Magento 2 : How can I get the sitemap in magento 2?

As of Magento version 2.1.8, the sitemap functionality is included in the admin by default.

• Define sitemap location: Marketing > SEO & Search > Site Map. You can also manually generate the sitemap file from here.

• Configure cron settings: Stores> Configuration > Catalog > XML Sitemap

Here are instructions for setting up recurring cron jobs. Just like Magento 1.x, the system's cron calls the Magento cron script, which schedules jobs.

Magento 2: By default not providing HTML Sitemap.

For Categories & Sub Categories: Getting all available category, subcategory list in magento 2

For Categories Product's: Magento 2: get product collection using category id

Magento 2 doesn't have html sitemap url for category and products like in magento 1.xx . For this, you can create a CMS page like 'sitemap/' and call a phtml file

which will include the custom code to call all category

In cms page, call this:

{{block class="Magento\Framework\View\Element\Template" template="Magento_Theme::sitemap.phtml" name="customsitemap"}}

then in phtml, call this:

<?php 
$objectManagerr = \Magento\Framework\App\ObjectManager::getInstance();
$categoryFactory = $objectManagerr->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
$categoryy = $categoryFactory->create()   
        ->addAttributeToSelect('*');
//->addAttributeToFilter('is_active',1)
//->addAttributeToFilter('is_anchor',1);
$excludedCategory = array(0);

?>

<ul class="sitelist">
<?php foreach ($categoryy as $cc): ?>
    <?php if(!in_array($cc->getId(), $excludedCategory)):?>
        <div class = "sitemap-list" style="float:left;">
        <?php if ($cc->getLevel()==2):?>
            <li>
                <h3><a href="<?php echo $cc->getUrl(); ?>"><?php echo $cc->getName(); ?></a></h3>
                <?php
                    if($cc->getChildren())
                    {
                        $sub = explode(",", $cc->getChildren());
                        $categoryFactorysub = $objectManagerr->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory');
                        $categoryysub = $categoryFactorysub->create()   
                        ->addAttributeToSelect('*');
                        $subcat=$categoryysub->addFieldToFilter('entity_id', array('in' =>$sub));

                        //$subcat->printlogquery(true);exit;
                        ?>
                            <ul style="margin-left:15px;"> 
                        <?php foreach ($subcat as $subcategories){ ?>
                            <?php if ($subcategories->getLevel()==3):?>
                                <div class = "sitemap-list">
                                    <li>
                                        <?php if($subcategories->getImageUrl()): ?>
                                        <div class="mega-menu-ad">
                                            <img src="<?php echo ($subcategories->getImageUrl()); ?>" width="25" height="25" />

                                    </li>
                                </div>
                            <?php endif;?>
                        <?php } ?>
                            </ul>
                <?php   } ?>

            </li>
        <?php endif;?>
        </div>
    <?php endif;?>
    <?php endforeach; ?>
    </ul>

This way you can easily create a sitemap URL in the Magento 2.
