I would recommend snorkeling the island of Gili or the island of Lombok

If the goal is just the island of Bali, then a good snorkeling off the coast of Amed (a very quiet place) , yet in the Lagoon of Padang Bai near Chandidasa (in Chandidas there are restaurants, etc.), and in the sea park of the island of Menjangan

At the most popular resorts of southern Bali, there is no interesting snorkeling near the coast, but dive centers organize day trips for snorkeling to Nusa Penida and Nusa Lembongan, as well as to other places.

Yes, there is, but not at all in the popular tourist area in the south of the island

This place is in the east of the island and is called Amed, which is essentially an area consisting of several villages Amed is not similar to other areas of Bali, it is located along the coast with a length of 10-12 km, it is possible to get to Amed via Candidasa on the main road and in time it will take just over 1 hour.

The main reason for coming here is just snorkeling and diving. Hotels here at different levels, here I can recommend The Griya Villas and Spa 5 * or Arya Amed Beach Resort 4 *.

Tulamben is also suitable for snorkeling. Go to it 2, 5 - 3 hours. A fairly undeveloped place, at the foot of the volcano, is not far away from Lovina. Hotels here are not of high category, for example, Kubu Indah Dive & Spa Resort 4 * or Liberty Dive Resort 3 *.
