The shorter southern routes mentioned below are for visiting the Mekong Delta, seeing the floating market and/or Phu Quoc island. There is also one larger route to the north of the HCMC which includes the mountains of Dalat, the beaches of Nha Trang, the central highlands of Buon Ma Thuot and back to HCMC. While the riding in the north provides the best views, in the south there is more variety.
3 days – Mekong Delta / Floating Market
This is the shortest route for visiting the Mekong Delta, the floating market and the small islands at My Tho.
4+ days – Phu Quoc Island and Mekong Delta
This route follows the same path as the shorter route above but continues to Phu Quoc island to see some of the nicest beaches in Vietnam. The route is at least 4 days but can be longer with extra nights on the island and maybe 1 night in My Tho.
7 days – Southern Mountains and Beaches
This is the only route in the south to offer beaches and mountains. It heads to Dalat and then Nha Trang. You can spend a full day exploring waterfalls around Dalat before heading to Nha Trang. The roads coming out of the mountains towards the coast is what makes this route special. This route also offers the chance to go to Cat Tien national park and the Cu Chi tunnels. If you have the time it is a nice loop to do in the south and can be combined with the first 2 routes which head to the Mekong Delta and Phu Quoc island.
