Make sure you understand the rules and regulations of the individual pueblo or reservation. Do not bring alcohol, weapons, drugs, or pets with you. Do not enter a building unless you are sure it's a public building. It's extremely rude to enter someone's house without an invitation. Kivas, graveyards, and other sacred places may not be entered.
Dances are spiritual in nature.
Please act as though you were in your own place of worship. Do not applaud or otherwise treat them as entertainment. Do not hike or camp on reservation land without permission. Keep your children with you and make sure they are respectful. Do not climb or sit on structures.
