The Hohokam Tribe utilized this landmark to measure summer and winter solstice in early Phoenix. Early people could schedule their growing season using the rock's sun-hitting locations.
A smaller route goes to flat desert where you can photograph sagura cacti on the other side of the Hole in the Rock. If you've been in Arizona's heat, it'll lead you to shade.
Hole in the Rock in Papago Park is a short, easy hike with a great perspective over Phoenix for families. Just plan and time it to avoid crowds and heat.
