This was our favorite land tour we did in the Galapagos! If you are expecting to go on a well maintained/paved tour route this is not the tour to go on, but if you want a more rustic and natural experience we highly recommend this tour! We left the facilities walking a narrow, one person trail that leads through the grassy areas/mandarin trees where we saw many tortoises that ranged from small to very large. These tortoises are not in enclosures and are roaming free between the Galapagos Frontier and National Park. We continued on towards the lava tunnels walking through many areas with native vegetation that Caesar stopped to tell us about medicinal uses, etc. Parts of the trail did get muddy, though mud boots were provided. At the end of the trail are the lava tunnels where we saw underground lava flows, fissures, etc. Then we made our way back to the facilities and enjoyed fresh juice which was a great bonus! Book this tour - you won’t regret it!!
