Dear Mizio,
The starting point to The Seven Lakes area is Panichiste. You can spend the night
at the hut Ivan Vazov. The hut is well maintained and offers food. The price is 15 levs
or 8 eur.
As to the Malyovitsa, there are routes from Malyovitsa hut to the lakes (one is going through the peak
of Malyovitsa, the other is going along the Zeleni rid), but you need one additional day.
The other possibility is to start from Malyovitsa and set off to Ivan Vazov hut, but
you should divert from the route to see the lakes from the top of Otovitsa peak and to continue
to Ivan Vazov hut from Otovitsa.
If you need any further information, I will be happy to provide it.
Veneta Nikolova
