What essential gear should I bring for Costa Rican trekking?

Bring lightweight, moisture-wicking clothing, a durable pair of trekking boots (like Salomon X Ultra 3 GTX), a reliable hydration system, trekking poles for stability, and a waterproof jacket to combat sudden rains. Don’t forget a first-aid kit and insect repellent for added safety.
