Check out Desafio's website and just fill out the online form to start your vacation plans.

Once you get the confirmation invoices (he will send you one for each activity you signed up), you know that you are good to go!
We scheduled the "Volcano Hike with Baldi Hot Springs" (may 24) and "Canyoning with home-cooked lunch" (may 25). We could have scheduled the SkyTram/SkyTrek with them as well, as we found that prices through Desafio is not inflated compared to if you were to purchase the activities directly from SkyTrek.
Since it is now the rainy season, we were totally rained in during our volcano hike. But Elmer promised lava sighthings with rum cocktail, and he delivered! ;) The Baldi Hot Springs was nice (a bit strange with the loud music), but since the entrance fee is sooo cheap compared to Tabacon, it's a must-go! I recommend that you get it with the volcano hike through Desafio because you would then avoid the extra transportation cost to get to Baldi on a different day. Also, I saw inconsistent (inflated) Baldi prices while walking around La Fortuna.
Canyoning with Carlos was AWESOME! I won't lie, it's scary, but trust me, it's not bad once you've convinced yourself to lower yourself below the platforms. The crew (we had three guides) was funny, professional, knowledgeable. At no time did we question our safety or the quality of the equipment. Carlos promised us a great home-cooked lunch, and he didn't lie! One of the best meals we had in La Fortuna. p/s the ride up to the canyoning start point behind the 4wd pickup truck could cause a little bit of motion sickness. ;)-
We would definitely use Desafio again. All hotel pickups were on-time and in reliable vehicles. The activity groups are in small, manageable sizes for personal attention.
