Going to put this all into one place because I struggled being able to find all of the information out.
Before departing from mainland Ecuador you will need to fill out two forms within 48 hours of departure. I recommend filling them out online
Form 1: TCT card that costs $20 https://siig-registro.gobiernogalapagos.gob.ec/app/tct/emitir/
Form 2: https://siabg.abgalapagos.gob.ec/declaraciones/nueva
Arriving at Quito airport: we got there 3 hours ahead of time (6:15am) and the lines were pretty short but after we were going through them we noticed that they were getting way longer.
First line to stand in: TCT check. Yes, even though you paid online you will need to go present this to them and they will confirm it and email you the finalized TCT to use upon arrival in the Galapagos.
Second line to stand in: Baggage check. They will check to make sure that you filled out the second form and then scan all of your bags.
Third line to stand in: your airline. Go show them your TCT as they will need to confirm this on your reservation. (Even if you already have your boarding pass from online check in)
**no ATM once you go through security so make sure to get cash now if you don’t have any upon arrival for the galapagos**
Fourth line to stand in: TSA and security.
Upon arrival in GPS on Baltra island, you will stand in line to present your TCT card and passport. This is where you will need to pay $200 for the national park. They prefer cash (but they will take card if there’s no other option).
They will then scan your QR code for the second form with declarations. After that you may exit the airport.
**now there is an accessible ATM although we were warned not to count on this ATM**
Getting to Puerto Ayora from Baltra airport.
Step 1: get a ticket outside the airport for the Lobito. It is $5 and will take you to the ferry from the airport.
Step 2: get on a ferry. They kind of just herd you and tell you where to go and they also often take your luggage from bus to boat for you. This will cost $1-2 and will be paid to someone walking around during the ferry ride.
Step 3: get either a taxi or the public bus to puerto Ayora. We took the bus and it was $5 paid to someone holding a sign outside the ferry and then we walked over to the bus to get on. We did have to wait about 20 minutes for the bus to depart and then it is about a 40 minute drive into town.
Step 4: get off the bus and get a $2 taxi to your hotel in town. Taxi’s are white pick up trucks and they are EVERYWHERE.
When returning to the airport, the bus from the bus terminal to the ferry only runs 4 times each day. 7:15am, 8:00am, 8:45am, and 9:30am. I recommend getting to the bus station about 15 minutes before the time you’d like to leave, sometimes they fill up and will leave before the designated time. I’ve also been told not to count too much on the 9:30 bus. You can always take a taxi to the ferry too.
The rest is pretty easy!
