I've never tried couchsurfing before and have heard wonderful experiences from my friends who have tried it, so here I am! I love to travel(who doesn't, right?) and i guess the best way is to meet the locals, learn from them about that particular place and activities rather than just rely on the internet for the "top destinations that you must go before you die". Unfortunately, I am unable to host, but I am more than willing to bring you around!

Not really amazing but the first thing that came to my mind was the bungee jump that I did in Phuket and second one would probably be getting 'lost' while trekking up a mountain in Japan when it was snowing.
