OverviewThe map just says Swallow Rocks, at a location northeast of Grandview Peak. Yes, there are some rocks but nothing too impressive. Nearby are 2 highpoints that have over 300 feet of prominence. These are the Swallow Rocks Peaks. Both are great viewpoints and a long ridge traverses to reach these peaks keep things interesting as well.
Getting ThereThe easiest route would be if you had permission to use the roads coming out of private land of the East Canyon Resort. I heard several ATVs using these roads.
Big Mountain Pass, Great Western Trail AccessFrom I-80 in Parleys Canyon, take the East Canyon Exit 134 (Highway 65) north 8 miles to Big Mountain Pass. Park in the large dirt lot at this historic pass.
Lookout Mountain Access
One could also get to these peaks by any of the Lookout Peak access points. A trail near the summit of Lookout Peak cuts north to merge into the south ridges of Swallow Rocks Peak.
Sessions Mountains Access
A bit longer route but if you were already climbing Grandview Peak via the GWT on the north via Skyline Drive out of Bountiful, you could add these peaks for a long day trip.
Red TapeSwallow Rocks North Peak is probably on private property as you can see in this Resort PDF Map, but I didn't see any signs along this portion of the hike. I know they are really concerned mostly with hunters since their cliental is mostly recreational hikers and ATVers and they issue there own private hunting permits.
No Dogs Allowed
CampingPutting up a base camp on the north side of Grandview Peak would put 6 or so peaks available for grabs. There aren't many backpacking options in this part of the Wasatch but this area would be one.
