My dos colones......
Elwayyy,
Since you're going to be near the coast, I'd recommend the White Water Rafting. There are several different WWR day trips available, and can be booked from just about any hotel in SJO.
The Canopy tour is great, but it so damn hot. You're in the jungle, and the trees are thick, and there is no breeze, thus making you sweat your ass off! It's a great time, but hot as hell. On the other hand, it's a great cardiovascular workout!
The ATV's are fun, but as Orange stated, you'll get muddy and grungy, especially since you'll be doing it during the rainy season. And you'll end up shit-canning your clothes from the day. And if you're not used to riding them (ATV's), it's real easy to lose control, and drive off the side of a mountain! But it's definitely a great time!
On the WWR trip, you're in the water, and you're travelling down the river. If you're hot, just jump in (in a calm area) and cool off. You'll be doing quite a bit of paddling, so it's a good workout also.
All 3 trips are a lot of fun, so it's up to you. But me, personally, I like to have the ability to cool off when I get hot and sweaty!
Whatever you decide to do, be careful and have fun! You'll be happy that you got out of the gulch, and tried something different, besides sport-phucking! (although that's a pretty good cardio workout also)!
Mucho Gusto
