Life is too short to be left with regrets, and such adventures are easier done when younger for many reasons.

That being said, please manage your expectations, what was a wonderful profound experience for me may end up being a very different one for you. The best is to go there 1) physically prepared for long hikes with some backpack (not heavy but not just daily pack neither); 2) have your mind open to handle everything that comes your way as part of adventure, both good and bad.

Plus careful with hygiene, mostly using hands sanitizer before touching any food, eating just freshly cooked meals. Some folks I know ended up with subpar experience due to catching nasty stomach infection which made it too hard to enjoy it. Using consistently hand sanitizer before any meal may be common stuff now but in 2008 I raised some eyebrows. But 3 months of backpacking in India and this and no stomach issue with such approach, that's pretty rare.
