I used to live on north Beacon Hill, where one of the entrances to the bike path starts at Daejeon Park. In Daejeon, South Korea, you can visit our city's sister park "Seattle Park." Kinda cool, huh?
Back to the I-90 trail; this is yet another great bike and foot path that provides easy access to users, fine paths, and great views. No sooner do you start on the Seattle side of I-90 bridge, and head through a graffiti-painted tunnel, then you're on I-90 itself, running alongside the traffic to your right and boats on your left.
But, not being a street bicycle rider, I use this path mostly for marathon-distance training. It's pretty flat for most of it and you get the option of exiting onto Mercer Island before circling back across the bridge.
It can sometimes be pretty breezy, and I highly recommend only running on I-90 early in the morning (the car exhaust can be a little much otherwise) and if you have ANY kind of spider phobia, I don't recommend this path for you. In between the narrow metal railings of the entire length of the bridge, are hordes of spiders on their spiderwebs. On windy days, the webs balloon in/out depending on which way the wind is coming in. I think it's beautiful--gossamer threads billowing; the spiders looking like they are on the best roller coaster ride ever. Others might see it as a corridor full of nightmare fodder lol
The bike path is great for walking/running/riding by yourself, with friends/family; and if you are bicycling, pack a backpack picnic :) read more
