We booked a total 9 days trek to Mardi Himal Base Camp with Third Rock Adventures. They helped us out a lot in advance by answering all our questions through emails and provided us with all the information we needed for our trip in Nepal. We also booked rafting and paragliding with them and they helped us to plan everything. Upon arrival at 2 o'clock in the night, because our flight got delayed, they were still waiting at the airport to give us a warm welcome. During our entire stay they gave us tips and helped us with small things like transport and accommodation, even when we were not trekking and were travelling on our own. The trek itself was perfect, everything was well-organised and they made sure we had a great experience. They also arranged other fun things like a farewell dinner with typical Nepali food and souvenirs. I'm very happy I booked with this company! We made some perfect memories from Nepal.
