The Southern Coast of Portugal, also known as the Algarve, has some of the most beautiful scenery in the world. With clear water and so many different shades of blue, I felt like I was visiting the Caribbean when I was actually on the beautiful Algarve beaches. The cliffs and different rock formations along the coastline are breathtaking.
The best way to appreciate the Algarve caves in Portugal is by boat because you can reach areas that are not accessible from the beaches. We decided to try one of the Bom Dia boat trips from Lagos.
Read my detailed review to help you decide if it’s a boat tour that you would like to do when you visit the Algarve.

Algarve Boat Tours with Bom Dia
Bom Dia offers several different Algarve boat trips that will show you the grottos near Lagos, so you will be able to find one that fits your schedule and budget. We took the two-hour tour and had a great time. They also have fishing and dolphin watching tours in the Algarve.

Their Algarve cave tours leave from the Lagos marina. We found the Bom Dia sales booth by the marina and were directed across the bridge to where we would catch the boat. At first, I was worried we were in the wrong place because I did not see a Bom Dia boat, but then I saw a gentleman wearing a red shirt with a Bom Dia logo.
A few minutes later we saw a Bom Dia boat arrive. It was a large sailboat that was pulling a smaller motorboat behind it. The passengers quickly disembarked and they were ready for us. We boarded the boat and had plenty of space to spread out.

Setting Sail for the Algarve Caves
Pretty soon, we were ready to set sail on our Algarve tour. We left the Algarve marina and moved into open water, which was surprisingly calm. The crew raised the sails and we relaxed and enjoyed the ride.
They had beverages available for sale for those that were interested. I couldn’t have asked for a nicer day, the sun was shining and it was probably about 75 degrees – not bad for the Algarve in April.
The water was calm, so the sailing was relaxing. As expected, it was a bit windy, so I was glad I wore my hair up. One passenger had his hat blow off his head, so if you bring one, you need to hold onto it! When we got close to the Algarve sea caves, the crew pulled in the small boat.
Half of the passengers got in the small boat and headed to the grottos.
We stayed on the big boat and relaxed, our turn would be next.They asked if we wanted to get in the water. I did have my swimsuit on, but I hadn’t brought a towel. The water is clear so I was tempted but then decided it was probably too cold. Looking back now, I wish I would have gone in.

Our Lagos Cave Boat Tour
Then it was our turn to see the Algarve caves. We climbed from the big boat to the smaller one, a pretty easy transition since the water was so calm. We were told to sit in the back because the ride would be smoother. On this boat, we had to put on life jackets, and then we were off.
The rock formations were even more impressive close-up. Depending on how you looked at the Portugal caves you could see different images. Our captain pointed out King Kong, an alligator, and even Michael Jackson. You could also see shells in the rock and in some places the rock looked like it was coral.

We went in and out of several Lagos caves and admired the impressive cliffs. We also saw some beaches but the stairs to get to these beaches looked a little intimidating. If you want to see the Algarve cliffs, a boat ride is definitely the way to go.
Then it was time to head back to the sailboat. As we approached it, we saw there was a police boat moored alongside. I was a little worried at first, but then I was told it was just a routine inspection. We got back on the sailboat, and I saw one of the ladies was relaxing in the water. I asked her how it was and she said it was a bit cold but she was enjoying it. I wish I had taken the opportunity to swim!

Heading Back to the Lagos Marina
She got back on the boat and then we headed back to the marina. It was an afternoon well spent. I enjoyed our Algarve cruise experience. The caves in the Algarve were beautiful and we had a great time exploring them. The staff was very professional with a good sense of humor. I would love to do one of the longer Lagos boat trips next time I am in the area.

What to Bring on Your Algarve Boat Tour
We didn’t bring anything with us besides our camera gear since it’s only a two-hour boat trip. I wish I would have been more prepared! I would have loved to be able to spend some time in the water. The next time I do a boat cruise in the Algarve, I will bring:
- Sunscreen (and make sure I apply it in advance)
- Bathing Suit (I would wear it under my clothes)
- Towel
- Camera (The GoPro is perfect since it’s waterproof.)
If you like to wear a hat, make sure it is one that can handle the wind. A fellow passenger on our tour lost his in a gust of wind.
Is an Algarve Boat Tour suitable for children?
While our boat tour did not have any kids on board, it would have been fine for kids. It was a smooth ride.

More Algarve Caves
The Algarve coastline is about 100 miles long, so Lagos is not the only place to see Algarve Caves. Benagil might be the most famous cave, however, our Bom Dia tour did not go there.
While pictures of the Benagil Cave look amazing, I have read that it gets very crowded with boats and they only stay inside for a few minutes. The boat tours are not allowed to let people out inside the cave.
If you do have your heart set on visiting this cave ask to make sure the tour you choose includes it. You can find several boats that will take you there from Benagil beach.
Note: The Benagil Cave is only accessible from the water. The Seven Hanging Valleys hike is nearby but does not take you inside the cave.
Is a Algarve Boat tour worth it?
Yes. Some of the beauty of the Algarve coast can only be seen from the water. Our boat tour to see the Algarve caves was one of the highlights of our road trip in Portugal. It’s a relaxing experience that I would love to do again.
Have you ever done a boat tour to see grottos? If you haven’t I would definitely recommend doing one of the Algarve boat tours from Lagos Portugal!

