Maui Mountain Cruisers is now
A highlight for most visitors to Maui—if not all of Hawaii—is experiencing a guided bike tour down Maui’s active volcano – Haleakala. Guests can enjoy this experience in an active way. Bike 26 miles (42 km) from the 6,500′ all the way down to the the beach town at Paia. Tour begins with pickup in the early morning from hotels (fee applies) in the Maui resort areas such as Wailea, Kaanapali, and Kapalua for the drive up to our office/base-yard where we will start guests off with a hot or cold beverage and a snack.
From our office, we will transport guests to the 6,500′ level and your tour guide will provide you with the history of Haleakala, its geology, and the rare plants and animals found only on Maui. Watch the predawn colors from this location, and then you’ll be fitted with a bicycle and helmet to start your guided bike ride. Coast downhill, riding along switchbacks, through Haleakala Ranch, and past Kula. Continue through the towns of Makawao and Paia, and finally reach the Pacific coast at Paia Beach town.
1. We scheduled to be picked up and they claimed it would be an additional $100 for the two of us even though their confirmation email said we would be picked up. This happened to another customer. MMC blamed the booking agents, although I booked directly with them.
2. There was no snack or hot beverage provided.
3. Transportation to the biking location was sketchy! The van had low tire pressure and needed an oil change. The driver rode the cars in front of him and passed two vehicles up hill on a windy road, crossing the double yellow. This was even after being told that some of the passengers were prone to carsickness. One passenger got so sick that she could not do the bike ride.
4. The content from the guided tour was only about the Baldwin family coming to Maui to save the natives from the diseases contracted from the white people and that the descendants of the original Baldwin are all broke now.
5. The bikes and helmets were in extremely poor shape. There were not enough helmets to fit properly. Brakes were squishy. One of the bikes we used had a bulging tire and wobbled.
6. We only had a driver. Not two guides. The bike ride down was not guided. This was a self guided tour, even though we paid for the guided tour.
When confronted about these discrepancies, the driver passed the buck to the outside organizations who book the tours, not taking accountability based on their website.
