Frequently Asked Questions
You can rent all our water equipment (kayaks, SUP boards, big SUP) directly online through the booking cards on this page. Just choose the date, time, and type of watercraft 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 warm days. Plus, by booking online, you'll save time and avoid waiting.
Yes, all members of the Real Club de Tenis de San Sebastián enjoy special rates and priority access for both boat rentals and registration for our sports school and nautical courses.
Absolutely. 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 you quickly gain confidence in the sea. For 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's an unforgettable experience to enjoy the San Sebastian coastline.
Completely. La Concha Bay and the Ondarreta area offer exceptional conditions as they are highly protected from strong swells. It is one of the best environments in the Cantabrian Sea to start water sports safely. And if 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 our priority. If the Club's technical team determines that the weather conditions (wind, swell, storm) are not safe, the activity will be suspended and we will offer to postpone your reservation or provide a full refund.
Generally, the early hours of the morning offer the calmest sea ("glassy mode") and less wind, which is ideal for Paddle Surfing. Sunsets are also magical, which is why we offer specific routes to enjoy the sunset from the water.
Reaching Santa Clara Island is our star route and is highly accessible from our facilities in Ondarreta. During the summer season, you must moor 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 about local currents and recommended crossing areas according to the tide conditions before you hit the water.
All our Itsas eskola reservations include: the watercraft (kayak, SUP board, Big Sup,...), the corresponding paddles, a mandatory and approved life jacket, plus prior advice from our instructors.
Yes, the Real Club de Tenis de San Sebastián facilities have fully equipped changing rooms, showers, and lockers available to Itsas eskola users for a completely comfortable experience. The Itsas eskola itself has lockers and cold water showers, ideal for shortening entry and exit times.
Yes, we have a specific "Board and Kayak Storage" service. This service is exclusive to members. We have a storage facility just 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 and double kayaks, as well as family models specifically designed to enjoy a quiet route through the Bay in the company of the youngest members of the family.
In the summer months, a swimsuit, a lycra-type shirt (for sun protection), a cap, and sunscreen are enough. Off-season or on cool days, we recommend wearing a thin wetsuit. The Itsas eskola of the Real Club de Tenis de San Sebastián provides wetsuits. Don't forget to bring footwear that can get wet (neoprene booties or closed sandals). If you wear sunglasses or prescription glasses, it is better to wear them with a strap.
Yes, it is a strict rule. Due to legal requirements and basic maritime safety, anyone renting nautical equipment or participating in our Itsas eskola courses must be able to swim fluently.
For free rentals 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 camps), the minimum age is usually set from 8 years old (subject to swimming level).
Absolutely yes. The use of a fastened life jacket is strictly mandatory at all times while navigating, regardless of your experience level, age, or even if you stay within the protected area of La Concha Bay.
To get to 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 moor your board or kayak to the buoys near Santa Clara Island and swim to it.
We have giant boards (Big SUP and Dragon Board) approved for groups of 4 to 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.
