This is the place to watch the sunset. Accessible only by the free shuttle bus, you have to park by the village and board the shuttle for a 15-minute ride to Hopi Point. Because it's a popular place to watch the sunset, it gets crowded. The line for the shuttle can get a little long, so arrive early. If you get to the shuttle stop at least an hour before sunset - and 90 minutes early is better - the line shouldn't be too bad. For an extra enjoyable way to watch the sunset, hit the grocery store in the village and pack a picnic dinner. It will allow you to have a relaxing dinner as you watch the sunset over the canyon, and you won't have to rush back to eat after the sun goes down.
When you get to Hopi Point, stake out a nice spot facing west. Again, it gets crowded, so you're better off arriving early if you want to find a spot to sit and enjoy the views without a crowd of people in front of you. The line to board the shuttles back gets long, so either hurry to the boarding area as soon as the sun sets or wait 15 minutes before heading there, to give the line time to clear out.
