Which section this is
The Transcarioca describes this route as Represa dos Ciganos → Bom Retiro, within Tijuca National Park. It lists 9.5 km · approx. 5 h and rates the difficulty as High. Navigation, trail markings, sun exposure and water details appear in this page’s quick guide. They are a reference for comparison, not a substitute for park notices or an assessment of trail conditions that day.
Tijuca National Park lists general opening hours every day from 8 am to 5 pm. Those hours alone do not confirm that every gate, road, trail or service is open. Before setting out, check official notices and the latest entry time for the access point you plan to use.
What you’ll see
Represa dos Ciganos, the ruins of Fazenda Boa Vista, the rock walls of Tijuca Mirim, Pico do Tijuca Mirim, Pico da Tijuca and Largo do Bom Retiro. The source also notes that the reservoir supplies water: do not swim there.
The reservoir is not a swimming pool
Represa dos Ciganos is a water-supply reservoir, and swimming is prohibited according to the trail guide. Even if a pool or reservoir looks calm, it is not an authorized recreation area. I observe from a permitted area and keep walking.
History among ruins and forest
The Transcarioca highlights the ruins of the former Fazenda Boa Vista and the rock walls of Tijuca Mirim. It also mentions Pico da Tijuca and Pico da Tijuca Mirim. Together, these places tell a story of natural landscape and human occupation, not simply a climb to a summit.
How to prepare and when to start
I prefer a stable-weather morning and an early start, once access is confirmed open. Allow for the hike, breaks, photos and return; do not use the estimated duration as your only planning time. Bring your own water, some food, sun protection, insect repellent, grippy shoes, a light layer and an offline map. Slow down on scrambling sections, mud and wet rocks.
If there is heavy rain, a storm, slippery ground or poor visibility, I leave the mountain for another day. Do not enter reservoirs or waterfalls where swimming is prohibited, and do not feed wildlife.
Map, endpoints and return
The official guide places the reservoir entrance opposite Hospital Cardoso Fontes. This map shows the general area, not CEDAE’s gate or the track. Use the downloadable Transcarioca route for navigation. I do not use this page’s map as a track or directions. If the start and finish differ, plan your return in advance; do not assume rideshare will be available at the exit.
What to combine it with
This is a long, demanding hike. I would not add another summit trail on the same day. If you have energy left and the park is still open, take your time in a permitted area of Bom Retiro; otherwise, arrange your return and save the rest for another day.
