May/June or September/early October is the best time to hike 52 Tunnels which will give you milder weather and fewer crowds. If you hike in Summer, go early to avoid the heat and crowds as much as possible. You can check the status of the hike and webcam online to help plan your visit.

52 Tunnels has one of the coolest trailheads I’ve ever seen with a large sign and photos lining the walking trail before the start of the hike. It creates a unique atmosphere to start the hike and is a nice tribute to the history of the tunnels which were created in World War I by Italian soldiers.
