We had a wonderful time at Vacasa Hawaii. The accommodations were exactly what we needed: clean and welcoming and cool at night.
The house is walking distance to Kapena beach which has fine black sand (a lot of other beaches are moderately rocky). The only challenge is traversing the rock path down the beach from the road. It might not be accessible for very small children or those with any mobility issues. Also check out the Isacc Hale beach park (2.2 miles/10 min drive) with a lava warmed tide pool. It's a must for young children and older visitors. Come after 3pm as the warm tide waters and tropic temp cqn be overwhelming.
A car is a necessity for the location as public transportation is limited and nearly all destinations are much longer trips because the road system accounts for maintaining the natural beauty and lava rock since the 2018 eruptions. It's 20 min drive to Pahoa which has everything you might need. It's 1 hour from Hilo which has lovely shopping. Go the Saucy Dog for polish, vegan or traditional dogs and buy a ukulele while youre in Hilo.
The welcome book at the house needs to be updated as a few of the destinations are no longer there since the 2018 eruption.
We would come back in a heartbeat.
