My mom won't approve my international travel

Next month, I'll be visiting my friend which has been involved with marriage tours for years in Colombia. But there's a problem, my mom won't approve my international travel. She said it's too risky for me, for my age. But dude, I'm already 26! Is there any problem with that? I already have my itinerary for my 5 days visit in the country and I can't just cut this off! I know my mom is just trying to be protective but I'm pretty sure I'll be safe in my travel there. What should I tell to my mom? I need your advices guys!
