best time to visit
Costa Rica
Costa Rica creator coverage of optimal timing is thin in this set — most videos focus on specific regions or activities without anchoring to seasons. Emma Terra's mistake-avoidance guide implicitly signals that planning and pacing matter more than a single ideal season, warning against cramming too many destinations into a short trip. The 1-week itinerary content from Emma Terra suggests year-round viability across regions like Arenal, Monteverde, and the Pacific coast. Creator coverage does not surface a clear dry-season vs. green-season breakdown in this corpus.

Peru
Peru creator coverage of timing is also limited, but Stef's Peru Travel Tips raises altitude sickness as a critical planning variable tied to high-altitude destinations like Cusco and Rainbow Mountain — implying that physical preparation, not just calendar timing, drives when Peru is best visited. The Inca Trail difficulty guide from Inkayni Peru Tours highlights that the classic 4-day trek tops out at 4,215 m at Dead Woman's Pass, reinforcing that fitness and acclimatization windows shape the optimal visit window. Neither corpus provides explicit month-by-month guidance.
