Sorry @@Croocodillul. Thanks for your answer! I happen to be in Sinaia with the family (I could't ride) and I say very nice trails up in Cota 1400 and around. It looks just amazing!
Do you know where I can rent a enduro bike for a weekend? Maybe in Sinaia I guess, I am doing a bit of research.
Thank you very much for your offering about going with you guys. For me it is perfect if we can eventually go to Sinaia once, I would love it. And it is pretty close so we can be back in Bucharest reasonably soon.
I am looking forward to ride in Sinaia and Brasov.
All the best and many thanks!
