Our second day in Maui we visited Haleakala National Park. This is our 3rd national park for the trip. There is one main road in the park and it's a doozy. Even though we are staying close to the park, I think it was a 2-hour drive to get all the way up to the summit. The drive is nauseating. They recommend stopping for breaks :) Such as this short hike. Haleakala is a volcano which takes up 75% of Maui. It's still considered active but hasn't erupted since around 1600.

Our first stop was the Hosmer Grove Trail. This is a trail that is well known for birds. I found the flowers pretty too. There's a campground at the trailhead. We considered camping there, but I didn't want to lug my camping gear around for this long of a trip with so little camping.

Today we left the Big Island to fly to Maui. I'm sad that we didn't see a full-on volcano eruption. The forecast is that it might erupt today!  And now, writing this at home, they say the fountaining episodes have been increasing in frequency. Now its fountaining weekly! 

We are staying at Peace of Maui, a rental house on the island. We like it. We stopped by a beach. I was wearing hiking clothes and hiding in the shade. Everyone else on the beach was in bathing suits. Dian pointed out large sea turtles on the beach. I've seen them swimming a few times but never hanging out on the beach. It had a sad expression but maybe turtles just don't smile. We didn't stay long because it was so hot. I felt like I could only be either in the ocean or in the shade. The water was beautiful though, and we saw many, many sea turtles in the ocean too.  No hikes today, but I really needed a rest day after being so hot yesterday.

In the afternoon, I went sketching with 3 members of Urban Sketchers Maui. I contacted them last minute, and they managed to round up a few people to come out sketching with me. This was especially lovely, because I volunteer for the global Urban Sketchers group, and I help new groups become official chapters. I had just started working with this group before my trip.

In the evening, we ate dinner at Ocean Distillery, a place which our house rental owner recommended. We listened to live music and watched a sunset. The location must have had some elevation, because we could see both sides of the ocean from where we were. A nice relaxing way to finish off the day.

Captain Cook Monument Trail, Kealakekua Bay State Historical Park

  • Napo'opo Road. Parking is streetside and can be challenging. It's a busy place.

Directions:
  • Take the Captain Cook Monument Trail downhill to the ocean. Return the same way

Dian and I went to hike down to the Captain Cook Monument, where Dian wanted to snorkel. Phyllis took a rest day. This is a 4-mile round trip, with 1,300' elevation gain. We read to leave early. We did, but it really wasn't early enough. This hike has a lot of sun exposure and rocky terrain. I definitely didn't bring enough water for it, forgetting one of my bottles back in my room. I brought a bathing suit, but I didn't make it all of the way down to the ocean. The hike goes downhill for 2 miles. I made it 1.6 miles. The last 0.4 miles flattens out. But I was overheating - and that was just while descending. I knew I'd get even hotter climbing back out. Dian continued to the ocean, and I found a tiny bit of shade & rested a bit. I climbed out. So, so hot, and I had to take rest breaks whenever I found a little bit of shade. I'm bummed I didn't make it all the way down, but glad I recognized I shouldn't be doing this hike without enough water. I did see many people going down with just a small bottle, but for me the heat was too much. 

In the evening, we went for a nighttime snorkel with the manta rays. This was one of my top 2 favorite experiences in Hawaii! Manta rays are huge!!! I was originally scared about swimming in the middle of the ocean at night, but once I watched videos, I realized it was very safe. You don't have to swim far, and there are lights on the boat, so it isn't pitch black. They gave us wet suit tops and ankle floaty things, and we gently stepped from the boat into the ocean, trying always to keep our bodies as flat as possible. You swim out to a long board, and everyone holds on, lying flat. Lights on the board attract plankton, and then the manta rays swim up to eat the plankton. They do backflips right under you - probably 6" from our bodies. They open their mouths and they look big enough to swallow you. But they are very gentle, and I didn't actually feel one (you are supposed to avoid touching them). We saw around 6 of them (several times each). They weigh around 1,000 lbs. and I think are around 10-15 feet wide. So, so amazing! Just do it if you have a chance! In Kona, they say 90% of the time you will see the manta rays on their trips. I have no photos though - you can rent a GoPro for extra money.

No, we don't know how to tie sarongs.

After wandering around the park and doing a couple of quick sketches, we did a hike on the 1871 Trail, where there were way fewer people. This is an out and back was interesting due to having dozens of goats on the trail, sometimes running in front of us. The goats are obviously a problem for the park, as they eat everything in sight. Goats were introduced to the island in 1813. There were gorgeous views of the ocean, plus some caves, which I found out later are actually lava tubes.

On our way back to Kona, we stopped at a random beach to watch a magical sunset.

We hiked to the gate, and then took the Coastal Trail on the way back.







Soooo many goats on this trail. 100+






Stone walls, possibly used to be a goat pen?





I assume these are lava tubes
