Tevevaka on Dec 24, 2014 from Ahu Akivi, marked trailhead to the right side of parking area. Rano Kau on Dec 26, 2014 from Ana Kai Tanata. The high point of Rano Kau is on the east side of the crater, not on the Orondo side. Trip reports to follow with more details.
Nice climbs & good views Date Climbed: Feb 18, 2008
Maunga Terevaka: Feb 18th 2008. We had Terevaka to ourselves - the island's highest point seems much less popular than the other sights on the island. We hired a scooter and drove to Ahu Akivi, and climbed from there in 1 hour.
Rano Kau: Feb 13th 2008. Excellent half day hike from Hanga Roa, the view from the mirador was stunning.
Maunga Terevaka: November 6, 2005. Visited from Ahu Akiva and returned by way of the west coast (on foot). Unfortunately, the battery in my digital camera died, so I didn't get any pictures. This was too bad, since I found lots of interesting stuff that is not visited by the tour groups.
Rano Kau: Climbed on November 5, 2005 with my wife and kids via Hanga Roa. Great hike!
