After booking a stay at Seabrook I was very excited to learn Evergreen has built trails right in the town! Someone has very diligently gone and marked them all one-way due to Covid-19.
Unfortunately this has made it kinda hard to ride narnia because it's really not obvious where the entrance is (it's at the highway): the full trail isn't marked on trail forks or on google maps, but you can see it here on openstreetmap:
Narnia definitely lives up to its name, really pretty. It gets a small amount of hiker/jogger traffic, so it's good that it's doubletrack for most of the length. There's a part in the middle that has been de-forested and is a fairly rough logging road, but the rest is fun doubletrack.
Mike-o-rama has a great view of the beach and is a lot of fun, I just wish it was longer. You can do laps though.
Groot is well named. Too many super wet slippery tree roots for me, I ended up walking most of it.
Zipline is right in the middle of town and lots of fun. Most of it is pretty slick clay in the wet though: was a bit too scary for the kids I tried to take on it. I was hoping it might be more like bootcamp at duthie, but it's a step up from that.
We had tons of rain, but all the trails drained pretty well: kudos evergreen!
