Phoenix travel tips
1) Where should I go hiking in Phoenix if I'm a beginner? | If you go hiking first, prefer Camelback Park near Phoenix. There are two trailheads: Echo Canyon is a steep and rocky climb for more experienced hikers. And Cholla is a steep but not as rocky trail, which is perfect for beginners. Moreover, this place is always crowded in case you need help |

2) Where can I drink wine in Phoenix? | Spend an amazing evening at the Postino Winecafé at 3939 E Campbell Avenue in Phoenix. Relax at the cozy patio and order some bruschetta (try the burrata with bacon, arugula and tomato). They have a wide range of great wines by the glass for $5 from 11:00 to 17:00. |
3) Get into the Hole-in-the-Rock in Phoenix, a real natural wonder | Walking around Papago Park in Phoenix will lead you to the natural wonder, Hole-in-the-Rock. It is a low sandstone hill perforated with openings created by the flow of water over millions of years.The light at sunset and the views to downtown are worth climbing! |
