According to forum posts, the Grand Mosque and the Muttrah Souk in Muscat are recommended historic sites. The Grand Mosque is noted for its architectural splendor and spiritual significance, while the Muttrah Souk offers a traditional market experience.

Travelers have called Nizwa a key historical area, suggesting visits to the Nizwa Fort and its souk. Although missing the goat market due to scheduling conflicts might be disappointing, the fort itself is a significant attraction.

For those interested in broader historical experiences, some users mentioned the importance of visiting date plantations and the Bait Al Luban for an authentic Omani dining experience, which also reflects the local culture and history. Another recommended site is the National Museum in Muscat, which provides insights into Oman's rich history.

According to forum posts, major rental companies like Europcar and Sixt generally do not rent to individuals under 25 years old, though some may rent to those aged 21 at a higher rate. No reliable rental companies were found that rent to individuals under 21, as it could lead to driving without insurance in the event of an accident.

Some travelers mentioned that when renting a car in Dubai for travel to Oman, it is essential to confirm with the rental company if they allow border crossing and to understand the associated costs. Additional insurance for driving in Oman may be required, and typically, the car must be very well insured only for third-party damages in Oman.

For those unable to drive themselves, hiring a car with a driver in Oman typically costs over 100 OMR per day for a 4x4 with a driver, including overnight stays. Options like Otaxi or Hala are suggested for more budget-friendly rates, approximately 30 to 40 OMR one way to main attractions.

According to forum posts, Oman still offers a Visa on Arrival (VoA) option for eligible travelers, including British citizens. This is available at the Muscat International Airport and can be accessed at a designated Visa counter before passport control.

Some travelers noted that it is cheaper and time-saving to apply for an eVisa in advance through the official Royal Oman Police website. However, for those opting for VoA, the process at the airport is reported to be straightforward and quick. An immigration officer will stamp the passport, usually without requiring additional paperwork if the stay is under 14 days.

The Visa on Arrival can be free for stays less than 14 days for travelers from certain eligible countries. For longer stays, there is a fee, and you may need to apply for a different type of visa or extend the VoA while in Oman. There is also a mention of a one OMR charge for a walk-up visa.

There is no consistent requirement for proof of health insurance or hotel bookings mentioned across the posts for obtaining a VoA. However, travelers are advised to have their travel itinerary ready to show their departure plans from Oman.

According to forum posts, Oman features good roads that are easy to navigate, making self-driving a popular choice among travelers. It's mentioned that driving to specific locations like Anantara Al Jabal Al Akhdar Resort requires a 4x4 vehicle due to regulations, although the roads are well-paved and straightforward.

Some travelers have expressed that while the road conditions are generally good, having a local driver can enhance the experience by reducing the stress of navigating unfamiliar terrain and providing local insights. The cost of hiring a driver for a day was quoted at 90 OMR, which is considered reasonable by some users.

Travelers have highlighted the importance of carrying an International Driving Permit (IDP) along with a national driving license, especially when planning to visit areas with specific vehicle requirements like Jebel Akhdar. Safety in driving is emphasized, with Oman being noted as a safe country for road trips.

According to forum posts, there is no direct bus service from Muscat to Ras al Khaimah; travelers must go to Dubai first. Some travelers mentioned that the Mwasalat company might still have suspended services, while another bus company, Al Khanjry, operates between Muscat and Dubai, departing Muscat at 3 pm daily and from Dubai at 6 am daily.

For those preferring to drive, one user shared their plan to travel from Dubai to Muscat by car, seeking advice for the journey.

There is also discussion about the feasibility of flying as an alternative, especially given the high cost of one-way flights from Muscat to Dubai around peak times like New Year. However, specific flight prices and schedules were not detailed in the posts.

According to forum posts, travelers seeking taxi services in Salalah do not have many options for public transport to areas outside the city. For traveling within Salalah or nearby nature spots, it is recommended to rent a car or hire a driver/guide due to the limited public transportation.

Some travelers have mentioned the necessity of renting a car for convenience and cost-effectiveness. Although specific taxi services were not highlighted, the general advice is to arrange for a personal vehicle or a guided tour, especially if planning to visit locations outside of Salalah's city limits.

According to forum posts, accessing Jabal Akhdar requires a 4x4 vehicle due to the terrain, and it's mandatory to have one to reach the area. Travelers have mentioned that for those without their own 4x4, taxis or local drivers are available at checkpoints like Barkat Al Mouz to take visitors up the mountain.

Some travelers have recommended staying at high-end resorts like Anantara Al Jabal Al Akhdar for a luxurious experience. For activities, Jabal Akhdar offers stunning views and is suitable for hiking and exploring local villages. The area is also known for its rose factories, which can be an interesting visit depending on the season.

For many users, it's suggested to arrange transportation and accommodation in advance to avoid inconveniences. Checking local conditions and ensuring a capable vehicle for the terrain can enhance the travel experience in Jabal Akhdar.

According to forum posts, if you're staying in Muscat, the W Hotel and Grand Hyatt are recommended for their proximity to restaurants and nice walks along the beach. The Royal Tulip and Hilton Garden Inn in the Lekhwair & Al Ghobra areas also come highly recommended for being surrounded by many dining options, although they are not by the beach.

For those who prefer scenic views between the beach and mountains, travelers have called out the area around the Hyatt and Intercontinental, as well as east of Muscat towards Al Bustan Palace as ideal locations. These areas are noted for their posh atmosphere and great beach access.

Some travelers noted that the Royal Tulip is a dry hotel without alcohol, which might be a consideration for some visitors. Nearby alternatives like the Park Inn by Radisson offer alcohol and are still close to great restaurants.
