This trail is the singletrack portion of the Kirkham Ridge Trail and is a great way to access a number of other loops. The easiest loop to put together is to the take the Ridge Trail to the Link Trail
and then return on the Warm Springs
trail. Putting together a loop with Gates Creek is also a possibility. Or, using the ridge trail to access the Red Mountain Lakes is another option.
Given that this is a ridge, trail there are lots of ups and downs traveling across this mountains range. Also, you'll be moving across different fire landscapes. You can see some of the recent fires from the aerial imagery, so bear in mind that these sections may have more downed trees to climb over the earlier in the season you attempt the trail.
The trail starts at Bull Trout lake simply because it provides better access to the recommended loops. If your goal is to just hike this trail then it might be best to actually hike it in reverse.
