Watch out for little red frogs on the trail. You will be wading through knee-deep water in a couple of places. So wear a pair of sandals for this short hike. The rocks near the streams and the waterfalls are quite slippery.

You will need your bathing suit and a towel. The hotels usually loan you a towel if you don't have one. The vehicle is usually parked along the road, but I would not leave any valuables in the vehicle. If you buy any souvenir at the Bri Bri or Kekoldi Indian reservation, you will want to take them with you to the waterfalls. Stay away from buying the animal products such as claws.

I have seen a snake and some poison frogs in the little forested area between the beach and the road. Most hotels are located west of the beach road, but it is really no big deal to walk extra 50 yards and cross the road. Army ants are all over the place and so are the leaf-cutter ants.

These army ants are quite aggressive. They raise their torso to strike back if you try to scare them with sticks or leaves.
