- Clothing that you don’t mind getting wet. You won’t need a wetsuit, but pants/shorts and shirts made of quick-drying synthetic fabrics are ideal for kayaking.  - Warmer clothing, including long-sleeved shirts, pants, and even a jacket. The air and water in the caves are both colder than average, so it’s likely you will get cold while you’re inside the caves. However, make sure you can easily remove these additional layers because the air/water outside the caves will be hot/warm.
