The rapidly growing Newcastle developments are creating back-door
entrances to Cougar Mountain. Park at the entrance to the Meadow
View Trails, and you’ll have a nice view of Seattle and the
Olympics.
Then take a short walk into the park on the Marshall's Hill
Trail, and you’ll find this cache tucked away. Reception can be
spotty, so use the hint and spoiler photo if necessary. Container
is a large Lock&Lock about 30 feet off the trail, but if you
walk carefully, you should have minimal impact on the
vegetation.
