We really really loved it! Our hotel recommended this tour instead of eg. Selvatura because of the small groups. We'd read that the wait times at the more extreme canopy tours could get really long and irritating, and we weren't fussed about the superman lines. We just wanted some adrenaline and some great views - and it's what we got.
Our guides, Josue and Tuca (sp?!) were lovely, chilled out and made it very fun. There are lots of lines - the half mile zipline had the most gorgeous view. We were in a group of only seven, us included, so we had a nice time getting to know the group while still speeding around the course. Really recommend this tour, unless you're really keen to do *the most* extreme lines possible in Monteverde, this is the perfect mix between high-adrenaline lines (I'm not scared of heights at all but was getting a bit hysterical), amazing views of the forest, and a genuinely fun morning with a small group.
Admin: They have free lockers there for your stuff, and take photos of you on the way around so you don't need to carry anything with you. Photos cost $10pp or $15 for two people. We wore trainers, leggings, long sleeve tops and light rain macs and were perfectly comfortable. You can go to the loo at the start and end of the tour, which took about 2 hours or so.
Thanks guys!
