Bartolomé Island, in the Galapagos, has a boardwalk from the ocean to its peak, including almost 400 steps. Partway up the boardwalk, I took this picture looking back at the lower section of the trail. That is a lava cactus in the foreground, pretty much the only one we saw on this barren landscape.
This is a picture of the lower section of the boardwalk on Bartolomé Island in the Galapagos. You can see a Panga boat docked, having just let off some tourists.
A middle section of the boardwalk on Bartolomé Island as it winds its way around and up. That is part of our group climbing the stairs.
