Rules on the Isar (boating regulations) and tasks of the Isar rangers
The Isar is the lifeline of the district of Bad Tölz-Wolfratshausen and meanders from the south via the Sylvensteinsee lake to the northern border of the district near Schäftlarn.
It is under special protection and flows through landscape conservation areas and nature reserves. In these protected areas as well as on the Isar itself, rules, prohibitions and bans apply. They are important - because whether on the Isar or in our other protected areas:

Boating regulations
Regulation of public use on the Isar in the district of Bad Tölz-Wolfratshausen
According to the so-called public use regulation "Boating" and the supplement dated January 3, 2022, it is permitted to use the Isar in the district of Bad Tölz-Wolfratshausen between June 1 and October 15 (up to Bad Tölz) and from June 1 to December 31 (downstream of Bad Tölz).
In detail:
June 1 to October 15. October: This period applies to the section of the Isar in the district of Bad Tölz-Wolfratshausen from the southern district border with the district of Garmisch-Partenkirchen (Fkm 244.04) to the Sylvensteinsee bedload barrier (Fkm 230.50) and in the section of the Isar below the Sylvensteinsee (road bridge B13 / Fkm 224.00) to the northern district border with the district of Munich (Dürnsteinerbrücke near Schäftlarn / Fkm 169.40).
June 1 to December 15: This period applies to the section of the Isar from Bad Tölz (Isar power station / km 199.005) to the district border with the district of Munich (Dürnsteinerbrücke near Schäftlarn / km 169.40), in which the Isar may be used for a little longer.
If temporary closures of sections of the Isar become necessary at short notice during the course of the year - e.g. due to flooding - you will be informed.
Public use means the private use of the Isar.
- The following vehicles are permitted: small watercraft without their own propulsion (e.g. canoes, kayaks, Canadian canoes, inflatable boats, white-water suitable/air-filled boats, vehicles that can be maneuvered with a double paddle). Electric motors for boats, SUPs, etc. that require a permit are not permitted in order to calm the waters and protect nature.
- A dinghy may not be attached or boats hooked together.
- No alcohol! Boaters must not have 0.25 mg/l or more alcohol in their breath or 0.5 per mille or more in their blood.
- Children up to the age of 12 and non-swimmers must wear suitable life jackets.
- No glass bottles or glass containers to avoid shards.
- You are only allowed to travel on the Isar between 7 am and 8.30 pm
- No more than the permitted number of people may sit on a boat. In general, there may not be more than 12 people.
- Stay in the current line or along the deep channel; boats etc. must not be pulled through shallow water zones
- Keep your distance from gravel islands and gravel bank areas.
- Quiet is better! Sound amplifiers and loudspeakers must not be used.
- "Sump jumping" is not permitted.
Central regulations from the ordinances in landscape conservation areas and nature conservation areas
- Gravel islands may not be entered at times, as this endangers the survival of some gravel breeders.
Some areas are marked with signs as bird breeding grounds and are therefore closed to visitors from March to July. The so-called gravel breeders - for example the endangered little ringed plover - lay their eggs in the middle of gravel banks. A careless step on such a barely visible egg could result in the loss of a year's offspring. - Open fires are also not permitted (including barbecues). The risk of forest fires is too great. In Bavaria, there is a general ban on open fires less than 100 meters from the nearest forest. In many places, however, the banks of the Isar border directly on forest areas. In addition, abandoned fires and garbage have a negative impact on nature.
- Camping in the protected areas is also not permitted. Waste is often left behind. The numerous visitors disturb the animals living here during the day, which should at least have an undisturbed habitat at night.
Violations are reported to the lower nature conservation authority, where fine proceedings are initiated.
What do the rangers actually do?
Our Isar rangers in the district are out and about every day along the Isar and at Walchensee, informing recreational visitors about the wildlife, flora and fauna along the Isar and keeping a watchful eye on what is happening along the river.
In the event of infringements, they are allowed to record personal details so that the offenders can be prosecuted by the district office. The police can also be called in.
The Isar Rangers have a variety of tasks:
- They maintain paths,
- carry out mowing work to protect the habitat of endangered species such as the spotted grasshopper.
- They also provide information boards and signage for the protected areas.
- They make a valuable contribution to environmental education with excursions for school classes and other interested citizens.
- The rangers are also important contacts for nature conservation associations and the police.
- Conversations with recreationists are indispensable in public relations work.
- They remove garbage and fire pits.
- And very importantly, the Isar rangers make sure that the regulations of the protected areas are observed.
The Isar and its floodplains are designated as a landscape and nature conservation area in the district of Bad Tölz-Wolfratshausen and are therefore subject to the relevant regulations. The aim is to preserve the diversity and beauty of the landscape and protect the flora and fauna, but also to maintain the area as a recreational area for citizens.
