Narrow it certainly is, because at some points along this trial, the 2000 ft-high canyon walls that flank each side are only a few metres apart. That means wading along the bed of the Virgin River enclosed in a world of towering cliffs, hanging gardens, waterfalls and sandstone arches. It's an unforgettable experience.
In this case, the name doesn't really do the place justice. The hike to Observation Point takes in beautiful Echo Canyon, but it's the stunning panoramic view at the end of the trail that's the main attraction: an eye-popping vista across all of the canyon's major landmarks, making for a truly spectacular sight.
Kids love getting a cooling face mist from a curtain of water that permeates the cliff-face at Weeping Rock and falls like a curtain across an alcove clustered with hanging gardens. The easy walk to get there provides plenty of photo opportunities too, with stunning views of the Great White Throne.
If you have even a touch of vertigo, this isn't the hike for you. Along the steep ascent you'll pass stunning scenery, plus you'll be rewarded with a dizzying view of the canyon from the top. But be warned that the last part of the trail is along a knife-edge ridge and has the kind of steep drop-offs to make your stomach flip.
When you visit Zion National Park, be sure not to miss its quieter north-westernmost reaches, where the red cliffs and narrow canyons of the Kolob Canyons stretch out across the landscape. Take time to seek out stunning Kolob Arch - at 287-ft wide the second longest free-standing arch in the world.
