Peru/Colombia itinerary to maximise wildlife

Hey all — keen for a sense check on our Colombia itinerary after Peru.

We prefer hiking, wildlife, birding, trail running, snorkeling/diving etc over cities/nightlife.

Current rough plan:

• Finish Huayhuash + Santa Cruz near Huaraz
• 4 nights in Iquitos Amazon
• Fly to San Andres + Providencia
• 7 nights Providencia
• Fly Providencia -> San Andres -> Santa Marta
• 5 nights Minca (birdwatching, hiking, coffee, swimming etc)
• 3 nights Tayrona
• 2 nights Cartagena before flying home

Questions:

• Is 7 nights in Providencia too long or worth it given the effort to get there?
• Would you cut Tayrona entirely after already doing Providencia + Minca?
• Are the Providencia flights as unreliable as people say in June?
• Is Minca genuinely worth 5 nights if we enjoy nature/birding/slow travel?
• Are we underestimating how exhausting the humidity/transit will feel after Peru?
• Anything obvious we are missing?

We considered Medellin but honestly we tend to enjoy nature-heavy places more than cities.

Would especially love input from people who have done both Providencia and the Santa Marta coast.

Thanks!
