In winter, wear warm clothes and waterproof clothing. In summer, do not hike during the hottest parts of the day (10AM-4PM). Wear lightweight, light-colored, loose-fitting clothing. Wear sunscreen, a hat, and sunglasses. Always wear proper footwear due to rocky, uneven terrain and slick and sometimes slippery rocks. In all seasons, carry plenty of water and salty snacks (ex. pretzels, crackers, chips). Stay hydrated with plain water and an electrolyte drink replacement. Stay cool in summer and warm in winter and take rest breaks. Know your limits and turn back if needed. Let someone know your plan before you go.
Plan ahead and prepare. Take only pictures and leave only footprints, leaving objects as you find them. Observe wildlife from a distance and avoid loud voices or noises to be considerate of others.
