Other hikes I am just now getting around to mentioning:
Stewart Mountain -- Stewart is the ridge that keeps sea-level Bellingham from having unobstructed Mount Baker views. The land is owned/maintained/whatever by a logging company and, presumably, the power company (what with all of the power lines going up, though, and over the hills there).
I followed the logging/access road that heads up the hill from the parking lot at the North Lake Whatcom Park. (Don’t follow the trail directions in the link unless you really want leisurely stroll along the waterside). Walk around the gate and follow the road up the hill. And up. No joke about the ups. The first two miles are killer. At any time you can turn and see views of Lake Whatcom and some peak-a-boo views of Bellingham (trees and power lines may obstruct your view). Eventually the road winds back in through the trees and levels slightly. When you reach the crossroads, go straight (and under the power lines) another mile or so until you reach a Y in the road. Go left. Go up. Stop when you can look down on Acme and out to Mount Baker.
If you go: you’ll be spending a lot of time walking through clear cut, so you may be exposed to a lot of sun. I don't have all of my facts and figures... there may be anywhere from 2000ft to 3000ft elevation gain. Whatever it is,
Oyster Dome -- There are a number of different trailheads for this hike. The hard trail starts down on Chuckanut Drive and zigzags up the hill. The less hard one (the one I prefer) starts on Blanchard Mountain at a parking lot that is also a launching area for hang gliders.
The Bat Caves are the coolest. You can scramble around on top of the rocks or, if you brought a flashlight or head lamp, explore some of the caves created when all of the rocks fell. Careful if it's wet, though.
Instead of my rambling on about it, check out this article from the Seattle-PI. The article is 8 years old, but it's still good.
