Finde Stavanger-Bergen-Stavanger

I want to do three things. But my fligth will arrive on friday nigth in Stavanger not in Bergen.

1. Go to the Fiords of Bergen side on Saturday.

2. Walk in Bergen on Sunday during the day

3. Be back in Stavanger in sunday nigth

The point is that on monday we already have the reservation to the puplit rock, so changes are not allowed.

May you can advice me ?

Best regards.