Expert Tips for seeing the Algarve Caves
- Bom Dia offers several different Algarve tours of varying lengths and prices. You can even do one to see the Algarve dolphins.
- It may be windy. Be careful if you decide to bring a hat on board, it may blow away! If you have long hair, I would recommend wearing it up.
- Don’t forget your sunscreen and apply it liberally. I did get a little sunburnt.
- Bring your bathing suit and a towel so that you can enjoy the lovely water.
- You will also want to explore some of the other great beaches in the Algarve.

Awesome!!! ? #bucketlist.
Thanks so much Shishi! I hope you get to check it off one day!
Such wonderful natural features! I love that one formation looked like Michael Jackson ?
Thanks Lorna. Yeah it was fun to see different objects/people in the rocks!
I traveled to Algarve when I was a kid and I remember me jumping from the cliffs to the sea! Your post took me back to those days 🙂 Thanks
On my gosh! That sounds dangerous! But glad I could bring back memories.
The sunscreen reminder is a good one for me – being on the water like that would definitely leave me red as a tomato. 🙂
Haha yes, the sun there is pretty strong.
I love any excursion on the water, so this looks like a great trip for me!
Leigh – The water was just lovely, so I’m sure you would love it!
Beautiful caves, I’d love to visit Portugal too.It’s lovely you had such a beautiful day there. Those rock formations remind me of Capri, in Italy.
Thanks Anda. Yes we were lucky with the weather. And yes, I hadn’t thought of it, but now that you say it, I think it is similar to Capri.
The water is beautiful!! I love taking boat tours, so I’ll definitely have to do this one! 🙂
Julie – Thank you. Yes We had a great time, so I am sure you would too.
Hold everything…Michael Jackson in a rock formation? That’s a “Thriller”! 🙂 It sounds like you had a great day – we absolutely love being out on the water, especially on calm, sunny days like you had. Bom dia, ideed! The Algarve has long been on our Bucket List, but had not heard much about the caves – thanks for sharing!
Haha! You guys are funny. Yes you should be sure to do a boat trip when you make it to the Algarve.
I would love to see the Algarve! And seeing the caves by boat definitely sounds amazing!! Damn it! My bucket list just keeps growing longer and longer!! 😉
Justine – Thanks for your nice comment and yes I have the same problem!
I’ve already heard that the coast of Portugal is known for its impressive caves and rock formations ! Looking at the video, many of these caves seem much larger than I thought. I guess watching the ocean’s green waters glimmer along the ceilings of these caves is probably stunning 🙂
Yes, it really is a beautiful place and the caves were impressive.
I’ll be going here in August! I can’t wait!
Laura – That’s great you will love it!
I’m heading to Lisbon in a few weeks! Now I’m considering making a day trip to these caves. Looks like a cool experience!
Jewels – That is so exciting. We went to Lisbon as well and loved it. More coming up about that on the blog soon.
This looks amazing. A nice mix of culture and scenery and beach. I love Portugese seafood, too. So I can’t imagine not liking it here.
Eileen – Yes, the seafood all over Portugal was amazing! I really loved the sardines in the Algarve.
What fun Anisa. We’re just back from Capri where the scenery is very similar. Saving for our mega Euro road trip itinerary
Nice! Yes it is similar to Capri. I can’t wait to hear about your mega UK road trip!
Oh, I need to go here. We’ve been to Spain, but have yet to get to Portugal. I’m thinking we may be able to get there in 2018. If so, I am going to check out these caves. Amazing!
Kristi – Yes. We actually did a road trip to a few places in Portugal and loved all of them. More about it coming up on the blog.
My mom has wanted to go here for so long, I sometimes this about surprising her with a trip here! I think she would really love it! #TheWeeklyPostcard!
Lolo – It really is lovely! The area is just so beautiful and laid back. Plus the seafood is so good! I hope you get the chance to take her.
Love the video! Algarve Caves look really awesome! I have yet to decide if I want to travel south in Portugal because I only have 10 days and the weather might be a bit cold in Sept, in the waters?? Oh well, I still have a couple of months to think about 🙂 #TheWeeklyPostcard
Kat – Thank you. Actually I think September would be perfect there. It should still be nice and the crowds should have left!
Oh, I LOVED the Algarve when I visited! It was beautiful!! We went during March, so it was a bit too cold to explore the caves by boat, but I definitely want to go back and see more of the area and to finally be able to visit the caves!
Cassandra – Yes you need to go back it’s such a great area with so much to do!
Oooo… I might be heading to Portugal at the end of the summer! This is definitely being added to the list of spots to check out!
Lindsay – That sounds great, you will love it. More about my Portugal trip coming up on the blog.
