This loop in Beaverton connects three parks with street walking in between. The walk begins at Sexton Mountain Park, once an old quarry, then the site of an underground reservoir, and now housing a park and solar panel array. From the park, you'll hike up to the top of Sexton Mountain to get views from the surrounding hills to the Cascades and Mount Hood. Finally, do more street walking to loop over to Hyland Woods Natural Area, a 30-acre remnant block of mixed woodland that is laced with trails and serves as a quiet haven in a quiet neighborhood. The trees here are up to 80 years old and form a dense canopy over a varied natural understory. A nature play area allows kids to go off-trail and get messy in the natural environment.

From the parking area on the south side of Sexton Mountain Drive, take a paved road that leads up past a gate. The path curves around with a lawn expanse with playground and picnic tables to the left. Keep straight at a four-way junction, There's a blue-roofed maintenance building on the left and then a fenced field of SunEdison solar panels. Take the wide paved path leading right, and make a left on 148th Terrace. Keep on this street for one block as it curves to the right to meet Citrine Loop. Stay straight here, and walk around a bend, go a block, and around another bend, you'll notice two trails, one after the other, marked for Matrix Hill Woods. If it's a good day for views, take the second trail, which leads up to the summit of Sexton Mountain, an outcropping of the Columbia River Basalts (Grande Ronde member). There are two viewing areas with benches, and summit is partially shaded by Douglas-fir, red oak, and madrone. Looking straight south, you'll see the forested ridge of Bull Mountain, split by a powerline corridor, in the foreground, with Parrett Mountain behind. There are also views to the east, with Mount Sylvania most prominent and Mount Hood on the skyline. To the northeast are Cooks Butte and on the Cascade crest, you may be able to make out the distinctive shapes of Table Rock and Rooster Rock. Due north are the Tualatin Hills, with their communications towers, and you may pick out the snowy crest of Mount Saint Helens.

When you've had your fill of views, return to Citrine Loop and walk a few yards to the left to take a paved trail that drops and switchbacks above a meadow that blooms with ox-eye daisies in late spring and summer. You will also get a view straight across to Cooper Mountain. At a second switchback, a user trail leads right through the woods to a grassy slope planted with ponderosa pines and a more secluded view to Cooper Mountain. Back on the paved trail, keep walking down past a spreading big-leaf maple, oaks, and ponderosa pines. When you reach a cul-de-sac on 149th Place, keep straight to walk down past large suburban homes to reach Beard Road in about four blocks. Make a left on Beard and, after one block, turn left on Gordonite Drive. This road curves right to crosswalks that lead to a Walmart store. Turn left into Walmart's parking area, and continue north in front of the store until you reach the junction of 147th Terrace and Maverick Terrace. You can look up to see the much quarried blast face of Sexton Mountain. From the junction, bear right on Maverick. In a block or so, you'll cross Murray Boulevard to continue on Maverick as it curves around, with the Sorrento Bluff Apartments on the left and suburban homes on the right.

Maverick will eventually reach a T-junction with Sexton Mountain Drive. Straight across is the signed entry way to the Hyland Woods Natural Area. Enter the forest at a split-rail fence and a coyote warning sign. At a junction, go left to begin the saunter around the perimeter. Alders, Douglas-firs, hazel, big-leaf maples, trailing blackberry, Oregon grape, thimbleberry, snowberry and sword fern make up the leafy forest. The lack of non-native species is quite remarkable, and there are ongoing projects to eliminate all invaders. Keep going around the perimeter, even noticing one or two madrones. Paths go right into the middle of the woods and also left to the neighborhoods. Go right at the 142nd entryway. The trail winds up and then down in Douglas-fir forest. Reach a four-way junction at the 139th entryway. Keep straight here through an ash swale. At a junction, make a left and then continue straight around a small artificial pond which breeds northern red-legged frogs. The trail heads up for a few yards (to your right, at this end of the park, is the new nature play area, designed for children to get down and dirty with the wild). At a junction, turn left and then right at the next junction (before S.W. Davies Street). Keep straight to continue along the perimeter. The trail rises gradually. At a crossroads, keep straight again. At the next junction, after a madrone, make a left and exit the park the same way you came in - at the Hyland Woods Trailhead. Walk down Sexton Mountain Drive, passing a large open area on your left, to cross Murray Boulevard and reach your vehicle.
