4 /5 Carli (Adventures with Carli): Trail is pretty steep for first .75 miles towards the lakes, then evens out. Signage could definitely be improved. hike was very pretty and will be even better in a few weeks once larches are in full shift.
Clara Lake is the bigger and more impressive of the two. Marion lake requires climbing through more loose rocks and is smaller of the two lakes.
If you don’t like screaming children during your hike, strongly recommend going during the week rather than a Sunday. At one point had unattended small children screaming and running down the trail past me with parents just casually walking well behind them up the trail.
Parking lot is limited and people park pretty terribly so you may need to get creative. But no pass required.
No toilet facilities in the area.
