Hi Steve
Yes the Arnold Rim Trail is long! You can see the homepage at
http://arnoldrimtrail.org
Go to the “Trail Info” page, and you will see an overview map with 2 inset blow-ups of the most popular loops — the San Antonio Creek loop of 5 miles, and the Cowell Creek Loop of 3.5 miles. Both have parking areas in town.
I usually use the trailhead at the Logging Museum, especially if I am taking guests and we go through the museum before or after. The first segment of this part is paved and very accessible, with some interpretive signs. You can also take a dip in the lake afterwards!
Most of the single track trail has a firewood running more or less parallel to it on the town side, which you will see a few places. This can be used as a bail-out route if the loops get too long (though they are not really scenic).
The coolest parts are the “Top of the World” which is a ridge with views in all directions, and “Cougar Rock”. A couple of waterfalls are also possible to visit with side spurs.
My favorite time to go when the Dogwoods bloom. The whole forest understory explodes in flowers and even a short trip is amazing. Falls colors are also great and coming up soon.
Enjoy & let us know what you think!
