My husband and I are visiting Chile later this year. We are spending about 2.5 days in Coyhaique. We arrive in Balmaceda airport on a Monday at 17:45 and leave on Thursday at 16:50. We are visiting Coyhaique in particular to see the Marble Caves and to go on an ice trek/hike. We had initially planned on taking the bus from Balmaceda airport South to Tranquilo or another area, but I don't believe the bus times work well with our flights. Should we stay in Coyhaique and take day trips south or should we stay in Tranquilo or another closer area? Any recommendations on specific ice trek tours, private drivers vs. public transportation, and a suggested schedule would be greatly appreciated!
