I am on Ometepe island and would like to go to Popoya. Does anyone know the best way to do this? Many Thanks!
by private transfer, as there are not public transfer to this place that run that often.
There are public buses that run every couple hours during the day from Rivas. When you get off the ferry, you just need to snag a taxi, or bike taxi, or walk to the bus station a couple kms away in Rivas.
I believe the bus leaves every 2 hours starting at 9am (9, 11, 1, 3, and 4)

Look for the Tola bus (the one that continues past Tola to Las Salinas de Nagualpa). It will take you all the way up to Popoyo (well, about a half kilometer away, depending on where you are staying)
