I spent January, February and March in Ecuador 20-some years ago. I got rained and snowed off of about 6 volcanoes. And I mean downpours. Summited only on Tunguruaha. At that time on that peak I needed my crampons for only about an hour. The rest was scree up high, jungle below. That snowfield is likely all gone now on Tungu., it's 16,000 ft.
The flight to/from Galapagos from Quito was cheap, and I got the white knuckle thrill too - thunder and downpour flying back into Quito circling above the airport while I could see the jungle covered volcanoes jutting up into the clouds. The snorkeling around Galapagos was good. Good surfing and cool travelers beach at Manglaralto.
