Medellín Residents Discover Hidden Rock Pools for Summer Lap Swimming

Medellín's public outdoor pools logged 4,200 lap-swimming visits in the first week of July 2026, according to daily entry tallies from the Instituto de Deportes y Recreación.

The spike follows the city's annual July heat pattern, when afternoon readings often reach 28 degrees Celsius and indoor gyms report lower attendance. Local wellness programs now promote open-air water exercise to maintain cardiovascular routines without air-conditioned equipment.

Two sites stand out for regular lap swimmers. The Unidad Deportiva de Belén on Carrera 76 between Calles 8 and 10 reopened its 50-metre outdoor pool in March after new lane markers and timing clocks were installed. Swimmers there share the space with a 25-metre teaching pool used mainly before 8 a.m. Further north, the rock pools along Quebrada La Picacha in the Manrique neighbourhood offer a 40-metre natural channel cleared of debris last year by the Secretaría de Medio Ambiente. Both locations sit within 300 metres of Metrocable or Metro stations, cutting travel time for commuters who swim before work.

Access details and current schedules

Entry at Unidad Deportiva de Belén costs 6,000 Colombian pesos for adults and remains open from 6 a.m. to 6 p.m. daily. Lane reservations opened online through the IDER portal on 1 June and currently show availability before 7 a.m. and after 5 p.m. At the La Picacha rock pools, access stays free but the city asks visitors to arrive before 10 a.m. to avoid afternoon runoff. Lifeguards from the Bomberos de Medellín patrol both sites on weekdays.

City records show the Belén pool hosted 1,150 lap swimmers during the same week last year, a figure now more than tripled. The increase aligns with the rollout of the municipal “Mueve Medellín” campaign, which added water-aerobics classes at the site three evenings a week.

Practical steps for first-time visitors

Swimmers should bring their own kickboard and fins if they plan intervals longer than 500 metres, since neither location rents equipment. A quick check of the IDER Twitter feed before leaving home confirms whether lane lines remain in place after recent rain. Those heading to the rock pools are advised to wear water shoes and to exit by 2 p.m. when upstream flow can rise. Both spots connect directly to shaded walking paths, allowing a cool-down walk back to the nearest Metro station without additional transport.
