Issaquah - Preston Trail (High Point Connector)

 The western trailhead branches off from the East Lake Sammamish Trail just north of the I-90 overpass. The trail is paved on its western side, and parallels the freeway, crossing Front St. near the freeway entrance. The trail is fairly level until you reach the end of 1st Ave, at which point the grade increases to about 7% for a short time. After this short burst of elevation the trail climbs at a more gradual 2 or 3% grade. This trail crosses through a tunnel under the Issaquah Highlands bike trail that heads up to the Plateau. The main trail continues on to the left with a gravel/ dirt surface, passing through the woods as it parallels I-90. The trail crosses a small bridge and anti-car gate at a gravel parking lot next to 270th Ave SE. On this section of trail you are about as likely to see deer as people. A new extra mile of gravel trail hugs the side of the freeway and provides an alternative to narrow 270th Ave. Trail signs call this the "Issaquah - Preston Trail" although some older articles/ maps call it "Issaquah Creek Trail" or "Issaquah - High Point Regional Connector".

Looking back west at the retaining wall next to a drainage pond.

The trail parallels 1st Ave NE for awhile.

At the end of 1st Ave NE, the bollards signal that the climb is about to begin.

A leafy wall and a view of Tiger Mountain in the distance.

The approach to Sunset Boulevard's crossing over I-90.

The high road to the Issaquah Highlands branches right, Preston-bound traffic to the left.

After the tunnel, the paving peters out in favor of a dirt/ gravel trail

The western mile of the trail winds through shady woods.

Peekaboo views of Issaquah Creek abound. Rushing water sounds battle car noise.

The eastern trailhead at High Point. There is a gravel parking lot here. The end.

…Or is it? A new trail extension will start construction soon across the street.
