The best time to visit Mongolia is from June to September when the weather is mild and suitable for outdoor activities. July and August are peak tourist seasons, offering pleasant temperatures and clear skies. However, these months can be crowded and more expensive. June and September provide a good balance of comfortable weather and fewer tourists. Winter visits (November to February) are possible for those interested in unique experiences like the Eagle Festival, but temperatures can drop to extreme lows.

Most visitors to Mongolia require a visa, but some countries have visa-free agreements for short stays. Citizens of the United States, Canada, and most European Union countries can obtain a 30-day tourist visa upon arrival at Chinggis Khaan International Airport in Ulaanbaatar. For longer stays or entry through land borders, you'll need to apply for a visa in advance at a Mongolian embassy or consulate. Always check the latest visa requirements with the Mongolian Ministry of Foreign Affairs or your nearest Mongolian diplomatic mission before planning your trip.

It is not recommended to drink tap water in Mongolia. While the water may be treated, the quality can vary, and the pipes used to transport it may not be in the best condition. To avoid potential health issues, it's best to stick to bottled water, which is widely available throughout the country. If you're traveling to remote areas, consider bringing a reliable water purification system or water purification tablets. When staying in ger camps or rural areas, always ask about the water source and whether it's safe for drinking.

Accommodation in Mongolia varies widely depending on your location and budget. In Ulaanbaatar, you'll find a range of options from luxury hotels to budget hostels. Outside the capital, particularly in tourist areas, ger camps are popular. These camps offer traditional Mongolian yurts (gers) equipped with basic amenities. In more remote areas, accommodations may be basic guesthouses or homestays with local families. When trekking or horse riding in the countryside, camping is common. It's advisable to book accommodations in advance, especially during the peak summer season.

Transportation in Mongolia can be challenging but adventurous. In Ulaanbaatar, taxis and buses are readily available. For intercity travel, domestic flights connect major towns, while trains run along the main rail route. However, to reach many tourist sites and rural areas, you'll need to hire a 4x4 vehicle with a driver, as roads are often unpaved and navigation can be difficult. Organized tours are a popular option, providing transportation and logistics. In some areas, horseback riding is a traditional and exciting way to explore. Always plan your transportation in advance, especially for remote destinations.
