Our scheduled activities include a variety of ranger-led programs, from easy walks and evening talks, to all-day hikes, boat tours and Native America Speaks programs. A day of hiking can expose you to more sun and UV rays than normal. Wear a hat and sunscreen. It will help keep you cool and prevent a sunburned scalp! Bring water with you! The mountains can get very hot in the summer. Surface water in the park may be unsafe to drink. Children are welcome on interpretive activities, but should always be accompanied by an adult.
