Although Hoi An is perfectly walkable, cycling is an easy way of getting around, if your itinerary extends beyond the Old Town (including An Bang Beach). The Hoi An Old Town is closed off to all motorised traffic (including motorbikes) on most days, between 8.30 and 11.00 and then again 15.00 to 21.30, which means streets can be comfortably navigated by cyclists and pedestrians. Many hotels and guest houses offer bike rental services (or even complimentary bicycle use in some cases), but multiple bike rental shops operate throughout town as well. Prices are normally very reasonable and can be as low as 1 USD per day (depending on the bike). Single-gear bikes will suffice for cycling through town, but mountain bikes are recommended for those who wish to venture into the countryside. While locals will often be seen riding without helmets on, we recommend asking for one at your bike hire provider to ensure safety.

Enjoy one of the weekly wildflower walks in the summer or one of the many other activities, including classes for adults and children. The Botanical Gardens provide information on gardening and teach the larger ecological interrelationship of plants and animals in the region.

A favorite daytrip destination from Costa Maya, the Chacchoben Maya ruins are located nearby a city of the same name only 50 minutes away from the cruise port. This fascinating landmark is estimated to have been inhabited since as early as 1000 BC, and after a fairly late discovery in the 1940s, it still contains several unexcavated areas. Visitors can pick from a range of tour operators to be guided through the site, and as a bonus can admire the remarkable flora of what is called the "Region of the Lakes."

Under the shelter of lush rainforest, the archeological site of Kohunlich is an outstanding example of Maya architecture. Palaces, citadels, temples (such as the top attraction Temple of the Masks) and other elaborate structures are scattered over an area of more than 20 acres, with most landmarks dating back to as early as 250 to 600 AD. Chetumal is a common starting point to visit Kohunlich, but tours are available at the Costa Maya Cruise Port, too.
