We had a small problem when it came time to leave Santa Theresa - my moneybelt with my passport and most of my cash was in the lockbox and the hotel, but the owners had both been unexpectedly called away that day, and nobody else had a key. If we had been leaving the country that day, this would have been a serious issue, but as it was Dave and I were planning on just travelling 20Km down the road to Montezuma for one more night on the coast before heading inland. So we worked out an arrangement whereby someone from the hotel would ride over the next morning with my moneybelt before we left for our puddle-jumper from Tambor back to San Jose.
In Montezuma, we trundled down the road to look at the waterfall, ho-hum...

At 11:30 I called to confirm that someone had already left to bring over the moneybelt and was told we should expect her at noon. 12:15 rolled by, and then at 12:30 I called again but nobody knew where she was or why she hadn't already arrived. Then the taxi driver showed up and started grumbling about how we needed to pay him extra for waiting around. Finally at 1pm, my moneybelt arrived - she had fallen off her motorbike and had then hitched a ride with a friend who had passed her on the road.
After this excitement, it turned out that we had plenty of time for the plane, as the flight had been slightly delayed by an emergency landing earlier that day at the main San Jose airport which had closed the airport for a little while.
Back in San Jose, we picked up our little Isuzu 4x4 rental easily enough and nipped up the highway to San Ramon where we stayed at the bizarrely luxurious Hotel Pasado where we enjoyed our first hot shower in over a week and had all our laundry done for $5. It was very pleasant to be cool enough again (because of the altitude) to wear long trousers and to have clean clothes.

A couple of hours up the road the next day (over a few dodgy looking bridges) we rolled into La Fortuna, which was mobbed by tourists. The Arenal volcano itself was shrouded in cloud, although still suitably barren looking. Signs periodically reminded us that we travelled everywhere at our own risk (previous eruptions had wiped out whole towns in this area).
We visited a butterfly park in the morning and looked in vain for the tiny venemous frogs that apparently were there. We did get a look at the Fer de Lance snake they had in cage although it didnt really live up to its reputation curled up motionless at the base of a big leaf.
To complete our day, we treated ourselves to the delightful Tabacon Springs (
