When visiting Chiang Mai, it's essential to stay connected and respect local customs. Many guesthouses, hotels, cafes, and restaurants offer Wi-Fi, and the city has over 3,000 free Wi-Fi hotspots, allowing you to stay online easily. For mobile connectivity, remember that Thai mobile numbers have 10 digits, including a leading zero. As for transportation, the RTC Chiang Mai City Bus system is a convenient option, with routes connecting to Chiang Mai Airport. Additionally, songthaews, or red trucks, are a popular way to get around the city, with fixed prices for rides within the city walls. It's also important to drink bottled water, as tap water isn't safe for consumption. Most restaurants use ice made by professional companies, which is generally safe. Lastly, dressing modestly is appreciated; covering shoulders and wearing long pants or medium-length skirts will help you blend in with the local culture. By keeping these tips in mind, you'll have a more enjoyable and respectful experience in Chiang Mai.
