Hello. I just checked the Plataforma10 website and see that there is a 08:30 TAQSA bus from El Calafate to the Perito Moreno boardwalks on November 9 with an arrival at about 10:00, with a return from the boardwalks at 14:30 for an arrival back in El Calafate at about 16:00. I then see a Chalten Travel bus leaving El Calafate for El Chalten at 18:00.
Since you would miss the 08:30 bus to the glacier boardwalks, you could try to get a taxi like Remis Condor to take you to the boardwalks and use TAQSA for the ride back.
You can also use Las Lengas for a direct transfer from the El Calafate airport to El Chalten. When you finish hiking in El Chalten, you can then take a bus back to El Calafate and, hopefully, have a full day to explore the Perito Moreno glacier before you leave El Calafate.
Hi again. I see that Patagonia Chic is offering a tour that leaves El Calafate at 09:00, but I'm just not sure if you can reach downtown El Calafate by that time. You have to allow time to get off the plane, get your luggage, and take a taxi to the place in El Calafate that would pick you up for the day trip to the glacier. Maybe you can contact Patagonia Chic through the link below and see if they can help you? Good luck.
CaliforniaElizabeth, you are so helpful! I'll contact with them and sort it out. Thanks!
