Any suggestions in the marketplace for a D&D adventure for 3 to 4 players?

Thank you!

What level? How long do you intend the campaign to last? What sort of adventure would you like to run? There are a lot of possibilities, so listing some parameters would help give better suggestions.

Every single DnD adventure available is designed for 4 Players! The adventures considered the highest quality for 5th edition tend to be Curse of Strahd and Tomb of Annihilation. They both have excellent art, amazing stories and well written adventures, with copious amounts of support from the community on their respective subreddits and on places like the DMs Guild for supplemental material.

Maybe level 1?  Just wanna play with my X2 teenage sons and I'll be DM and run 1 NPC.  Nothing too complicated.  Just something to horse around with 2 to 3 hours on some weekends.  Any other parameters that are helpful?

Hi Steve! Unofficial recommender here. :) What kind of games do your sons enjoy (combat heavy? roleplay?) or are they new to the game?

I’d suggest you take a look at  The Master’s Vault  to start with. It’s a free D&D 5th edition one-shot that is specifically designed for new players and DMs to learn both 5E and the Roll20 system. It’s designed for level 1 with pre-generated characters, should take about 6-8 hours, and ends with a pretty strong hook that you could tie into any other adventure afterwards.
