Dungeons and Dragons (D&D) 5th Edition offers several excellent starting campaigns that are designed specifically for new players and Dungeon Masters. Here are a few popular options that are often recommended:

1. Lost Mine of Phandelver: This is the introductory campaign included in the D&D 5th Edition Starter Set. It’s designed for beginner players and Dungeon Masters, providing a well-structured adventure set in the iconic Forgotten Realms setting. Lost Mine of Phandelver offers a mix of combat, exploration, and roleplaying opportunities, making it a great starting point for new groups.
2. Dragon of Icespire Peak: This campaign is included in the D&D Essentials Kit, which is another introductory set aimed at new players and Dungeon Masters. Dragon of Icespire Peak takes place in the same setting as Lost Mine of Phandelver but offers a different adventure and new challenges. It provides a sandbox-style experience with various quests and opportunities for the players to explore and interact with the world.
3. Waterdeep: Dragon Heist: This urban adventure is set in the bustling city of Waterdeep, offering a different flavor compared to traditional dungeon-crawling campaigns. It involves intrigue, heists, and political maneuvering, making it an excellent choice for players who enjoy roleplaying and urban environments. Waterdeep: Dragon Heist provides a good balance of social interaction, exploration, and combat.
4. Curse of Strahd: If you’re interested in a more Gothic and horror-themed campaign, Curse of Strahd is a highly acclaimed choice. It takes place in the dark realm of Barovia, ruled by the enigmatic vampire lord, Strahd. This campaign offers a rich and atmospheric setting, challenging encounters, and a deep narrative that immerses players in a world of darkness and dread.
5. Storm King’s Thunder: This campaign takes the players on an epic adventure involving giants and the fate of the Sword Coast. It provides a grand-scale storyline, allowing players to explore the vast world and interact with different factions. Storm King’s Thunder offers a mix of exploration, combat, and diplomacy, making it suitable for players who enjoy a diverse range of gameplay experiences.

These campaigns are well-regarded for their engaging stories, balanced encounters, and opportunities for character development. However, the “best” campaign ultimately depends on the preferences and interests of your group. Consider discussing with your players what type of adventure they would enjoy most, whether it’s a classic dungeon crawl, an urban intrigue, or an epic quest, and choose a campaign that aligns with those preferences.
