  WedaPashi Aug 8 '13 at 12:45

You may think this is insane, but wear women's nylons. Cowboys do this while riding horses in the spring, before their skin gets calloused.
