Just came back from Naran a couple of days ago. Jeep trek to Saif ul Mulook is not completely open yet. Jeep takes you to the first big glacier which is 15-20 minutes ride from Naran. Rest of the trek has to be covered on foot or you can hire ponies. Lake is half frozen but melting quickly.
Naran Babusar road is not clear yet either. Work is in progress near Jalkhad so you cannot reach Lulusar Lake yet.
Both Saif ul Mulook road and Naran Babusar Road are expected to open completely in coming 10-15 days. (Naran Babusar road may take a few more days).
Balakot-Naran road is mostly clear. There is no snow on the road (even between glaciers), just some extremely muddy points and a few bad patches.
Hope it helps.
