Are there lockers or secure storage at the zipline locations for backpacks and cameras? Thanks.

There were lockers at the ziplines at Hacienda Guachipelin. There were not at Canpoy Safari near MA.

There were also lockers at Sky Tram/Sky Trek in Arenal.

On SkyTrek in Arenal, I wore a small packback with no problem. (The harness goes around your waist and thighs.) You may want to take a small camera with you; we took pictures of each other and the guides were always willing to take pictures as well.

They also someone taking close-up pictures on one of the really short lines which you can purchase but it doesn't capture the long ziplines through the treetops.

At Arenal Canopy Tour the storage area was not secure.

At Selvatura near Monteverde, they had lockers which were secure for an aditional $2 charge, which we used and had no problem. The locers are in the area where you are fitted with a harness and other equipment, so there are always employees there. You can wear a small fannypack while zipping.
