According to forum posts, Peru offers a variety of bus services including PeruHop, Cruz del Sur, Civa, Transzela, and the 4M Express tourist bus. These services connect major cities and tourist destinations such as Lima, Cusco, Puno, Arequipa, Nazca, and Paracas.

Some travelers mentioned that while PeruHop offers flexibility and covers multiple stops, it is expensive compared to regular public buses. Cruz del Sur and Civa are noted for their comfort, providing options with reclining seats. For budget-conscious travelers, regular buses are much cheaper and are frequently available.

For specific routes, the 4M Express tourist bus is highlighted for traveling from Puno to Arequipa and Chivay. Transzela is another option, though it received mixed reviews regarding comfort and amenities like air conditioning. Travelers have called out that direct buses are available for those who prefer not to make stops en route.

According to forum posts, a guide is not mandatory for visiting Machu Picchu. Some travelers have successfully visited the site without a guide, relying on guidebooks or prior research to navigate and appreciate the site.

However, for those interested in hiring a guide, it's common to find guides available at the entrance of Machu Picchu. Travelers have mentioned that negotiating with a guide at the entrance is typical, with prices varying based on the time of day and group size. Some users suggested that forming a small group with other visitors could reduce the cost significantly.

Despite not being mandatory, several users have pointed out that having a guide can enhance the experience by providing valuable insights and historical context that might not be apparent without one. This is particularly useful since the site lacks detailed signage or information boards.

According to forum posts, popular trekking routes in Peru include the Salkantay Trek, Ausangate Trek, and Ancascocha Trek. These treks are noted for their scenic views and varying levels of difficulty and crowd presence. The Cordillera Blanca region is also recommended for its natural beauty and less touristy paths.

Some travelers have mentioned that the rainy season can impact visibility and trekking conditions, especially from November through April. It is advised to check weather conditions and prepare for possible rain and mud if trekking during these months.

For travelers interested in combining cultural experiences with nature, the Inca Trail and Choquequirao to Machu Picchu via Yanama trek are highlighted. These routes offer a mix of archaeological sites and natural landscapes. Additionally, treks in the Lares Valley are praised for opportunities to interact with local communities and explore less frequented paths.

According to forum posts, the only official way to purchase Machu Picchu tickets is through the Peruvian Ministry of Cultures website, which can be found at www.machupicchu.gob.pe. This site includes options for various entry circuits and ticket types.

Some travelers have mentioned that tickets can be purchased in person in Aguas Calientes at the Ministry of Culture booth. However, these tickets are generally for entry the following day, and availability can be limited.

For those unable to secure tickets through the official website or in person, it's possible to buy through authorized resellers or travel agencies. These agencies typically charge a commission but can provide convenience, especially when ticket availability is low or the official platforms are experiencing technical difficulties.

Travelers have called out recent issues with the official ticketing website, including technical problems and changes in the ticket sales platform. These issues have caused confusion and made it challenging to secure tickets promptly.

According to forum posts, selecting a tour company with a good reputation and local experience is crucial. Travelers have recommended companies like Tambopata Travel and Eco Amazonia for their proficiency in navigating the Amazon region, indicating that these companies offer knowledgeable guides and satisfactory services.

Some travelers emphasized not to opt for the cheapest tour options as these often result in poor service. It's suggested to look for companies that provide a balance of cost and quality to ensure a comfortable and enriching experience.

For a more tailored experience, some users advised choosing smaller, local tour operators that can customize your journey. Companies like Tambopata Travel have been mentioned for their ability to cater to specific needs and preferences, making them a suitable choice for personalized tours.

Lastly, it's beneficial to consult recent traveler reviews to gauge the current quality of service provided by the tour companies. Positive feedback from recent trips can be a reliable indicator of a company's capability to deliver a memorable Amazon tour.

Some travelers have recommended the Costa del Sol Wyndham, which is conveniently located just across the street from Lima Airport. It was mentioned that it might cost around $180 per night. Another option is the Holiday Inn, slightly farther but still close, requiring a brief 5-minute taxi ride, with a nightly rate of approximately $250.

According to forum posts, the area around the airport is not very nice, and while the airport itself is safe, it is advised to stay in these recommended hotels for safety and convenience due to their proximity to the airport. These hotels provide peace of mind, especially for late arrivals or early departures.

Travelers have noted that these hotels, particularly the Holiday Inn, offer shuttle services to and from the airport, which adds an extra layer of convenience for guests. This is particularly useful for travelers looking to minimize hassle upon arrival or before departure.

According to forum posts, there are two primary train companies operating services to Machu Picchu: Inca Rail and Peru Rail. Inca Rail offers an all-inclusive package which includes trains from Ollantaytambo, a bus from Aguas Calientes to the Machu Picchu entrance, entrance tickets, and a guided tour.

Some travelers have mentioned that train tickets can be purchased separately if desired, which might save some money. The cost for the cheapest train can range around $60-70 each way. For those looking for a combined ticket, Inca Rail’s package could provide a convenient, albeit more expensive, option.

Travelers are advised that the train journey plays a significant role in the overall experience of visiting Machu Picchu. Trains usually depart from Ollantaytambo, and it is recommended to book tickets in advance to secure your travel plans, especially during high season or for popular departure times.

According to forum posts, driving in Peru can be challenging due to unpredictable road conditions and aggressive local driving habits. Some travelers have reported frequent unmarked speed bumps, poorly maintained rural roads, and unexpected road closures without prior warning.

Travelers have called out the aggressive driving culture in Peru, noting that local drivers often do not adhere to typical traffic rules seen in North America or Europe. Honking is frequent and used as a means of communication, and it is common for drivers to occupy any available space on the road, which can be disconcerting for visitors.

Forum users have mentioned encounters with police checkpoints and occasional requests for bribes. There is also a mention of security concerns regarding vehicle safety, particularly in less secure parking areas, suggesting a higher risk of theft.

For those considering driving, it is recommended to rent a car with good ground clearance and ensure it is in robust condition to handle the terrain. It is also advised to avoid driving at night and to always keep the vehicle's fuel tank at least half full to avoid being stranded.
