10. Mauna Kea
Location: Hawai’i Volcanoes National Park, Hawaii
Elevation: 13,796 ft / 4,205 m
If you like having beaches in the nearby and combining highs with the lows, go to Mauna Kea. It’s the tallest Hawaiian mountain, but it’s not as difficult as it sounds. Rather than having one peak, we could say it has several tops. Humu’ula Trail is what we would recommend. This is more or less the highest mountain you can walk up.
