Getting There: At the top of Thompson Pass take road #266 on the Idaho side of the pass up past the vault toilet for about a mile to the small parking area at the trailhead. The road is passable for any vehicle, but there is no room for a trailer. The trail takes off at the end of the road/parking area. 
The trailhead is not very big and being located just off Thompson Pass tends to fill up fast on the weekends. This is a very popular destination so a mid-week visit provides some level of solitude. One weekend day, we counted over 50 people on the trail and we were back to the trailhead by noon. This is an easy 1.5-mile stroll to the lake with a small creek crossing at the halfway point. The trail is in really good shape with modest grades to the lake. There are no significant side trails that connect into the main trail. This is a good casual hike or camping trip for a family with younger children or for the first overnight backpacking.
At the Lake: There are several campsites on both sides of the outlet and a couple others close to the inlet stream on the far end of the lake. You can probably squeeze in more than 10 parties into the various campsites if needed. There is a nice little beach on the far side of the lake with a fire pit along the lake. Compared to the trail to the lake the lakeshore trails on both sides are quite rough, steep and has a few deadfalls across the trail. I have only fished this lake 1 time and did not do very well at all.
In 2023, my son (Colter) and I completed the Thompson Pass Loop and came into the lake at the outlet. The campsites at the inlet were full but there were still a couple sites near the outlet available.
