Peekaboo Loop Trail picks up right at the bottom of the the Navajo Loop trail. This hike is a no brainer addition if you plan on doing Navajo Loop. Peek-A-Boo takes you a bit deeper into Bryce’s amphitheater, packed with crazy looking hoodoos and a ton of natural arches. The variety and density of interesting stuff along this trail is pretty impressive. What should have taken us 2 hours to complete ended up taking 3 as we continually stopped or veered off the path to check out some epic viewpoint or natural arch. This hike is a bit more unknown so if you didn't have to start off on the Navajo Loop, we might say you can stroll through at any time.
While you don't have to fight off the crowds quite as much on this trail, we still recommend going earlier in the day or later in the afternoon. The hoodoos really catch the light much better in the morning or afternoon light and also cast way more dramatic shadows. Naturally, this is pretty much the case everywhere, but the difference is even more noticeable at Bryce Canyon.
Bryce Canyon is a bit higher elevation than it's neighbor Zion, so its usually around 10 degrees cooler and tends to get a bit more snow. If you are considering visiting anytime between December and March, you'd be rolling the dice. This trail does get shut down when there is too much snow and ice. Last time we visited, it was in late November and even then, there were some pretty wild stretches of ice that were pretty tough to navigate so we probably just made it before that winter's closure.
Bryce Canyon National Park is a pretty small national park and can pretty easily be knocked out in just a weekend. While there is a surprising amount of variety to a sea of hoodoos, there are really just a few headliners. If you have extra time on your hands, we strongly recommend driving just an hour and a half south west to Zion National Park. Both parks are on the smaller side compared to other national parks, so if you have a week, split it between the two and you can knock out all the best spots at both.
If you're doing the Navajo Loop Trail, then adding on the Peek-A-Boo Loop is a no brainer. 80% of the Navajo Loop traffic just turns around at the bottom and heads back up the canyon, so you get equally impressive views and natural arches with much more seclusion. This trail is a bit longer, but most of the elevation gain/loss happens on the Navajo Loop section of the trail. Be sure to go in the morning or afternoon to catch the best lighting.
