Hey active explorers tired of the coastal heat, if you're around Santa Marta this mid-December, escaping up to the Sierra Nevada de Santa Marta's highland retreats feels like the perfect move right now, with cooler temps kicking in as you climb elevation, trails drying out nicely in the start of the dry season, and spots for treks to indigenous villages plus natural hot springs drawing folks looking for that mix of adventure and chill amid lush greens that still pop even without full autumn colors down here in the tropics. Yeah its prime timing with December marking the drier window from here through March, less chance of heavy rains soaking your hikes, and the mountains offering a real break from the Caribbean warmth below, temps dropping to comfy levels for effort without overheating.

What's pulling travelers up there lately?
