My husband and I will have 10 days to divide between Zion, Bryce, and anything else "close by". Does anyone have a thought as to how they'd divide that up? Or even where to fly into to start this summer vacation? Thanks.

My family and I are traveling to Zion and Bryce. We are also going to the North Rim of the Grand Canyon and Lake Powell. This is a 10 day trip. We live in Phoenix so are driving up, I would recommend flying into Las Vegas. Here is what our 10 day schedule looks like.

Day 1: page, AZ,
Day 2 -3: Bryce Canyon
Days 4-6: Zion
7-10: North Rim

Hope this helps.

I would never suggest rushing thru a site. However, a lot depends upon your syle.

I'm non-stop and spend very little time sitting around the front of the room sipping or in the hot tub.

Page is less than a half day from Bryce and Bryce is less than 2 hours from Zion so you'll have about a day and a half in Bryce (fine), about 2 1/2 days is Zion (it depends how much you want to see) and 2 1/2 days at the North Rim (too much?).

Here are a few places to go that are in the area---Cedar Breaks, Calf Creek Falls, Drive HWY 12 and spend a day in Capitol Reef and a day in Goblin Valley/Little Wildhorse Canyon, Calf Creek Falls, Lake Powell(rainbow bridge, antelope canyon), look into hiking The Wave(requires permit), go canyoneering in Zion, North Rim of GC.
I would spend 3 days in Zion, 2 in Bryce and divide the rest to some of the places I mention above. If you are a serious hiker you could spend a lot of time at many many places in Utah hiking. The places I mention above require 1 day each. Lake Powell would require 2 days. I would stay "in park", but you should have made reservations several months back. So, you need to make your reservations ASAP. You can find lodging in Springdale(zion) and Ruby's(bryce)as a second option.

A lot depends on your style (as others have noted) and when you plan to go. You said "summer," but exactly when? Some places will be very hot mid-summer, e.g., Zion's average high in July is 100, with a record of 115. Even at the Grand Canyon's North Rim, heat will be a major problem if you plan a lengthy hike into the canyon itself.

I agree with the others that Zion deserves a lot of time. Three nights is a good amount, although you could spend more time if you like lots of physical activity, and weather allows. I also agree that about a day and a half (2 nights) at Bryce is a good amount; you'll have time to drive to many of the overlooks, and then spend a day hiking.

If you've never been to the Grand Canyon, it's well worth seeing. The South Rim is usually a better introduction, but the North Rim will be much more convenient to Zion and Bryce, and it's a lot less touristy than the South Rim. The North Rim is also slightly cooler than the South Rim. Like Bryce, a day and a half is about the right amount of time here. That will allow you to drive to several of the best overlooks, and spend a day hiking.

That leaves three more days. Where to go? Even more than above, this depends on what you like to do. If you like to spend a lot of time hiking (and depending on the month), I'd head toward Page. Before you even get there, there's The Wave. As spirobulldog mentioned, a permit is required; it may already be too late to get one. If so, try to snag a permit for the nearby Coyote Buttes South; you may also want to hire a guide (permit still required). There's also Buckskin Gulch, arguably the longest slot canyon in the world, and a good candidate for a day hike (just part of the way through).

You can use Page as your base of operations for The Wave/Coyote Buttes South/Buckskin Gulch. In the more immediate vicinity, there's Glen Canyon National Recreation Area, as well as the previously mentioned Antelope Canyon.

Las Vegas is frequently the most convenient airport, and often has the best car rental deals as well. You could also check Salt Lake City and Phoenix, depending upon your starting point.
