Where should i explore

im looking to take a trip to celebrate being done university and college this year. After 2 years of college and 3 years of university i need to get away and take a break while im still young. Im from Toronto (Canada) and looking to take a month long trip. I’m looking for an adventure rather than a vacation. I don’t want to sit around on a beach, i want to climb mountains and explore.

Any suggestions where i should go? i was thinking south asia (thailand/vietnam) or mayb even europe
