Frequently Asked Questions
You can rent all our nautical equipment (kayaks, SUP boards, big SUPs) directly online through the reservation cards on this page. You just have to choose the date, time, and type of boat to enjoy La Concha Bay at your own pace. In addition, the Real Club de Tenis de San Sebastián also manages kayak rentals right on Ondarreta beach through Ondarreta Kayak by Real Club de Tenis de San Sebastián.
We highly recommend booking in advance through our website, especially during the summer season (June to September) and on weekends, as rental equipment tends to sell out quickly on hot days. Plus, with online management, you will save time and avoid waiting.
Yes, every member of the Real Club de Tenis de San Sebastián enjoys special rates and priority access to both boat rentals and registrations for our sports school and nautical courses.
Of course. If you want to learn paddling technique and balance in a personalized way, we offer private lessons adapted to your level. Our instructors will guide you step by step so that you quickly gain confidence in the sea. Regarding stand up paddle, the Itsas Eskola of the Real Club de Tenis de San Sebastián offers the Taste Sup activity, which teaches you how to paddle on the board with an instructor for 30 minutes and offers another 60 minutes of free paddling.
It's a perfect gift! You can book any of our routes, courses, or rental vouchers and contact our offices to request a gift voucher format. It is an unforgettable experience to enjoy the San Sebastian coastline.
Absolutely. La Concha Bay and the Ondarreta area offer exceptional conditions as they are very protected from strong waves. It is one of the best environments in the Cantabrian Sea to start water sports safely. And if the conditions do not allow it or are not safe, our team will let you know and you will not be able to go out.
Safety and a good experience are the priority. If the Club's technical team determines that the weather conditions (wind, waves, storm) are not safe, the activity will be suspended and we will offer to postpone the reservation or provide a full refund.
Generally, the early morning hours usually offer the calmest sea and less wind, ideal for Paddle Surf. Sunsets are also magical, which is why we offer specific routes to enjoy the sunset from the water.
Reaching Santa Clara Island is the star route and very accessible from our facilities in Ondarreta. During the summer season, you must tie your board or kayak to the buoy and swim to Santa Clara Island. For longer routes exposed to the open sea (such as going to Sagüés or Monpás), we recommend doing so through our "Guided Tours" to guarantee maximum safety.
The activity can be done regardless of whether the tide is high or low. However, our team will inform you before going into the water about local currents and recommended passage areas depending on the state of the tide at that time.
All our Itsas eskola reservations include: the boat (kayak, SUP board, Big Sup...), the corresponding paddles, a mandatory and approved life jacket, as well as prior advice from our instructors.
Yes, the facilities of the Real Club de Tenis de San Sebastián have fully equipped changing rooms, showers, and lockers available to Itsas eskola users so that the experience is completely comfortable. The Itsas eskola itself has storage and cold water showers ideal for shortening entry and exit times.
Yes, we have a specific "Board and Kayak Storage" service. The service is exclusive to members. We have a warehouse a few meters from the sand of Ondarreta beach so you don't have to transport your heavy equipment every day.
We have a large and renewed fleet that includes single, double kayaks, and family models specifically designed to enjoy a quiet route through the Bay in the company of the little ones of the house.
In the summer months, a swimsuit, lycra shirt (to protect you from the sun), a cap, and sunscreen are enough. Out of season or on cool days, we recommend wearing a thin wetsuit. The Itsas eskola of the Real Club de Tenis de San Sebastián has wetsuits. Don't forget to bring shoes that can get wet (water shoes or closed sandals). If you bring sunglasses or prescription glasses, preferably with a strap.
Yes, it is a strict rule. Due to legal requirements and basic maritime safety, anyone who rents nautical equipment or participates in our Itsas eskola courses must know how to swim fluently.
In the free rental of family or double kayaks, children can be accompanied by adults from a young age (we recommend 9-10 years and up). For our training activities (Summer Junior School or campus), the minimum age is usually established from 8 years (subject to swimming level).
Absolutely yes. The use of a fastened life jacket is strictly mandatory at all times during navigation, regardless of your experience level, age, or whether you do not leave the protected area of La Concha Bay.
To reach the island you must always use the designated areas and avoid approaching the entrance channel for motorboats or passenger ships. Our team will visually indicate the best crossing route before you start your rental. During the summer season, you must tie your board or kayak to the buoys bordering Santa Clara Island and swim to it.
We have giant boards (Big SUP and Dragon Board) approved for groups of between 4 and 8 people simultaneously. These boards are incredibly stable and perfect for groups of friends, families, and Team Building events. The staff will advise you on the best option for the size of your group.
