To access the Nether, you'll need a Diamond Pickaxe to mine Obsidian. Craft a bucket and collect water to pour over lava, creating Obsidian. Mine at least 9 blocks. Build a vertical frame (4x5) and activate it with Flint and Steel. Step into the portal to enter the Nether. See how to build a portal: https://youtu.be/eUiZXE3tjvU
You can create a portal without diamonds using only Water and Lava buckets on a stone archway. Here is a video guide: https://youtu.be/dYO9_MoU4Vw
