Do not throw rocks, dislodge a rock, start a rockfall, start a fire, or impact the ecosystem in any whatsoever.
Respect the sounds of nature. Don’t play music or make loud noises on the trail, as it scares birds and animals. People also have different interests in music and may not agree with your choice of music on the trail. Importantly, many trail users visit trails to escape the noise of the city and connect with nature. If you want to listen to music, use earphones/headphones but at a level that you are still aware of what’s happening in your surroundings and with other trail users.
