If you wish to visit Alfaz del Pi (Albir Beach) and Altea city located near Benidorm the best way is to use the tourist bus service, moreover, you can combine it with a small Benidorm sightseeing tour.
So ... What would i advise ...
Take the two-storey tourist bus number 30 at the Cala de Finestrat bus stop, or at the bus stop near the hotel "Gran Hotel Bali". It departs from the hotel "Bali" every hour starting 10:30. I need to say that the schedule is not always held on time. The bus can come a little earlier (10-15 minutes) or later (also 10-15 minutes). The single ticket cost for the bus is 5 euros but it is better to buy a tourist travel card for 24 or 72 hours. It cost 9.50 and 19.50 euros, respectively. These cards are very convenient, because they allow you to use an unlimited number of times all Benidorm city buses including two-storey tour buses, buses to Guadalest or waterfalls of Algar in Finestrat. At any stop, you can go out for a walk, and then continue your bus trip. You can purchase the card directly from the bus driver.
On the bus N 30 you can get to its final stop in the Rinc?n de Loix at this docking stop you can change to the bus N 31. Bus schedule is organized in such a way that you always have 10-20 minutes to look around and to take another bus. You wont pass the last stop, you will see exactly the same two-storey tour bus waiting there.
Then you can continue your trip by bus N 31. The route starts from the Levante beach to Albir beach side and further leads to the town of Altea. On the way you can listen to broadcast in several languages, including English. We recommend you to get out of the bus and take a walk at Albir , this small cozy town is totally different from Benidorm and has it own charm . Then give yourself a couple of hours to relax at Altea village with its unique old town atmosphere.
The road back will be exactly the same. From Altea or Albir by bus N 31 to Rincon de Loix district of Benidorm, where you change to the bus N 30, which is already waiting for you at the bus stop and then get to the hotel "Bali" stop or La Cala de Finestrat.
Some photos taken during the trip.
