Boundary Creek Trail is best used as an uphill to access Little Casino
, Big Casino, or Warm Spring Meadows. Using this trail can create some very large loops with lots of variety.
The trail itself is a steep climb. The trail has a lot of switchbacks and can get loose during the end of the season. Settle in for the long climb and stop along the way to catch your breath and take in the views. The trail starts in heavy trees and then becomes more open as you near the top, so it is best climbed in the morning during the hot summer months.
