20M first solo trip to Colombia (June, ~3 weeks) — Medellín vs Cartagena vs other spots? + tips for meeting people

What’s up everyone,

I’m 20M and this is going to be my first time solo traveling. I’m planning a trip to Colombia around mid-June for about 2–3 weeks.

I’m mainly looking at Medellín, Cartagena, and maybe some other spots, but I’m open to anything.

I had a few questions:

- Anyone else going around June?

- What are the best cities/places I should NOT miss?

- Any underrated spots or experiences?

- Good places to meet people / nightlife / social vibes?

- Is it easy to meet other solo travelers out there?

I plan on hitting the gym, exploring, and just enjoying the experience, so any recommendations are appreciated.

Also if anyone is gonna be out there around that time, I’d be down to connect 🤝

Appreciate any advice!
