How to Pack for Rainforest Hiking in Costa Rica

Pack moisture-wicking synthetic fabrics, broken-in waterproof hiking shoes, and a lightweight rain shell to manage the high humidity and frequent downpours. Focus on gear that dries quickly overnight, as traditional cotton clothing will remain damp for days in the jungle.

  1. Select your base layers. Avoid cotton entirely. Bring three sets of synthetic or merino wool t-shirts and shorts. These fabrics pull sweat away from your skin and dry within hours if you get caught in a rain shower.
  2. Choose your footwear. Bring trail runners or hiking boots with aggressive tread; the trails are often muddy and slippery. Ensure they are well broken-in before your trip to prevent blisters. Pack two pairs of wool hiking socks per day to ensure you always have a dry pair.
  3. Protect your electronics. The rainforest environment is brutal on tech. Use a dedicated dry bag for your phone, camera, and power bank. A standard water-resistant backpack cover is not enough during a heavy tropical storm.
  4. Manage your insect defense. Pack high-percentage DEET or Picaridin repellent. Keep a small travel-sized bottle in your daypack at all times, as re-application is necessary every 3-4 hours due to heavy sweating.
Should I bring hiking boots or trail runners?
Trail runners are generally better because they drain and dry faster than heavy leather boots, which can stay waterlogged for days in the rainforest.
How do I keep my clothes dry?
Pack your clothing inside compression dry bags within your main backpack. This acts as a secondary layer of protection against humidity and unexpected river crossings.
