Route Description for The Tunnel
The Tunnel Trail is a rugged route to a unique geological formation just off of Main Park Road in Arches National Park. This hike does not have a well-defined trail, so bringing along a map and/or GPS unit is highly recommended. The last little section of trail up to The Tunnel is steep; solid footwear with good grip is necessary for this section. The Tunnel itself is a 4-foot-wide, 5-foot-tall, 53-foot-long tunnel through a sandstone buttress that was formed by gradual water erosion. If you stick your head in the tunnel, you will see the trickles and drips that continue to chip away at the walls of The Tunnel to this day.
From the parking lot, follow the path to the left, heading towards courthouse wash. Hug the large rock formation on your right as the trail swoops up to track northwest. Continue northwest for 1.0 km past two more large rocky features on the right. After 1.0 km, turn to your right and head northeast for 0.6 km to the Tunnel.
Check out this fascinating feature and have a rest in the shade before turning around and following your footsteps back to the parking lot.
