The Mauna Loa Road to Mauna Loa Lookout is a difficult touring cycling route that offers an unparalleled journey through Hawaii's volcanic heart. Spanning 15.2 miles (24.5 km) with a substantial 2197 feet (670 metres) of elevation gain, this ride typically takes about 2 hours and 15 minutes. You'll experience a dramatic transition from lush, shaded koa forests and kipuka to stark, lunar-like lava fields, culminating in expansive views of the national park and distant ocean from the lookout. It's a challenging ascent, but the ever-changing scenery makes it incredibly rewarding.

Planning your ride requires attention to detail. The paved road can have rough sections and narrows in places, so bright clothing and lights are essential given the presence of cars. Be prepared for rapidly changing weather, from intense sun to cool, windy conditions at the 6,662-foot (2,031-meter) summit, and consider the effects of reduced oxygen at altitude. Always carry sufficient water and check for any park advisories before you go.

This route is a geological showcase, highlighting the dynamic forces that shaped Hawaii. Beyond the dramatic volcanic landscape transition, you can explore features like lava tree molds near the start and the historical rock pavilion at the lookout.

Aliʻi Drive is one of the most beautiful snorkeling spots along the east coast to the east. A stop here is always worthwhile, as the postcard-famous blue ocean and small St. Peters Catholic Church is located here. The best time to cycle through is early in the morning, but during that time it is important be respectful of the surfers who get up early to surf here.

This is a very quiet beach away from all the tourist hustle and bustle. It's not the most scenic beach, but if you value quiet time, this fits the bill. The shores are a little rocky from the lava flows and there isn't potable water, so ensure you are prepared.

Hawaiian Ocean View Estates is the largest subdivisions in the nation! This subdivision is 18-square miles and has about 157 miles of roads. Imagine doing a century ride and never leaving your neighborhood or repeating roads! If you are thinking, that must be terrible for the mailman, luckily they deliver to a main mailbox hub. This land was purchased by Hawaii Volcanoes National Park and is surrounded by lava flow.
