* It's easy, beach town lifestyle may front as a segue to spiritual enlightenment and bliss, but sprinkle on top of that a dose of perpetual nightlife and heavy drug culture, and you can easily fall victim to the trap.
The key is to keep moving. There are plenty of natural, exuberating things to do in this balmy oasis. For one, surfing. The surf is great for learners, and comfortably warm for just soaking in or body boarding. If you're a diver, you can grab a tour with one of the local diving agencies (there may be two) and have a pretty decent ledge dive and see some stuff.
If it's whale season, which I think starts in July (fact check me), I'd say it's definitely worth a dive, just for the chance encounter. The agency will also 'certify' you real quick in their pool (literally located in one of the bars across the street) if you don't have any experience diving. I don't think I should recommend this.
Not to mention, you can hang out with Cristo Rey himself. They dropped this statue of the guy out there a couple years back to bode off illegal fishing and littering.
There is a zone around that ledge and an island that's now officially protected waters.
They have a real initiative going for environmental conservation, and I think it billows from protecting whale migration routes.
To get Cristo in place, they had to build a sturdy, plank bridge between two boats for him to balance on; and then, slowly navigate out on a calm day (which took 3 hours as opposed to the usual 20-30 minutes), and pray it didn't storm (effective in this case). Although a noble idea, I'm not sure how well it's working--judging by the sketchy fishermen fleeing the scene as we approached.. Makes for a cool photo op though if you've got someone with a gopro.
Go ahead and have yourself a good long weekend in Montañita, but don't fall victim to the perpetual party, and put a picture of yourself on the background of your phone.
