On occasion parts of the Kalalau Trail is closed to visitors. Sometimes this is due to trail maintenance or a planned event like it was last summer for the feral goat and pig hunt. When these planned events happen, the Department of Land and Natural Resources (DLNR), Division of State Parks does not issue permits during that time period. This can be disappointing if you were planning a trip for that time period but at least you can find out ahead of time that there are no permits available.
There are several stream crossings along the Kalalau Trail. These water crossings can be a great place to take a break, fill water containers and canteens or even cool off by taking a dip. While most of the time the streams are a blessing, they, like most other things, can have their negative side. During or following a big storm, these streams can swell up and become raging rivers. They aren’t the harmless oasises that they usually are, but rather they become dangerous, sucking torrents of water that can injure or imperil hikers.
