Before visiting Marjan Island, keep in mind that access to the island is typically through resorts or private transportation. While the island is accessible to the public, many areas are part of exclusive resorts, so access may be limited. If you're planning to stay for an extended period, consider booking your accommodations in advance, especially during peak seasons. The island is ideal for a day trip, but if you’re staying overnight, be sure to check availability at the resorts. The island also offers some activities like boat tours and diving, which may require booking in advance.

To get to Marjan Island, you can take a taxi or private car from Dammam city center, which is about 20-30 minutes away. The island is easily reachable via King Fahd Causeway, which connects Dammam to the coastal areas and resorts of the island. If you are staying at a resort on the island, transportation may be arranged for you. There are no public ferries directly to the island, so private transport or resort shuttles are the most convenient options for getting there.

The best time to visit Marjan Island is during the cooler months, from November to March, when the weather is pleasant and ideal for outdoor activities. During the summer months, temperatures can be very high, making the island less comfortable for prolonged outdoor exposure. If you're visiting for a relaxing beach day or water activities, it’s best to go in the morning or late afternoon to avoid the heat and enjoy more comfortable weather. Weekend visits are popular, but if you prefer a quieter experience, weekdays are ideal.

Marjan Island is a great starting point for exploring more of Dammam and the surrounding area. After enjoying the tranquility of the island, head to the Dammam Corniche for a scenic waterfront stroll, or visit the nearby King Fahd Park, one of the largest parks in the region. You can also explore the Half Moon Bay for a fun day at the beach with water sports and picnic areas. For those interested in history, the Heritage Village offers a glimpse into the traditional culture of Saudi Arabia. A visit to the neighboring city of Al Khobar, known for its lively dining scene and waterfront, is another excellent day trip option.
